OPEN LETTER WI-FI IN SCHOOLS

OPEN LETTER WI-FI IN SCHOOLS (#3) 2012

http://www.magdahavas.com/open-letter-wi-fi-in-schools-3-2012/

May 2012.  At the request of some teachers I have updated the open letter I wrote in May 2009 about Wi-Fi in the school environment. Much has happened during the past 3 years making it even more urgent that a moratorium be placed on the deployment of Wi-Fi in schools; and that schools that currently have Wi-Fi consider reducing the microwave exposure as much as possible for part or the entire day and for part or the entire school by returning to the use of wired connections (ethernet or fiber optics) for internet access.

（槟城24日讯）槟城电磁波辐射公害防护协会反对教育部推行的全新学校无线互联网系统“1BestariNet”，来自民政党的该协会医药顾问涂仲仪医生更不顾国阵同僚之情，斥责教育部及卫生部“无知、无良”。

该协会指出，“1BestariNet”学校无线互联网系统采用全球微波接入互操作性（WiMAX）技术连接网络，以及校内使用WiFi无线上网技术，都是被国际癌症研究机构列为“2B级可能致癌物”等级，对学生构成严重负面影响。

辐射等同柴油排气氯丹

“你能让柴油车的排气，或氯丹这种有机氯杀虫剂每周5天飘进教室里吗？因为WiMAX和WiFi无线电频率辐射无线和柴油排气和氯丹等同样属‘2B级可能致癌物’。”

反对置无线上网 公园是休闲不容受辐射

二零一一年九月十六日 凌晨十二时四十三分

（槟城15日讯）槟州电磁辐射公害防护联盟呼吁当局在生活环境中采取“预警原则”，勿在槟岛市政局公园（前称青年公园）装置无线上网设施，如果真的要安装，可设立一个小亭提供上网服务，并表示去公园是休闲，不容受到辐射！

预警原则定义为尤其在学校、公园、医院和人口密集的住宅区，尽量让上述设施远离这些敏感地区。日前报道指岀，立通公司将在槟岛市政局安装免费上网热点，让民众可在公园内上网，工程预计10月安装完毕，年杪料可启用。

槟州电磁辐射公害防护联盟秘书王美丽于周四的记者会上表示，站在预警原则的角度，该联盟不赞同辐射性的上网设施安装在公园、学校等地，而站在人道立场，希望相关单位谨慎处理，同时不应太过迁就一些人的需要而伤害其他人。

她说，如果有关单位欲在市政局公园安装相关系统，可设立一个亭子提供上网服务， 没有必要覆盖100％范围。“吸烟有禁烟区，如果可固定一个地点为无线上网区，这样就可照顾敏感的一群。”

她说，槟地方政府委员会主席曹观友也认同有关预警原则，同时在去年11月的槟城论坛上也有商讨此问题，因此，将致电曹观友，向他反映此事。她提及，无线上网与电讯塔结构虽然不同，但同样可发出不同程度的电磁波辐射。

她提及，也将通过电邮的方式发出公开信予槟国、州、市议员，向他们传达此讯息。

联盟副主席李斯杰表示，赞赏槟首长林冠英于2007年，谴责马六甲州政府在一所学校附近架起电讯塔，因此希望首长来到槟城后，也关注槟城的情况。

联盟医药顾问涂仲仪医生表示，在预警原则的前提下，地方政府应采取积极的态度，先告诉电讯公司和立通公司应远离敏感地点。

他说，如果要装也应装置在特定地区。“去公园是休闲，不是受到辐射，据了解，一些患病者早上前往市政局公园进行能量修复和运动，政府应阻止有关公司在该处设立无线上网系统，避免不必要的辐射影响。”

王美麗：根據預警原則 公園不應設無線上網

• 中国报北馬

15/09/2011 21:55

（檳城15日訊）檳州電磁輻射公害防護聯盟秘書王美麗認為，檳島市政局公園不應裝置免費無線上網，因為在“預警原則”中，是不應讓公園暴露在射頻輻射下，她建議將上網熱點設在公園某特定角落。

　她是對負責裝置全檳無線上網的立通國際有限公司，日前向媒體指出該公司將在上述公園設無線上網熱點一事，如是指出。

　“該聯盟也致函檳州政府、檳島市政局及立通國際有限公司，要求關注此事。”

　她指出，根據預警原則，是不認同具有輻射的設施建立在學校、公園、圖書館、醫院等，因此有關當局，不應在這些敏感地區裝置無線上網。

　“大部分到公園的人都是去運動，很少會帶手提電腦上網。”

　她指出，既然設有抽煙區和禁煙區，就應也設有無線上網區和非無線上網區。

建議設在特定角落

　王美麗是今日召開記者會上，如是指出。

　出席者包括該聯盟副主席李斯傑、醫藥顧問涂仲儀醫生。

　王美麗指出，檳安醫院與韓江學院也有免費無線上網，這些都是不應該的。

　她說，會在今日將公開信電郵給全檳國州市議員與立通公司，並將致電掌管檳州地方政府委員會的曹觀友，表達在市政局公園裝置無線上網的意見。

　她說，曹觀友在去年4月已接受預警原則，取消原本設在五條路公園還未操作的上網設施，這證明州政府實施預警原則。

反對台北市政府設置「WiFi無線上網」聲明

反對台北市政府設置「WiFi無線上網」聲明

台灣電磁輻射公害防治協會聲明新聞稿 2011//7/2


反對台北市政府設置「WiFi無線上網」聲明


反對食品博士郝龍斌市長讓台北市民吃

「WiFi無線上網電磁波」(2B致癌劑)

「WiFi無線上網電磁波」等同「無形塑化劑」，為「2B致癌劑」


本會反對台北市政府於醫院、公車、捷運站及市府等公共空間設置「WiFi無線上網」，因為其會發出為射頻電磁輻射，屬於「2B致癌劑」，而司機可能長時間暴露，引發心臟血管疾病、可能導致交通危險事故，病患可能到聯合市立醫院就醫暴露而導致病情加重，吾等認為身為食品博士又擔任過環保署長的郝龍斌市長做了不好示範及決策，本會要求郝市長應重新審議「WiFi無線上網」危險性及必要性，暫緩或廢止該計畫，也希望郝市長能儘速舉辦公聽會，讓市民大眾了解電磁波2B致癌物的危險性，本會反對理由如下:


一、 世界衛生組織附屬單位癌症研究機構IARC已於2011年5月31日將射頻電磁輻射定為2B致癌物，「WiFi無線上網電磁波」為射頻電磁輻射，同塑化劑、DDT等，都屬於2B致癌物，郝龍斌市長為食品專家，相信其反對吃塑化劑，但為何其卻要於醫院四處設置可能會導致癌症的「WiFi無線上網」，要讓病患、民眾無知暴露於「WiFi無線上網電磁波」下，無知長時間”吃”「無形的塑化劑」(電磁波)?


二、 「WiFi無線上網」設備如同小型基地台，其發出射頻電磁波為看不到、聞不到、聽不到，但長時間接近暴露之危害性已被認定為2B致癌物，而公車司機長時間暴露，更可能引發身體不適而導致交通事故，萬萬不可!


三、 郝市長為食品專家，認定塑化劑2B致癌物應禁止，卻在世界衛生組織認定射頻電磁輻射為2B致癌物後，還鼓勵「WiFi無線上網」設置，無視電磁波存在，郝市長專業出身，更應確認其安全性，否則郝市長無異「決策害人」。


四、 「WiFi無線上網電磁波」不同於咖啡，雖二者都是2B致癌物，而電磁波有血癌及腦部癌症罹患可能，而咖啡，雖IARC將其歸類於2B，但其僅屬膀胱致癌性(喝大量)，其他器官致癌性不屬於2B，人類非24小時喝咖啡或吃塑化劑，但卻有可能長時間暴露於電磁輻射，故不能拿咖啡致癌性與電磁輻射相比。

WiFi in schools proven dangerous.

Microwave radiation dangers in your home

Uploaded by magdahavas on Oct 19, 2010

Magda Havas demonstrates how WiFi connects your laptop, iPhone and iPad to the internet via microwave radiation. You will also learn how WiFi base stations, portable phones and baby monitors constantly radiate microwave radiation. The Swiss Government feels that all of these devices have the potential to do great harm if used incorrectly and warn their citizens.

This is a link to the web page that has additional information.

While the rest of the world rushes onwards with the wireless revolution, Switzerland -- the country that invented the World Wide Web -- and the largest telecom provider -- SWISSCOM which is owned (52%) by the Swiss government - have decided to light up the public school's wired networks using fiber optics FOR FREE!

But there is one catch -- the schools must use LAN -- local area networks. Specifically, the Swisscom application documentation states that the schools pay for the internal wiring and connect their devices (PC, printer) via an Ethernet LAN/10BaseT/RJ45 and then connect it to a Swisscom AG's CISCO router on site. Swisscom then brings the fiber optic connection to the school.

Most schools in North America are opting for a WiFI wireless local area network (WLAN) that allows computers and laptops to be connected to each other without wires. But the Swiss government prefers -- LAN -- wired networks that do not emit microwave radiation. For example, on their public health website, they specifically warn about the dangers of WiFi:

"Only switch your WLAN (WiFi) on when you need it. With laptops, in particular, it is a good idea to switch the WLAN (WiFi) off as otherwise the device will repeatedly try to connect to a network, leading to unnecessary radiation...and caution should be exercised primarily when using devices held close to the body, such as laptops, PDAs and Internet telephones".

「手機上網」電磁輻射，安全嗎?

台灣電磁輻射公害防治協會記者會新聞稿 2011/3/31


「手機上網」電磁輻射，安全嗎?

99%民眾不知手機SAR值、NCC應要求業者標示SAR值於手機上

「手機上網」電磁輻射，安全嗎? 雖至今危害與否仍無定論，但因世界衛生組織已有長久使用手機腦瘤危害發現(世界衛生組織實況報導第193號)，故今天由台灣電磁輻射公害防治協會理事長陳椒華及田秋堇立法委員共同召開記者會提出警告，呼籲重視「手機上網」電磁輻射的安全問題，呼籲不使用時手機勿繼續上網，以免暴露過多電磁輻射。而且要求NCC應要求業者手機明顯標示SAR值，以提供消費者選購安全手機參考。今天記者會也由經常使用手機上網的何宗勳理事現身說法，示範手機上網可能受到的電磁輻射暴露及可能的危害。

一、手機上網有電磁輻射嗎? 答案: 有

本會檢測各廠牌92支手機，皆測到電磁輻射(表二)，其中最高達30 W/m2，而手機上網的電磁輻射值普遍為 數十 mW/m2。

二、手機上網應離多遠可以較少暴露於電磁輻射? 答案: 30~40公分

根據世界衛生組織實況報導第193號(2010年5月)，手機打開時才傳輸功率。隨著手機傳輸距離不斷加長，功率（以及用戶射頻輻射接觸量）迅速衰減。因此，與身體保持30-40公分距離使用行動電話者，如發送短信、上網或使用“免提”裝置(喇叭或耳機)，射頻場接觸量會大大低於把手機放在耳邊接聽者。

三、常用手機上網有危害嗎? 答案: 可能

根據世界衛生組織實況報導第193號(2010年5月)，國際癌症研究機構協調組織了一項名為INTERPHONE的回顧性病例對照研究，目的是探討成年人使用行動電話是否與頭部、頸部癌症有關聯性。13個參加研究國家的資料匯總分析表明，使用行動電話10年以上者，雖未發現罹患膠質瘤和腦膜瘤的風險增加，但一些跡象顯示在10%行動電話累計時間最長使用者中，顯示罹患膠質瘤的風險增加。除此之外，本會也建議有心臟疾病者，應注意避免長時間利用手機上網或將手機靠近心臟及生殖系統。

四、NCC訂定”安全手機或低SAR值標示”嗎? 答案: 沒有

本會針對手機SAR值標示進行問卷調查，回收有效問卷448份(表一)，其中97%不知道手機之SAR值 (W/Kg) 為電磁波能量吸收比值，德國SAR值低者(小於0.6 W/Kg)可以貼上”藍天使標章”， 99%不知道自己的手機SAR值 (W/Kg)為多少? 99%贊成手機SAR值應標在手機醒目位置，如手機背面電磁蓋上面，購買手機時可參考。本會要求NCC也應比照辦理。

SAR值說明:

SAR(specific absorption rate)值 (W/Kg) 為電磁波能量特定吸收率。國內的手機發射強度標準乃依循美國聯邦通訊委員會(Federal Communications Commission, FCC)所訂的特定吸收率SAR值，為1.6 W/kg。德國藍天使標章規範SAR值為0.6 W/kg。2007年出版之電磁波Bioinitiative報告，學者建議SAR值應降為 0.1 W/kg。目前經濟部標準檢驗局並未要求廠商手機需標示SAR值，至今也無經驗可評估SAR值(1.6 W/kg)標準是否適合防護可能的健康風險。

黃泉安所指處為檳城免費無線網絡介入器，只要關閉建築物電源，它便停止操作。（圖：星洲日報）

（檳城18日訊）檳州政府推出檳城無線網絡投訴熱線電話04-6421591，以便負責的REDtone通訊公司可以協助解決人們無法上網的問題。

檳城免費無線網絡幕後推手國會議員黃泉安昨日（18日）在新聞發佈會上說，有關熱線電話將取得“公民監督”，和回饋用戶經驗的功能。

上網若遇障礙
須提供詳細資料

人們尋求檳城無線上網服務面對障礙進行投訴，必須提供發生障礙的地點、時段、大致情況等資料。

他說，有時問題可能出在用戶所在的地點並非檳城無線上網熱點據點，或遠離據點，見到的是流浪無線訊號（Stray Wireless Signals），無法接通。

他說，有時用戶身在熱點據點，可是涉及的無線上網介入器所在的建築物電源關閉，由於沒有電源而停止服務。
他說，有時問題出在用戶使用的是舊式手提電腦，或舊式手機，追不上它的要求，有時問題出在新的操作版本無法和它相容，如智慧式手機或電腦的FLASH版本不受支撐。

每隔15分鐘會自動斷線

他說，檳城免費無線網絡也有自動斷線的設立，每隔15分鐘便中斷，必須重新登錄，世界上的許多大城市免費無線網絡都有這種自動設定。他說，人們必須登記成為檳城免費無線網絡的註冊用戶，才能享有服務。人們也可以上http://www.pdctelco.com.my或http://www.redtone.com查詢。

針對胡棟強投訴不能免費上網
吉寧萬山無網絡介入器

針對檳州民青團團長胡棟強在報章上投訴，在吉寧萬山附近的新街無法通過檳城免費無線網絡上網，黃泉安說，當地不是熱線據點，沒有任何免費無線網絡介入器。

WORLD HEALTH Urgently Needs lower EMF Standards

PRESS RELEASE of the International EMF Alliance, 3 Feb 2011

New International EMF Alliance Announces far-reaching Acientific Consensus Statement, Published Today:
WORLD HEALTH Urgently Needs lower EMF Standards

Oslo, Norway, February 3, 2011. The International EMF Alliance (IEMFA) today announces a new published report and scientific Consensus Statement concerning health hazards of electromagnetic fields (EMFs). Led by Olle Johansson, PhD of the Karolinska Institute, the report published by a consortium of international scientists urges global governments to adopt significantly lower human exposure standards for electromagnetic fields. The recommendations are based on the latest body of evidence in biological sciences, and the public-health implications of the unprecedented global exposures to electromagnetic fields from telecommunications and electric power technologies. The scientists recommend specific exposure limits for different frequency fields, including microwaves, used in wireless communications, and ELF electric fields and magnetic fields.

According to the international scientists, called the Seletun Scientific Panel, it has become obvious that new, biologically-based public exposure standards are urgently needed to protect long-term public health worldwide. Current public-safety EMF-exposure guidelines used world wide, based on physics models and calculations, currently only protect for damage generated by a heating effect. With respect to prolonged, low-intensity exposures that nowadays frequently occur, but do not have a heating effect, the guidelines, say the scientists, are inadequate and obsolete.

An 18 minutes video of Olle Johansson, PhD of the Karolinska Institute, Chair of IEMFA’s Seletun Scientific Panel that issued the report is available here: http://vimeo.com/18018440

The report and consensus statement, published in the journal Reviews on Environmental Health http://www.ncbi.nlm.nih.gov/pubmed/21268443 include ten Key Points:

1. The global Populations are insufficiently protected, thus currently at Risk;

2. Sensitive Populations are extra vulnerable;

3. Government Actions are urgently warranted now, based on Evidence of serious Disruption to Biological Systems;

4. The Burden of Proof for the Safety of radiation-emitting Technologies should fall on Producers and Providers, not Consumers;

5. EMF Exposures should be reduced in advance of complete Understanding of Mechanisms of Action;

6. The current operative measure of Radiation Risk - the specific absorption rate (SAR) - is inadequate, and misguides on Safety and Health Risks;

7. An international Disease Registry is needed to track Time Trends of the incidence of Illnesses to correlate the Illnesses with Exposures;

8. Pre-market health Testing and Safety Demonstration is needed for all radiation-emitting Technologies;

9. Parity is needed for occupational Exposure Standards, compared to those for the General Public;

10. Persons with Electrohypersensitivity need the classification Functionally Impaired.

The International EMF Alliance has rapidly grown in 2010 into a global collaboration of over fifty health advocacy groups focused on electromagnetic fields (www.iemfa.org). Its principle aim is to disseminate coherent, health-oriented information and advice to the public worldwide on the ever-expanding body of knowledge on biological disruptions observed in living tissues after acute and long-term exposure to non-ionizing electromagnetic fields. The Alliance benefits from the support of a large number of life scientists and medical experts from fifteen countries who collaborate worldwide to address emerging threats to public health.

黃泉安：為民聯加分 無線上網非檳負資產

北馬 2011-01-19 18:36

黃泉安：我和檳州免費上網計劃不會拖累檳州民聯。

（檳城19日訊）檳州政府電訊基設特別工作隊主席黃泉安指出，他本身將以“績效”來證明，他大力推動的“檳州免費無線上網”計劃不會拖累檳州民聯，反而會讓檳州變成一個高速上網的州屬，以配合檳首長林冠英有意把檳城打造為國際城市的步伐。

根據一份中文免費週報的報導，指黃泉安推動的免費無線上網計劃已經“觸礁”，這將會拖累檳州民聯的事項，黃泉安極力否認，他強調，他絕對不是檳州政府的負資產，而且該項免費上網計劃也不會拖累民聯。

“我和檳州免費上網計劃會不會拖累民聯，還是為民聯加分，到了大選，他們就會知道。”

擬引進4G技術

他說，他個人不想針對這個沒有根據的指責做出回應，但將會以行動證明，他推動的這項計劃，將會讓人民受惠，這包括準備在29個民聯中選的州選區中，增加免費上網的熱點。

他指出，目前他準備大力推動兩項計劃，以讓檳城成為一個高速上網的城市，第一，就是將在今年內再增設750個免費上網熱點，把熱點增加至1500個，覆蓋範圍延伸到郊區。

他披露，這全新的750個熱點，將會專注在人口密集的地區，尤其是在民聯中選的州選區安裝，此外，也將會延伸到郊區，讓更多人民受惠。

他披露，第二，他將會協助州政府，引進需付費的高速4G無線上網技術，目前楊忠禮集團屬下的YES公司，有意引進這方面技術。

If WiFi harms trees, what about children?

November 24, 2010.

The debate about WiFi being used in schools continues to escalate as new research from the Netherlands shows that when ash trees are exposed to radiation emitted by WiFi base station antennas, the leaves discolor and gradually die.

The study reported that 70% of all trees in urban areas (but not those in dense forests) show the symptoms, compared to 10% five years ago. Although this is a preliminary study, which has not yet been published, it should be taken seriously.
Wageningen University was commissioned by the municipality of Alphen aan den Rijn to determine if electromagnetic radiation from cell phone towers or WiFi masts could play a role in the deteriorating health of the city’s ash trees.



For the experiment, six WiFi access points where erected at various distances from the trees that were continuously exposed for more than three months. The frequency was 2.4 GHz (WiFi) with a power output of 100 mW EIRP, which is the maximum power allowed for use by portable laptop computers. Leaves that were two feet from the WiFI access point developed a metallic luster appearance, a discoloration of the leaves that appeared to result in the disappearance of the outer cell layer of the leaves. The metallic luster was then followed by desiccation and death of a portion of the leaf.

If three months of exposure to WiFi microwaves adversely affects the leaves of trees what is it doing to the growing bodies of children who sit for hours each day in school two feet away from a WiFi enabled laptop computer or a ceiling mounted WiFi access point?

Recent studies show low level Radio Frequency (RF) harm Aspen trees

Aspen decline has been reported in North America over the past half century and rapid mortality of aspen clones has been observed in Colorado since 2004 and has become a major concern for environmentalists, scientists, and foresters.

In one experiment, published February 2010 in The International Journal of Forestry Research, scientists constructed mock-shielded cages and faraday-shielded cages in the forest just outside of Lyons, Colorado. The mock cage shielded aspen seedlings only from direct light – while the faraday cage shielded seedlings from all forms of radio frequency radiation originating from the town of Lyons in the frequency range of 1 MHz to 3 GHz. This includes radio broadcast signals as well as cell phone and WiFi signals.

The researchers discovered that the tree seedlings growing inside the radio frequency-shielded cages were much larger and healthier than those in both the mock-shielded cages and in the unshielded controls.

The authors report that the background levels of radio frequency radiation may be adversely affecting leaf and shoot growth and inhibiting fall production of anthocyanins (these are the pigments associated with leaf senescence in trembling aspen seedlings). These results suggest that exposure to the RF radiation generated by our wireless technology may be an underlying factor in the recent rapid decline of aspen populations.



In the figure above, mock-shielded seedlings on the left and RF-shielded seedlings on the right, the latter showing more total leaf area, stronger fall leaf coloration, and minimal leaf necrosis.



WiFi Smart Meters for “Do It Yourself” home studies

If the electrical utility has recently installed a new wireless Smart Meter on the side of your house, you might be able to do your own plant experiments using simple before and after photography.

Before the smart meter was installed, vibrant green healthy foliage completely surrounded the meter and a robin nested above the meter. Now, the leaves closest to the meter are damaged and the robin is gone.

WiFi 辐射让树木受损,树叶枯死 恐也危害健康

WiFi无线网络越来越普遍，但荷兰研究发现，一些近WiFi网络生长的树木受损、树叶枯死，令WiFi辐射可能有损人体健康亮起警号。

荷兰莱茵河畔阿尔芬市政府，5年前发现当地很多树木树皮和树叶枯萎，于是委托荷兰瓦格宁根大学研究。

研究员疑树木坏死跟辐射有关，因此将20棵白蜡树暴露在距离6种不同来源辐射51公分的位置3个月，结果发现最近WiFi辐射的树，叶子上下两层表皮都枯死，且有70%在城市生长的树都如此。

香港WiFi城市的隐忧

　
加拿大安大略省湖岸大學去年一月全面禁用Wi-Fi。該校傳訊處處長Eleanor S. Abaya回覆本刊指，由於有學生及教師反對使用Wi-Fi，校方遂在教學大樓內的智能課室及機械實驗室加裝寬頻線，鼓勵他們改用有線網絡。校長Fred Gilbert認為，有很多文獻指電磁波可能導致血癌及腦瘤，不希望學生及教師的健康受威脅。

　　英國《星期日獨立報》早前報道，一名教師在學校安裝Wi-Fi後出現頭疼及噁心，懷疑患輻射敏感，校方於是拆除部分發射器。英國教協及獨立組織衛生防護局促請教育大臣調查Wi-Fi會否影響學童健康。

　　英國去年十一月有至少三間學校，拆除Wi-Fi改用有線網絡，認為小童腦殼較薄，神經系統仍在發展，容易被電磁波傷害。各國至今沒有研究針對Wi-Fi對健康所造成的影響。世界衛生組織估計，全球每一百人中有三個對電磁輻射敏感。

台Wi-Fi超標最多350倍

　　在台灣，環保聯盟一月到台大圖書館，測試Wi-Fi無線網絡強度，錄得每平方米三百五十微瓦電磁波。當地環保署、通訊傳播委員會及台大進行同樣測試，每平方米最高達三百三十微瓦，最低為九微瓦。

　　全球對Wi-Fi電磁波仍未有統一安全標準。奧地利訂定的室內安全值是每平方米一微瓦，德國則規定每平方米住宅不可超過五微瓦。台灣的測試結果超出這些標準約二至三百五十倍。

　　聯盟發起「向電磁波說No!」的行動，呼籲市民遠離發射器，又促請所有學校在發射器上貼出告示，提醒學生不宜停留過久。台灣嘉南藥理科技大學副教授陳椒華向本刊記者解釋，長期使用Wi-Fi可能導致頭疼、記憶力衰退、胸悶及脫髮，甚至引發癌症、白血病及孕婦流產，影響中樞神經及生殖系統，市民不應將胸部及腹部靠近電腦，孕婦及小童更不宜使用。

10,000微瓦升1度　影響微
　　香港中文大學社區及家庭醫學系教授余德新表示，Wi-Fi電磁波屬於射頻，對人體產生熱效應：「就像微波爐的微波，過量接觸會增加患白內障的風險，但強度達一萬微瓦，身體組織才會升高一度。」他認為，台灣的測試結果距離最低風險起碼少三十倍，目前仍未有研究證實電磁波會致癌、影響免疫力及神經系統。

　　電訊管理局助理總監陳子儀接受本刊專訪時解釋，本港的Wi-Fi上網熱點平均分布各區，相信電磁波不會太強：「例如發射器會裝置在燈柱較高的位置，離行人起碼十米，危險性不大。」

　　互聯網供應商協會主席莫兆華也指：「除非頭部貼近發射器，否則Wi-Fi的影響遠比手提電話低。」

　　電訊局目前採用國際非電離輻射防護委員會(ICNIRP)，以及美國國家標準學會與電機及電子工程師學會(ANSI/IEEE)的安全標準，監管手提電話發出的電磁波。兩者分別建議人體每公斤最多吸收兩瓦及一點六瓦輻射。

　　工商及科技局發言人回覆本刊表示，會根據ICNIRP守則作指標，在標書中列明承辦商需遵守有關守則。

　　政府年底將會外判公共設施，讓供應商安裝Wi-Fi服務。兩年內，無論室內室外，市民都可使用無線上網。要在燈柱下邊看電郵、邊等朋友，用電子手帳在維園寫網誌，或在登機前到網上聊天室跟朋友道別，都不成問題。

　　目前本港的Wi-Fi市場，由約三十間網絡供應商自行營運。工商及科技局數字顯示，截至二月全港有一千零七十一個熱點，主要在中環、銅鑼灣及油尖旺。市民只要帶同手提電腦或電話，到咖啡室或商場等上網熱點，便可使用收費的Wi-Fi服務。

　　不過，國際機構JiWire的統計顯示，香港的熱點數目在全球排名中十甲不入，輸給台北、首爾和新加坡等。電訊局助理總監陳子儀承認，去年十二月本港舉辦世界電信展期間，Wi-Fi覆蓋面不足，認為「香港要加把勁追上其他城市」。

　　政府為使Wi-Fi達至全城覆蓋，首次在今年預算案撥款在公園、博物館及圖書館等公共場地，提供免費Wi-Fi，又出租市面街燈、路標及天橋予供應商，雙管齊下增設熱點。

街燈遍港九新界

　　政府先開放各區燈柱、橋躉、路標、隧道及交通燈，讓供應商以每年象徵式一元租金安裝Wi-Fi發射器。陳子儀表示，在街燈安裝熱點有助建立全城覆蓋：「港九新界及離島都有燈柱，覆蓋面夠大，又可以供電給發射器。」他估計，要約兩萬個熱點才可覆蓋全港。

　　局方目前收到五宗查詢，其中電訊盈科及香港寬頻兩間供應商已獲發牌，另一宗申請仍在審批。

　　兩大供應商電盈及香港寬頻都對Wi-Fi市場虎視眈眈。前者將在便利店、地鐵、酒店及九間大專院校增設熱點，總數由目前一千三百個加至三千個。後者則投資五千萬元，在酒吧、卡拉OK及部分屋苑電梯大堂，提供Wi-Fi服務。

　　另外，陳子儀指，每個熱點可覆蓋五十至一百米範圍，當局會確保設施不被壟斷：「無須全條街都租給一個人，隔幾支燈裝一個都可覆蓋到。」

業界為主　政府為輔
　　今年預算案其中一項「派錢」措施是撥款二億三千萬元，在三百五十個公共場地提供免費Wi-Fi服務，包括公共圖書館、博物館、文化中心、運動場、大型公園、社區會堂、民政事務總署服務中心，以及部分人流較多的政府部門，如運輸署牌照事務處、入境處人事登記處等。

　　網絡供應商為用戶提供收費Wi-Fi服務，政府卻又計劃提供公共免費Wi-Fi。數碼通總裁黎大鈞曾批評「政府以公帑補貼全世界」，有可能迫使供應商同樣提供免費Wi-Fi服務。

　　但互聯網供應商協會主席莫兆華認為，政府與業界各有空間：「政府只是畫龍點睛，不會覆蓋全港，業界仍可投資私人地方。」他指市場競爭激烈，相信供應商提供的上網速度，會比政府場地快，而業界長遠會靠其他增值服務，經營收費Wi-Fi服務。

　　陳子儀解釋，政府場地未必得到業界垂青：「供應商未必有興趣走入一些偏遠地區，如元朗民政署、坪洲鄉公所等，但政府不可忽略市民的需要。」

官商唱好　用量成疑
　　副政府資訊科技總監麥鴻崧在立法會一個委員會上指，新熱點可以方便市民學習及娛樂，同時有助商人進行電子貿易活動，提升本港形象。

　　不過麥鴻崧強調，此非純粹讓市民上網消遣，相信加裝熱點後會有人上網打機消磨時間。當局會加設過濾及保安軟件，阻止市民進入色情網站，又計劃將服務時間與辦公時間掛勾，例如圖書館晚上關門會同時中斷無線上網。

　　政府與業界紛紛唱好，但有學者質疑市場需求不大。大學聯合電腦中心主任吳南認為，現時Wi-Fi未能打入年青學生市場。港大在三月統計校內Wi-Fi使用率，發現只有一成二學生曾使用過。吳南解釋，校園有足夠電腦設備連接有線網絡，Wi-Fi未算吸引。

　　無線科技商會主席趙志洋也擔心，即使政府大力推動，市民的使用量也未必會高：「如果只有科技，沒有內容，就沒有人用。」他建議供應商為客戶提供多元化服務，如新聞、音樂、電子商貿等服務，以內容留住客戶。「市場個餅非常大，公家私家沒有重疊，但要突圍，就要內容吸引。」

　　 當局五月中會向立法會財委會申請撥款，然後招標，挑選外判商安裝及營運，十一月展開首批工程，預計最快明年六月完成。資訊科技界議員單仲偕認為，政府應先在人流多的地點安裝熱點，並定期評估用量：「裝太多但沒人用，審計署之後又會算賬。」

Wi-Fi Makes Trees Sick, Study Says

Wi-Fi Makes Trees Sick, Study Says

City trees are becoming sick from wireless radiation from local area networks and mobile phones, according to a European study.

By René Schoemaker , IDG News Nov 20, 2010 5:09 am

Radiation from Wi-Fi networks is harmful to trees, causing significant variations in growth, as well as bleeding and fissures in the bark, according to a recent study in the Netherlands.Radiation from Wi-Fi networks is harmful to trees, causing significant variations in growth, as well as bleeding and fissures in the bark, according to a recent study in the Netherlands.

All deciduous trees in the Western world are affected, according to the study by Wageningen University. The city of Alphen aan den Rijn ordered the study five years ago after officials found unexplained abnormalities on trees that couldn't be ascribed to a virus or bacterial infection.

Additional testing found the disease to occur throughout the Western world. In the Netherlands, about 70 percent of all trees in urban areas show the same symptoms, compared with only 10 percent five years ago. Trees in densely forested areas are hardly affected.

Besides the electromagnetic fields created by mobile-phone networks and wireless LANs, ultrafine particles emitted by cars and trucks may also be to blame. These particles are so small they are able to enter the organisms.

The study exposed 20 ash trees to various radiation sources for a period of three months. Trees placed closest to the Wi-Fi radio demonstrated a "lead-like shine" on their leaves that was caused by the dying of the upper and lower epidermis of the leaves. This would eventually result in the death of parts of the leaves. The study also found that Wi-Fi radiation could inhibit the growth of corn cobs.

The researchers urged that further studies were needed to confirm the current results and determine long-term effects of wireless radiation on trees.

快拆線

中国报专栏《四方城》

2010年11月5日

國際著名的環境健康學者蕾薇施博士（Dr Devra Lee Davis）兩個月前出了一本名為《拆線》（Disconnect），講述手提電話對人體健康影響的著作。

曾經是流行病學教授的蕾薇施博士，目前是美國好幾所大學的客卿講師，其中包括了美國的哈佛和喬治市等名校。在其大半生的學術研究和事業裡，積極的投入精神與努力，尤其是環境對於人體健康的重要課題。

《拆線》一書提到，目前全球大約共有40億位手機使用者。這個通常都放在口袋和緊貼耳朵和頭部的通訊儀器，就像極了安置在我們身旁的小型電訊塔，全天候的向我們的身體發射電磁波。更令人擔憂的是，有整20億的手機用戶是20歲以下的青少年和孩童。

蕾薇施博士的《拆線》開始出售時，正好是檳州電磁波輻射公害防護聯盟正在草擬着提呈給大馬通訊與多媒體委員會有關於電磁波輻射的準則、要求與規劃等相關的懸而未決的事項。

手機和無線上網的普及，使到新世紀的全球人類都得面對大量的電磁波輻射的影響。然而，就像美國這樣一個被喻為全球科學與工藝最為先進的國家，對於手機的安全準則令人驚訝和不解的還停留在整30年前的標準。

大馬通訊與多媒體委員會這一次在其官方網站發佈訊息，接受來至於公眾對於電磁波輻射問題的建議，是值得讚賞的。當然，我們更是希望當局是有誠意和魄力去解決，一直以來困擾著人民百姓的電磁波輻射的問題和威脅。

政策的改變和改善需要一股強大的力量！檳州電磁波輻射公害防護聯盟義不容辭的向大馬通訊與多媒體委員會提出具體的建議的同時，更是希望那些如今已經掌權了的火箭諸公，能夠扮演積極、務實和負責任的態度，向有關當局提出他們的意見和看法，包括必要的施壓。

一再延長非法電訊塔寬限期的檳州政府，這一次會總結火箭從在野到在朝對電訊塔和電磁波輻射的經驗，提呈解決方案給當局嗎? 還是會繼續縱容它的蜀中大將放話用煽動法令來抓反電訊塔的人士?

And Now … Tinnitus

June 30

Users of cell phones have another reason to be cautious. An Austrian team has found that the risk of developing tinnitus, a ringing in the ears, doubled after four years. This is one of the first epidemiological studies to investigate the long-term effects of mobile phones on hearing.

Hans-Peter Hutter of the Institute of Environmental Health at the Medical University of Vienna, and coworkers report that the observed association is "unlikely" to be spurious and could have important implications for public health. Their new epidemiological study, based on 100 cases and 100 controls, will appear in an upcoming issue of Occupational and Environmental Medicine.

The "possible association of mobile phone use and tinnitus is plausible," according to Hutter, "because the cochlea [the inner ear] and the auditory pathway are located in an anatomical region where a considerable amount of the power emitted by mobile phones is absorbed." The risk of tinnitus was greatest on the side of the head the phone was used. The doubling of the incidence after long-term use is of borderline statistical significance. Hutter also raises the possibility that other factors may be responsible: For instance, blood flow near the ear could be affected when the user is in a constrained posture while on the phone.

Two large European research projects, GUARD and EMFnEAR, have investigated the possible impact of cell phones on human hearing. But both have focused on short-term exposures —mostly for just 10 or 20 minutes— and have generally found no effects (see, for example, a recent paper in Radiation Research.) These two projects cost a total of $3-4 million.

Michael Kundi, the head of the Vienna institute and a coauthor of the new study, told Microwave News that more studies of long-term exposures and hearing are needed. "It is complete nonsense to look for short-term effects," he said. Kundi explained that the lack of studies on prolonged use of cell phones is not surprising, given the official view that microwaves can only cause heating. "If the position is that thermal effects are all that count, there cannot be long-term effects," he said.

A 2007 study of students in the U.K. found no increase in tinnitus or adverse effects on hearing and balance. Tinnitus is more common among older people.

Dect Phones and Microwave Radiation on the Electrosensitive

magdahavas — March 23, 2010 — Study shows, unequivocally, that microwave radiation from a cordless DECT phone immediately affects the heart causing arrhythmia and tachycardia (irregular and rapid heart rate) at non-thermal levels well below federal guidelines.

WiFi in schools and health effects of microwave radiation

magdahavas — April 27, 2010 — In this video, Trent University professor Dr. Magda Havas and Dr. Fred Gilbert from Lakehead University explain why wireless technologies known as WiFi should not be used in schools because of the known health effects from microwave radiation. Testimonials are also provided by the students of Mountain View School who feel that their ill health could be directly related to microwave radiation emitted by the wireless internet transmission towers that have been installed inside the school.

WiFi concerns at Mountain View School in Collingwood, Ontario, Canada

For distribution:

Hello Everyone,

As some of you already know, there are several students in Mountain
View School in Collingwood, Ontario (Canada) who are complaining about
ill health after the school installed WiFi. Rodney, a concerned
father, invited me to give a talk in the Community this past week and
the room was packed with parents, health care professionals, people
from the community, and the media so I hope it will generate more
interest once the articles begin to appear.

See video clip of interviews with some of the students at the school.

See video documenting tachycardia in adults during provocation with a
cordless (DECT) phone. http://www.youtube.com/watch?v=_EI9fZX4iww

What is disturbing is that several students have complained about ill
health, two students are now on heart medication and one young girl is
scheduled for heart surgery on Monday June 14th. A student in a
Toronto school (also with WiFi) fainted while standing in the hallway
near a WiFi antenna. The students with heart conditions have been
diagnosed with one of the following: vaso vagal syndrome,
supraventicular tachycardia (SVT), or Wolff-Parkinson-White (WPW)
Syndrome (abnormal connections or accessory pathways in the heart) a
form of atrioventricular reciprocating tachycardia (AVRT).

Symptoms for SVT include: dizziness, shortness of breath, chest pain,
a pounding sensation in the throat or neck, weakness, fatigue,
lightheadedness, fainting (especially in the case of underlying heart
disease) and resemble EHS symptoms.

Prevelance rate for tachycardia is about 1.6% to 2% for adults.
http://www.wrongdiagnosis.com/t/tachycardia/stats.htm
Prevelance for WPW is 0.15% in children. See:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2363719/ Epidemiology of
Arrhythmias in Children, by R Prem Sekar. Indian Pacing Electrophysiol
J. 2008 Apr–Jun; 8(Suppl. 1): S8–S13.

I recently heard that all the schools in my district (Kawartha Pine
Ridge) are going to have WiFi installed soon. Where are these schools
getting information that this technology is safe? I find this
situation most disturbing. If these heart conditions are related to
WiFi then I think the schools and those who make the statement that
this radiation is safe (Health Canada and local Health Boards) are
culpable.

Have received emails from several of the people who attended the
presentation this past week and learned that some parents are also
having heart palpitations and rapid heart rate because of WiFi in the
home. They didn't know this was contributing to their heart problems
and have, since the talk, disconnected their wireless devices.

Why are doctors not better informed? Anyone who suddenly experiences
a heart irregularity should be asked some specific questions about
whether or not they have wireless routers, cordless phones, energy
efficient CFL bulbs, nearby cell towers, etc. as routine questioning.

The heart problem (arrhythmia or tachycardia), which can be easily
measured, may be a very important test for those who are EHS. Please
spread the word and ask your friends if they experience symptoms of an
irregular or racing heart and if they do ask them when it started,
what changed at that time, if it is occassional-when they experience
it and what they are doing about it. The more information we can
gather the more impact it is going to have on school boards. Getting
rid of WiFi is more difficult than preventing it from being allowed
into a school in the first place.

Please distribute this email to your friends and let's get a better
understanding as to how widespread this heart problem is and the
degree to which it relates to wireless technology and electrosmog
exposure.

Thanks for your help,
-magda

p.s. If you or someone you know is experiencing heart problems, which
may be related to electrosmog, please contact me with your symptoms
and your experience and send a copy to: info@safeschool.ca
