案情接近水落石出 (晴報-嚴浩專欄 1/11/2016 )

按德國建築生物學院(IBN)的標準,睡眠環境中的電磁波如超過100微瓦,已屬極強干擾,長遠會危害中樞神經系統、免疫系統、心血管系統、血液系統、視覺系統,以及可能致癌。前文的患者在床頭腦袋旁邊安放了一台無綫電話超過十年,無綫電話所產生的電磁波輻射約250毫瓦,已經超過100微瓦極強干擾底綫的2,500倍,他的健康會好嗎?

現代人很多有睡眠問題甚至健康問題,有幾個人明白是電磁波輻射的影響?因為這樣,前文中的患者逐漸有嚴重的睡眠問題、頭痛、嚴重鼻敏感以致失去嗅覺、耳鳴、不論春夏四肢末端冰冷……這些徵狀的出現是有次序的:開始的時候是睡眠障礙、頭痛、鼻敏感,然後才耳鳴。這個先後次序我特意向患者求證,他回憶了很久以後確認了。

通訊系統所產生的人為電磁波,在大自然環境裏本來是沒有的,但已日益增多而且頻率愈來愈高。令人擔憂的是,電磁波對人類與動物的危害還未得到社會重視,受害者都是有苦自己知。在本案例中,電磁波破壞腦部神經,波及顱底嗅覺神經,出現鼻炎(鼻敏感)。鼻炎多數不影響耳鳴,但鼻炎會引起顱內的繼發感染,一旦顱內感染發生的話,就有可能引起耳鳴

生物共振測試也提醒同一位患者,他可能嚴重缺乏酵素。甚麼是酵素?缺乏酵素如何影響我們的身體健康?人體本來有自行製造酵素的功能,為何會缺乏?是飲食不健康嗎?但患者平時已經十分注意飲食均勻。

酵素也稱為酶,是一切生命的開始;沒有酵素,體內大部分活動就會停擺,維持生命的體內新陳代謝會停頓,脂肪、蛋白質、澱粉等無法分解、消化和吸收。

超過危險底綫2500倍 (晴報-嚴浩專欄 31/10/2016 )

2015年2月10日,我在《晴報》本欄特別針對室內無綫電話對健康的危害作了第二次報道:「我在上個月初的專欄中曾經這樣報道過,匈牙利的生物物理教授András Varga博士做了一個實驗,將孵化期的雞蛋每天暴露在0.9毫瓦功率(0.9mW)的高頻電磁輻射下幾個小時,結果,孵化出的小雞當中出現了四種畸形現象:向內扭曲的爪、畸形的肋骨、畸形的喙部和有缺陷的眼睛。」

這0.9毫瓦功率的輻射難道是來自一個高強度的電磁波發射器?非也!以下是一些數據:「家用室內無綫電話(cordless phone)所產生的電磁波輻射約250毫瓦,手機在待用狀態的發射功率約為3毫瓦,但通話時竟高達800毫瓦!在公眾Wi-Fi發射點中,發射功率可以達到5,000毫瓦至10,000毫瓦!」
在繼續重溫我在一年多前,針對電磁波和室內無綫電話危害健康的報道前,先了解一道簡單的數學題:一毫瓦等於1,000微瓦,有了這個量的概念後,我們繼續閱讀這篇快兩年前的文章。

「本地媒體在2012年11月報道:『近年有研究報告指,當室內電磁波達每平方米3,000、4,000微瓦,患癌機率就增加四倍多;數十至數百微瓦已可引致不適徵狀。按德國建築生物學院(IBN)的標準,睡眠環境如超過100微瓦已屬極強干擾,長遠會危害中樞神經系統、免疫系統、心血管系統、血液系統、視覺系統,以及可能致癌。即使是室內,石屎牆阻隔了部分電磁波,但如有發射站對正、甚至前後夾擊的話,電磁波仍然可能『爆錶』。」
睡眠環境如超過100微瓦已屬極強的干擾,而家用室內無綫電話所產生的電磁波輻射約250毫瓦!一毫瓦等於1,000微瓦,超標接近2500倍!

與殺手同眠十多年 (晴報-嚴浩專欄 28/10/2016)

生物共振測試的其中一個功能,是提醒測試者生活環境中可能有其他的因素影響健康,譬如「電磁波影響」以及「地理壓力影響」:電磁波影響來自現代的電子產品,譬如手機、Wi-Fi、充電器、室內無綫電話、窗外手機發射站、高壓綫等;地理壓力則來自地球網格,詳細內容請參考我的書。

不是每一個家庭或者每一個人都會受這些看不見的因素影響,即使受影響,程度也大小不一;但如果比較嚴重,就有可能出現各種疾病,這些病形形色色,但有一個共同點:引起病徵的原因不明。患者除非處理了生活環境中不利健康的源頭,否則用甚麼方法也治不好。

這與前文讀者的問題一樣,醫生說他的腦血管有雜質,也同樣診斷為病因不明。患者做生物共振測試,提醒他可能有腦部周邊神經不平衡,因此影響了嗅覺神經,同時也進一步提醒:患者受到嚴重的電磁波影響。人對電磁波沒有熱的感覺,以為對健康沒有影響,但根據科學家的最新研究,知道電磁波是通過輻射影響人體細胞之間鈣通道的運作,從而引起可以致命的健康危機,這個報道我曾經在一年前通過專欄跟大家分享,也已經收錄在我的新書之中。

至此,患者回顧臥室的電器擺設,赫然醒悟床頭安置了一台室內無綫電話,時間已經超過十年!這十多年來,他的睡眠愈來愈差,鼻敏感嚴重到完全失去嗅覺,又有耳鳴,不論春夏四肢末端冰冷……室內無綫電話發射的電磁波真的對健康有這麼嚴重的破壞性嗎?本文是否有馬後炮之嫌?後文將是一年多前,2015年2月10日,我在本專欄特別針對室內無綫電話(cordless phone)的第二次報道。

中正教授籲:別讓電磁波謀殺健康 (台灣聯合新聞網 20/10/2016)

彰化縣田尾、北斗、田中、社頭反超高壓電自救會昨天舉辦抗爭台電八周年紀念會,自救會成員陳文雄教授也發表新書「來自空中的殺手,別讓電磁波謀殺你的健康」,陳文雄呼籲台電要正視高壓電及電磁波對民眾健康威脅,加強監控高壓電或地下電纜的電磁波,民眾也可設鋁板等擋電磁波危害。

中正大學特聘教授陳文雄說,2007年他剛從美國俄亥俄州立大學退休,正高興可以回到家鄉彰化田尾鄉過無憂的退休生活,沒想到台電正要興建南投一彰林345KV超高壓輸電線,為免電磁波危害健康,他只得和大家一起投入抗爭設高壓電塔的行列,雖然超高壓輸電線還是在三年前完成了,他們的抗爭失敗,但民眾在電磁波的危害下並沒有解除,所以他希望出書,疾呼大家重視電磁波危害健康問題。

學界、醫界都懷疑極低頻電磁波和腦瘤、乳癌等各種癌症及失眠有關,而進行研究,陳文雄說,政府所訂定的833毫高斯環境建議值常被台電拿來當極低頻電磁波的安全標準根本不對,早就應該修正這樣的建議值,在德國的安全住宅標準是1毫高斯,在台灣若超過4毫高斯應該就有危害健康風險。

近年來民眾經常抗議設變電所、高壓電纜、甚至地下電纜,陳文雄甚至進行調查,有些人罹癌、長期頭痛,和電磁波有關,他也建議台電若埋地下電纜應比照日本埋在6公尺深,而非是台電現今只埋1.5公尺深。

陳文雄也呼籲民眾也要正視自己使用微波爐等電器用品、及手機的電磁波危害。

台電彰化區營業處副處長陳華信表示,一般吹風機可能就有好幾百毫高斯的電磁波,一般變電所大約只有幾十毫高斯,目前高壓電纜線是埋在1點2公尺以下,是為了避免重車重壓破壞,距離地面這麼遠,應能有效隔絕電磁波。

用WhatsApp LINE講電話 電磁波升6萬倍? (蘋果日報 10/7/2016)

手機通訊app都有通話功能,包括WhatsApp、LINE,喺海外可以免費打電話畀屋企人,慳好多電話費,但有時唔一定打長途,朋友會錯手打WhatsApp電話畀你,又或者有啲人覺得用WhatsApp被截聽機會細啲...(你唔係以為香港冇電話竊聽呀嘛)。

不過,最近網絡尤其台灣流傳「通訊軟體打電話 電磁波瞬間飆高6萬倍!」,當地東森新聞【網事有影嘸】仲搵專家做測試,發現手機備用時,電磁波係320微瓦,普通打電話升到最高9.2萬微瓦,但用Line打電話,會狂升到32萬微瓦,係備用狀態嘅1,000倍。升6萬倍係流嘅?專家話未必,因為如喺辦公室、交通工具,好多人一齊用LINE打電話就有咁嘅可能。

其實2013年,台灣電磁輻射公害防治協會已經用三星、SONY、hTC、iPhone、SHARP等手機測試用LINE時產生嘅電磁波,發現用邊款手機,電磁波都係唔使手機時嘅5至6萬倍。協會話,據世衛調查約有3%至5%人,可能對電磁波敏感,會覺得攰、頭暈、耳鳴、失眠、頭痛等。如必須用軟件打電話,通話時間愈短愈好,最好用無線耳機,否則手機都要距離耳仔最少2cm。

當地台南大學生態科技學系教授兼主任鄭先祐話,用其他app如WhatsApp都係一樣,因手機訊號都會提升,希望令到app運行更順暢,所以電磁波就會升高。
手機電磁波係咪危害健康仲未有證據,但凡事適可而止,用手機講太耐電話都手軟頸痛啦。(喂呀,用手機睇埋呢篇先啦)

別再低頭了!美證實手機電磁波致癌 (台灣東森新聞 28/5/2016)




手機是現代人的必備用品,尤其是有了智慧型手機後,縮短了人與人之間的距離,更是機不離身。但,手機的電磁波是否會致癌?這個問題多年來爭論不休,人們說手機不會致癌,提出會致癌的學者也都因為樣本不足而備受質疑,但現在美國學者斥資2500萬美元(8.1億台幣)研究,將推翻手機不會致癌的說法。

根據美國國立衛生研究院(NIH)監督的國家毒理學計劃(National Toxicology Program)的最新研究,動物實驗證實,手機放射的電磁波確實會造成癌症。國家毒理學計畫花了2年時間,將超過2500隻公老鼠曝露在手機頻率的電磁波之中,發現接受過照射的老鼠,有許多長出腦神經膠質瘤,或者是心臟神經鞘瘤。相反的,其他的老鼠則沒有出現病症。

這份研究是自1990年有手機電磁波致癌的疑慮開始,至今最浩大以及最深入的研究,國家毒理學計劃前研究人員曼尼克(Ron Melnick)接受《華爾街日報》訪問時指出,人們說手機沒有致癌風險,這份研究終結了那種說詞。

Cell Phone Radiation Boosts Cancer Rates in Animals (Microwave News 25/5/2016)

Cell Phone Radiation Boosts Cancer Rates in Animals;
$25 Million NTP Study Finds Brain Tumors

U.S. Government Expected To Advise Public of Health Risk


The cell phone cancer controversy will never be the same again.

The U.S. National Toxicology Program (NTP) is expected to issue a public announcement that cell phone radiation presents a cancer risk for humans. The move comes soon after its recently completed study showed statistically significant increases in cancer among rats that had been exposed to GSM or CDMA signals for two-years.

Discussions are currently underway among federal agencies on how to inform the public about the new findings. NTP senior managers believe that these results should be released as soon as possible because just about everyone is exposed to wireless radiation all the time and therefore everyone is potentially at risk.

The new results contradict the conventional wisdom, advanced by doctors, biologists, physicists, epidemiologists, engineers, journalists and government officials, among other pundits, that such effects are impossible. This view is based, in part, on the lack of an established mechanism for RF radiation from cell phones to induce cancer. For instance, earlier this week (May 22), a medical doctor in Michigan wrote an opinion piece for the Wall Street Journal stating that, “There is no known mechanism by which mobile phones might cause brain tumors.” He went on to argue that there is no need to warn the public about health risks.

The NTP findings show that as the intensity of the radiation increased, so did the incidence of cancer among the rats. “There was a significant dose-response relationship,” a reliable source, who has been briefed on the results, told Microwave News. No effect was seen among mice. The source asked that his/her name not be used since the NTP has not yet made a formal announcement. The rats were exposed to three different exposure levels (1.5, 3 and 6 W/Kg, whole body exposures ) and two different types of cell phone radiation, GSM and CDMA.


An Amazing Coincidence?

Importantly, the exposed rats were found to have higher rates of two types of cancers: glioma, a tumor of the glial cells in the brain, and malignant schwannoma of the heart, a very rare tumor. None of the unexposed control rats developed either type of tumor.

A number of epidemiological studies have linked cell phones to both gliomas and to Schwann cell tumors. The Interphone study, for instance, found an association between the use of cell phones and gliomas.

The sheath that wraps around cranial nerves —such as the one that connects the inner ear to the brain— is made of Schwann cells. Tumors of those cells are called acoustic neuromas. That is, an acoustic neuroma is a type of Schwannoma. At least four different epidemiological studies have found an association between the use of cell phones and acoustic neuromas.

Ron Melnick, who led the team that designed the NTP study and who is now retired, confirmed the general outline of the results detailed by the confidential source. “The NTP tested the hypothesis that cell phone radiation could not cause health effects and that hypothesis has now been disproved,” he said in a telephone interview. “The experiment has been done and, after extensive reviews, the consensus is that there was a carcinogenic effect.”

“These data redefine the cell phone radiation controversy,” Melnick said. The safety of cell phones has been debated for more than 20 years, especially after the International Agency for Research on Cancer (IARC) classified RF radiation as a possible human carcinogen in 2011.

“This is a major public health concern because the cells which became cancerous in the rats were the same types of cells as those that have been reported to develop into tumors in cell phone epidemiological studies,” Melnick added. “For this to be a chance coincidence would be truly amazing.”

The NTP radiation project, which has been underway for more than a decade, is the most expensive ever undertaken by the toxicology program. More than $25 million has been spent so far.

Another interesting coincidence is that the Ramazzini study of rats in Bologna exposed to extremely low frequency (50 Hz) EMFs also developed a significant increase in malignant schwannoma of the heart.


NTP Stands By the Study Results

Because of the importance of these results to public health, the NTP alerted the highest levels of the National Institutes of Health (NIH), where resistance prompted further reviews. No serious flaws in the data or the conduct of the studies were identified.

Senior managers including Linda Birnbaum, the director of the National Institute of Environmental Health Sciences (NIEHS) who also serves as the director of the NTP, and John Bucher, the associate director of the NTP, who is in charge of the cell phone study, are standing by the study findings. They see the need to release the results as a public health imperative, according to the source.

Chris Portier, who once held Bucher’s job, agrees that the NTP is doing the right thing. “I would be adamant that we should share the data with the public as soon as possible,” he said in an interview. The cell phone study was initiated while Portier was serving as the associate director of the NTP. He is now retired, though he continues to work as a consultant.

After extended discussions, the two federal agencies responsible for regulating exposures to cell phone radiation, the Food and Drug Administration (FDA) and the Federal Communications Commission (FCC), were briefed on the results last week. It is not clear how these regulatory agencies plan to respond.

All the various agencies are now in the process of planning the release of the NTP findings. Neither Birnbaum nor Bucher responded to a request for comment on how this will be done.


Unexpected Findings

Few outsiders are yet aware of the NTP results. When Microwave News told some of those who have been tracking the study for years what had been found, all expressed surprise.

Indeed, in an interview published years ago, NTP’s Bucher said that he expected the results to show no association between RF radiation and cancer.

“Everyone expected this study to be negative,” said a senior government radiation official, who asked that his name not be used. “Assuming that the exposures were carried out in a way that heating effects can be ruled out, then those who say that such effects found are impossible are wrong,” the official said. (The study was designed to ensure that the body temperature of the exposed rats increased less than 1ºC.)

“This is a game changer, there is no question,” said David Carpenter, the director of the Institute for Health and the Environment at the University of Albany. “It confirms what we have been seeing for many years —though now we have evidence in animals as well as in humans.” Carpenter went on to add, “The NTP has the credibility of the federal government. It will be very difficult for the naysayers to deny the association any longer.” Carpenter’s institute is a collaborating center of the World Health Organization (WHO).

John Boice, the president of the National Council on Radiation Protection and Measurements (NCRP), is one of the leading skeptics. “For most of us, the issue of brain cancer and cell phones is resolved. There is no risk. There is no biological mechanism and no animal study or cellular study that finds reproducible evidence of an effect,” Boice told a reporter for Medscape Medical News earlier this month.

This view is so deeply held that in the summer of 2014, the NCRP pressured the Centers for Disease Control (CDC) to delete precautionary advice from a fact sheet on cell phones.

Boice was discounting last year’s report from Germany by Alex Lerchl confirming an earlier animal study showing that cell phone radiation can promote tumors in mice that were induced by toxic chemicals. The NTP experiments did not use any agent to initiate cancer cells in the animals.

With respect to mechanisms, just a couple of months ago, Frank Barnes and Ben Greenebaum, two senior members of the RF research community, announced that they could explain how low levels of RF radiation could alter the growth rates of cancer cells.

公屋天台基站密如插針長刺居民 (東方日報 2/3/2016)

牛頭角下邨被測出每平方米電磁波功率密度逾一萬四千微瓦。


據《東方日報》報導,房屋署零諮詢,為賺錢狂加基站!本港流動通訊發射站(簡稱基站)密度高,除私人屋苑及村屋外,房署亦將近千個基站裝置設於公共屋邨天台,當中觀塘牛頭角下邨便有四個基站,有住戶多年來飽受頭暈及頭痛之苦,有專家更測出該邨電磁波功率超出德國健康住宅規範十三倍。黃大仙沙田坳邨亦被測得超出七倍,居民曾群起反對建基站,房署仍充耳不聞。然而,該些基站去年為房委會帶來逾一億六千萬元進帳,立法會議員批評房署對有關收益常含糊其詞,似是掩飾將私益建築於居民痛苦上的事實。

「由一四年五月到依家每日都覺得頭暈,有時頭痛,好唔舒服,日間更不自覺會磨牙。」居住於牛頭角下邨貴亮樓高層單位、六十多歲的李女士於一三年一月搬入該單位,其中一支信號收發裝置正正安裝在其單位「頭上」,附近亦有兩支。由於李每日在屋內逗留近二十小時,梳化床亦放置在窗旁,「無論睇電視定瞓覺,都會對住基站。」李認為長期不適與基站發出的電磁波有關,曾向房署投訴,惟最終不了了之。

李仕沖指,沙田坳邨每平方米電磁波功率密度達八千九百一十六微瓦。


頭痛頭暈 冇覺好瞓

另外,沙田坳邨居民陳小姐(化名)亦指,去年底發現居所天台開始加裝多支信號收發裝置,當時全層居民曾聯署去函房署反對,但房署未有理會,更不斷增加,「(我)同老公(住喺度)會覺得成日頭痛而痛醒,都擔心影響健康。」

按房委會資料顯示,截至去年十一月底,設於房委會轄下物業的電訊裝置總數有一千零四十七個,而每個發射基站和天線每月最低收費為一萬一千元,去年為房委會帶來一億六千二百六十萬元,而房委會更建議一六至一七年度把收費上調,增幅由百分之三點六至百分之五點六不等,未來一年收入將增加至一億六千九百二十萬元。

本港電磁波輻射水平不斷飆升,惟目前本港仍採用「國際非電離輻射防護委員會」(ICNIRP)制訂的非電離輻射限值,於各常用移動通訊頻率,由每平方米四百萬至一千零五十萬微瓦不等。反觀內地「電磁輻射防護規定」,相應頻率的標準僅為每平方米不得超過四十萬微瓦,兩者相距甚大。另外,根據德國的健康住宅規範SBM-2008列明,每平方米電磁波功率密度高於一千微瓦,屬於「極嚴重」情況,需立即改善。

將軍澳怡明邨大廈天台有多支信號收發裝置。


超出德國規範13倍

數年前成立「電磁波日記」的家居易技術總監李仕沖一直監測本港電磁波,日前李透過電磁波測試計,發現牛頭角下邨每平方米電磁波功率密度達一萬四千四百四十一微瓦,超出德國規範十三倍;而沙田坳邨每平方米電磁波功率密度達八千九百一十六微瓦,亦超出七倍。「度出嚟嘅電磁波功率明顯係由邨內嘅電基站發出,會令人頭暈、頭痛,影響人體。」李直指,牛頭角下邨鄰近九龍灣,由於人口密集,故發出的電磁波功率或較其他地方大。

吸收過量損害細胞

香港大學電機電子工程系副教授張星煒表示,本港採用的非電離輻射限值很高,在不同地方測試也難以超出標準。而人體吸收過量電磁波有可能損害細胞。另外,內科腫瘤專科醫生邵祖德指,居民感頭暈及頭痛,不排除與電磁波有關。

房委會發言人表示,營辦商需就安裝於上述公共屋邨天台的電訊裝置繳付市值暫准證費,釐定有關收費時會參考私人市場相類似裝置的租金資料,而有關暫准證費用或租金撥入商業樓宇運作帳目,與現行公屋租金調整機制並無關係。而基站裝置的數目會視乎營辦商和整體的需求以及其可行性而定。該署過去三年只接獲零星相關投訴。

通訊事務管理局辦公室發言人指,電訊營辦商在批准基站申請時,會就基站發出的非電離輻射水平作評估,而通訊辦亦會定期抽樣巡查及測量已獲批准的基站附近地方的輻射水平。

日玩手機20分鐘 腦生瘤風險飆升3倍 (on.cc 東網 1/8/2015)




都市人經常機不離手,小心隨時患癌症及腦退化。外國科學家最新研究,手機、平板電腦發出的輻射可能威脅健康,輕則頭痛和皮膚過敏,嚴重可增加患癌機會。研究指,每日使用手機20分鐘且持續達5年,患腦腫瘤風險飆升3倍。專家警告,手機輻射對兒童的遺害或更深,提醒市民應減少使用手機時間,或改用免提裝置。

該研究由美國、烏克蘭、芬蘭及巴西4個國家專家負責,回顧分析100份與無線電頻相關研究,對象為使用手機10年以上的成年人。結果發現,手機輻射可令人體造成「氧化壓力」,導致體內氧化與抗氧化作用失衡,損害健康。頭痛、疲勞和皮膚過敏等徵狀,甚至癌症、腦退化症、柏金遜症也可能與長期接觸手機輻射有關

研究顯示,連續5年每日用手機20分鐘,患腦腫瘤風險增加3倍;連續4年每日用手機一小時,患腦腫瘤風險增加3至5倍。世界衞生組織轄下的國際癌症研究所2011年已提出,手機輻射可能致癌,暫無結論。參與上述研究的學者強調,兒童對輻射的反應更加敏感,影響或更嚴重,應關注兒童使用手機的情況。研究結果刊登在《電磁生物學及醫學期刊》。

香港大學腦內科教授張德輝指出,手機輻射屬於一種能量,人體細胞吸收能量或產生少許熱力。理論上熱力或會影響蛋白、酵素及DNA結構。他解釋,身體藉氧化作用提供能量,如將脂肪酸轉化為能量,過程中產生「自由基」。當身體機制失衡,可產生過多「自由基」,出現「氧化壓力」,因而可能誘發基因突變而形成腫瘤。張又說,自由基好活躍,似社交分子咁周圍識人,它黏住DNA而有化學作用,可致DNA變異。

城市大學電子工程學系副教授鄭利明亦稱,手機、平板電腦等流動裝置透過無線電頻收發訊號時會釋放輻射。每遠離無線電頻一呎,輻射量會減半。為減低吸收輻射,他建議勿把手機集中放一點,「換下另一邊耳仔聽」,而質素差的耳筒或引導輻射到身體,應選擇品質較佳的耳筒。而搭升降機使用手機可令輻射量大增,原因是升降機內信號接收差,手機為增強信號,輻射量會提升,手機主人及其他搭客均可吸收輻射。

張德輝補充,雖然手機的輻射量遠較照X光為低,但因不少市民長期使用手機,建議使用免提裝置,減低對腦部影響。他指上述研究主要以統計學分析使用手機與患腦腫瘤的關係,仍需再做研究才能確定兩者是否有關。
