“In conclusion, despite the improved quantitative exposure assessment used in this study, the results do not support a positive association between occupational exposure to high-frequency EMF and either glioma or meningioma risk. However, given our limited statistical power, due to the small number of exposed participants, and despite our results’ lack of significance our findings foster the need for further research focusing on RF magnetic fields and tumor promotion, as well as possible interactions with other frequencies and with chemicals.” (see press release.)

“The results indicate that the current densities induced in the brain during DECT calls are likely to be an order of magnitude lower than those generated during GSM calls but over twice that during UMTS calls.” See also the group’s earlier paper.

The latest analysis from Interphone. The same tensions continue with no clear consensus.

INTEROCC and INTERPHONE have a lot in common —more than their first five letters. So much in common that it’s a bit freaky. Or, maybe it just shows, once again, how small, insulated and polarized the EMF community is.

The most obvious parallels are that Elisabeth Cardis is the principal investigator of both the...

Power-frequency magnetic fields can promote brain tumors, according to the largest epidemiological study of its kind ever undertaken. The study promises to breathe new life into the idea that extremely low frequency (ELF) EMFs are more likely to be cancer promoters than causes of cancer. This hypothesis gained support a generation ago but has lost currency in recent years.

The new results, published online earlier this month by the journal Cancer Epidemiology, Biomarkers & Prevention, come from INTEROCC, an international project with seven participating countries designed to investigate occupational health risks from chemicals and EMFs. The project is directed by Elisabeth Cardis at CREAL in Barcelona with $1.5 million from the U.S. National Institutes of Health (though none of the tumor cases are from the U.S.).

The INTEROCC team found that those who were exposed to elevated EMF exposures at work during the five years prior to diagnosis had significantly higher rates of glioma compared to those who were least exposed during that time on the job. The greater the exposure, the greater the tumor risk.

“[M]easurements suggest that mobile phones could make a substantial contribution to ELF exposure [at 217 Hz and associated harmonics] in the general population.” From the Mobi-Kids study team.

The battle over Interphone continues. This time it's in full public view as key players publish papers detailing where they stand on cell phone tumor risks. There haven't been any big surprises since their opinions have long been known. Yet, the diametrically opposing views have led to conflicting stories in the media as each new study is released.

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.
