A Report on Non-Ionizing Radiation

The Karolinska group’s paper showing no increased risk of brain tumors among those who used a cell phone for ten or more years appears in the March 15 issue of the American Journal of Epidemiology. We first reported this result in December based on a brief announcement from Stockholm, but the published paper offers many more details.

One interesting item is the finding of a somewhat elevated risk of developing a glioma (a 60-80% increase) on the same side of the head as the phone was used. But, the Karolinska researchers also saw a lower than expected glioma risk on the opposite side of the head.

One of the lessons to be learned from the aftermath of the second Stewart report, released by the UK NRPB last week (see below), is that interpreting the mobile phone health data is much like reading Rorschach inkblots. What you see depends a lot on your mind-set.

Robert Matthews, the Daily Telegraph’s science correspondent, thinks that Sir William made “a bad call.” After noting that there were concerns at the NRPB press conference over last October’s Karolinska study, that showed a doubling of the risk of acoustic neuromas among those who had used a cell phone for more than ten years, Matthews went on to write: “What was not made clear, however, is that the tumor is benign, non-fatal and astonishingly rare: just one person is affected per 100,000 per year.”

Epidemiologists at the Karolinska Institute in Stockholm have found no association between the use of cell phones and the risk of brain tumors.

“No increased risk was found for glioma or meningioma related to mobile phone use,” reports Stefan Lönn and coworkers at the Institute of Environmental Medicine. Lönn completed the study as part of his doctoral dissertation under the direction of Maria Feychting. This work is part of the Interphone study being coordinated by the International Agency for Research on Cancer (IARC) in Lyon, France.

Mobile phones may present a cancer risk after all. Epidemiologists at the Karolinska Institute in Stockholm have found that the phones can increase the incidence of acoustic neuromas, benign tumors of the auditory nerve. The nerve is exposed to radiation during the normal use of a cell phone.

Those who used mobile phones for at least ten years, had close to twice the risk of developing acoustic neuromas, according to a team led by Dr. Maria Feychting and Prof. Anders Ahlbom of the Karolinska’s Institute of Environmental Medicine. Ahlbom is the deputy director of institute.

The irony is astonishing. On the very day that a committee of the National Council on Radiation Protection and Measurements (NCRP) completed its 800-page draft report asking regulatory agencies to pay “serious attention” to EMFs, public television station WGBH aired a one-hour show across the country comparing EMFs to cold fusion. While the NCRP committee called for “a national commitment to further research,” the June 13 Frontline, “Currents of Fear,” asked whether it was time to close down the research effort.
