A Report on Non-Ionizing Radiation

News & Comment

Sunday, May 28, 2006

Metal earrings can spark hotter hot spots in the heads of cell phone users. A team of Spanish scientists has found that the peak SAR —a measure of the energy delivered to human tissue— can be up to 25% higher when a 900 MHz phone is pressed up to an ear pierced with a metallic object. In a paper that will appear in a future issue of Bioelectromagnetics, David Sanchez-Hernandez and coworkers at the Polytechnic University of Cartagena don't say exactly where such hot spots may turn up nor whether this type of magnification will also occur with 1800 MHz phones, but they do advise that this finding merits "special attention."

RMIT University has announced that environmental surveys have identified "no anomalies" on the top two floors of the Melbourne building where a cluster of brain tumor cases had been identified (see our May 13 and May 19 posts).

As the investigation of the RMIT University brain tumor cluster continues in Melbourne (see our May 13 post), we are reminded of another cancer cluster, which was also much in the news down under about this time last year. In this earlier case, some ten women working in the Australian Broadcasting Co.'s (ABC) offices in Brisbane developed breast cancer and, as at RMIT, power-frequency EMFs and RF radiation were under suspicion because there were antennas on the roof of the ABC building.

EMC Technologies, a test and measurement consulting company, was called in to survey the entire ABC site. Soon afterwards, ABC Queensland director Chris Wordsworth told the Sydney Morning Herald that testing had shown "nothing adverse." That April, Chris Zombolas, the technical director of EMC Technologies, confirmed to us what Wordsworth had already told the local newspapers: He had not found high levels of any electromagnetic signals. But, Zombolas added, he was not in a position to release the report —that would be up to ABC. Figuring there was nothing much more to the story, we moved on and did not give it much thought until the RMIT cluster became news.

How comprehensive and objective is the new IEEE RF exposure standard (C95.1-2005)? Not at all, says Vladimir Binhi of the General Physics Institute of the Russian Academy of Sciences in Moscow and the author of Magnetobiology. In a recent short comment, Binhi claims that the IEEE standard is biased, arguing that it dismisses non-thermal biological effects and ignores a large body of work documenting their existence. For its part, the IEEE committee, chaired by C.K. Chou of Motorola and John D'Andrea of the U.S. Navy (at Brooks Air Force Base), maintains that, "All relevant reported biological effects at either low '("non-thermal') or high ('thermal') levels were evaluated."

The brain tumor cluster at Australia's RMIT University is Topic A for EMF watchers around the world. It all began on Thursday when Australian TV news reported that the university had launched an investigation into seven cases of brain tumors among staff members in a 17-storey building on its Melbourne campus. Five of those who developed tumors worked on the top floor of the building (two others were on the 11th and 14th floors), and six of the seven had been there for more than a decade, according to the Australian, a national newspaper. Five of the cases were uncovered in the last month, while two others were reported in 1999 and 2001, Melbourne's The Age reported.

Another WHO RF Review Challenged

August 21, 2024
Last updated December 13, 2024

A third RF systematic review commissioned by the World Health Organization’s EMF Project is under fire. This one is on RF–induced oxidative stress.

Last month, two other WHO reviews —on pregnancy outcomes and on tinnitus— were both called into question as critics called for them to be retracted.

A team of 14 from six countries, led by Felix Meyer of the German Office for Radiation Protection (BfS), identified 11,599 studies on oxidative stress in the frequency range 800-2450 MHz. They then eliminated 11,543 of them as not meeting their criteria for inclusion.

Italy’s 6 V/m RF Limit at Risk

March 14, 2024

The International Commission on the Biological Effects of Electromagnetic Fields (ICBE-EMF) has written to Italian government officials to support the country’s strict 6 V/m RF exposure limit.

The letter, dated March 13, expresses “great concern” that the standard might be weakened. It is signed by Ronald Melnick, the chair of ICBE-EMF, and by Elizabeth Kelley, its managing director.

“NTP Lite”: Update from Japan

March 12, 2024

The Japanese group running a partial repeat of the NTP RF cancer study has not observed genotoxic effects among male rats exposed to 900 MHz CDMA radiation at 4 W/Kg, according to a paper to be presented tomorrow at the annual meeting of the Society of Toxicology in Salt Lake City, UT (SOT2024).

The analysis of the cancer data is ongoing and will not be reported.

Schwannoma Puzzle

Last updated September 16, 2023

Three medical doctors have published a case report of a 40-year-old Italian man who developed a tumor in his thigh, near where he “habitually” kept his smartphone in a trouser pocket.

The case was published at the end of August in Radiology Case Reports, a peer-reviewed, open access journal.

The tumor, a painless mass, gradually expanded in the man’s left thigh over a period of six months, they wrote.

Korean NTP Lite: Progress Report

June 16, 2023
Last updated June 17, 2023

A Korean RF genotoxicology study —part of a joint project with Japan— has been delayed due to the unexpected death of four of the RF–exposed rats early in the accompanying two-year cancer experiment, according to Young Hwan Ahn of Ajou University medical school.

Ahn presented a progress report on the Korean arm of the project in Geneva last week at a meeting of the WHO EMF Project’s International Advisory Committee. Microwave News has obtained a copy of Ahn’s PowerPoint presentation.
