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。

她每次出門都要從頭到腳包緊緊 因為... (今日新聞 5/7/2015)

 




英國有位 50 歲的女子每次出門都要將自己從頭到腳包緊緊,包得比伊斯蘭教的女子還要密不透風,但她這麼做的理由,卻不是因為宗教因素,而是……。


英國《每日郵報》報導,50 歲的潔姬(Jackie Lindsey)隱居在多塞特郡溫伯恩明斯特(Wimborne)的鄉村中,每天出門都把自己包得密不透風,她自稱患有「電磁波過敏症」(Electromagnetic Hypersensitivity, EHS),只要感受到電波就會渾身不對勁,嚴重的話還會導致過敏性休克。她宣稱:「怕怕Wi-Fi殺了我」。

潔姬每次出門時,都會以灰白色的面紗層層包裹住全身,這些遮擋的面紗纖維中,有20%的銀色編織物可以用來反射電磁波的磁場。她說自己穿這樣出門時,看到的人都會以為她是得了什麼高傳染性的疾病,還有人形容她的裝扮像是一名「瘋狂的養蜂人」。

潔姬丟掉了家中所有的電器用品,僅用蠟燭替代燈光,用瓦斯烹煮、加熱食物。她還為了要躲避鄰居的電磁波,在8年前賣掉房子,搬到空曠的鄉下居住。

「電磁波過敏症」目前仍未被英國的醫學界承認,但在瑞典已被列為醫學症狀之一。

手機輻射勁 iPhone6 Plus高5倍 (蘋果日報 2015/03/18)

據《蘋果日報》報導,香港的智能手機普及率全世界排名前列,惟手機釋出的輻射卻有可能致癌。《蘋果》早前委託本地大學為六款熱門智能手機進行測試,發現蘋果iPhone6 plus通話時釋出的輻射較其他測試品牌高逾五倍。有用家坦言將iPhone貼身存放時皮膚會感到灼痛,懷疑與輻射有關。

世界衞生組織早於2011年將手機釋出的電磁波輻射歸類為「2B級致癌物」,有可能對人體致癌;至於量度手機輻射,則以人體實際吸收的射頻能量水平、即「比吸收率(SAR)」為標準。

蘋果日報早前委託本地一間大學的實驗室為蘋果iPhone6、iPhone6 plus、HTC Desire Eye、Samsung Note4、Note Edge及Huawei Mate7等共六款熱門智能手機,進行比吸收率測試。測試期間,實驗室人員以儀器測試處於通話狀態的手機,計算一般用家在使用手機通話時,頭部會吸收到多少電磁波輻射。

結果發現,深受港人歡迎的蘋果iPhone6 plus,其比吸收率數值為0.58瓦特,屬六款測試手機中最高;至於機身呎吋較少的iPhone6也不惶多讓,錄得0.27瓦特,屬第二高。餘下四款手機的比吸收率則平均只有0.1至0.15瓦特,最低的是Huawei Mate7,只有0.102瓦特,以此計算,蘋果手機的輻射量可較其他手機高逾五倍。

根據通訊辦規定,在香港出售的手機必需符合國際非電離輻射保護委員會(ICNIRP)建議,即比吸收率不可超過2瓦特,是次測試的所有手機均未有超標。惟有iPhone6 plus用家透露,曾將手機放在腰間手機袋,半日後隨即感到袋下的皮膚及內臟灼痛,直至取走手機才回復正常,懷疑與輻射有關。「一年前出國旅行借過一個4G Wifi蛋放喺袋,過咗陣背脊皮膚灼痛,要拎走個Wifi蛋,等多幾個字先冇事。」

內科腫瘤專科醫生邵祖德指,長時間接觸高能量的電磁波輻射,會影響人體細胞,「細胞入面嘅基因物質,本身有電子...電波會影響佢運行,細胞基因有機會不穩定,尤其係大腦,輕則可能影響注意力、記憶力及精神,嚴重啲令基因造成永恆突變,造成癌變。」至於要承受多少劑量才造成此後果,至今還未有定論。

他又指,部份抵抗力較弱人士,或較易受手機的電磁波輻射影響,因皮膚下的神經線受刺激引起觸電般痛楚。「呢啲都唔係太大問題,最驚都係對腦部有影響。」

香港資訊科技商會榮譽會長方保僑指,只要手機本身天線設計等接收能力夠強,又或機身設計較好,便可減低手機釋出的電磁波輻射,「好似車咁,大家可以有同樣馬力,但係一部食油啲一部慳油啲。」他又指,部份廠商會較重視產品的比吸收率,相對付出較多資源降低輻射量;也有部份廠商只要求符合法例要求便覺充夠,「好似環保咁,大家願意投放落去嘅資源都唔同。」

日煲手機6小時 英商人患腦癌 (晴報 2015/02/26)


據【晴報專訊】報導,英國一名因工作每日講手提電話達六小時的男商人,早前發現右耳生腦瘤,證實罹患癌症,只餘下三年壽命。他認為致癌與「煲粥」太多有關。

英國《每日郵報》報道,現年43歲的菲臘斯於一間醫療公司任職營運經理,年薪132萬港元,工作離不開手機,有時更開電話會議長達2小時,每月通電話超過100小時。

他早前感覺頭部常出現劇痛,到醫院做檢查後證實右耳長有第三期惡性腫瘤,雖然他接受手術移除部分腫瘤,但醫生告知他腦癌無法根治,只剩下三年壽命,叫他好好享受餘下時光。

右耳長瘤剩三年命

菲臘斯信患癌與長期使用手機有關:「每當我收工時,右耳都會發紅。我當時沒意識到有毛病。」他已辭工接受化療,又成立慈善基金會,呼籲公眾關注長期使用手機的健康風險。
