We haven't posted many new items recently because we've been too busy fixing up the new Web site. In the process, we've been rereading many of our old stories. Last night, we came across an item from five years ago under the title "Cell Specific Responses to RF." It highlighted some new research from Finland, which found that cell phone radiation affected the activity of ODC, a biologically important enzyme, in ...

The incidence of acoustic neuroma is not increasing in the Nordic countries, according to researchers from Denmark, Finland, Norway and Sweden. The team —made up of members of Interphone that don't believe that cell phones lead to tumors looked at cancer registry records from 1987 to 2007.

Their paper appears in the September 27 issue of the ...

Getting a handle on EMF and RF effects is a frustrating business. A new paper in the March 9 issue of Mutation Research from Finland's University of Kuopio tells the story. The Kuopio research group found that mobile phone radiation, at 5W/Kg, can amplify the DNA damage caused by a chemical mutagen. This is far from the first time an RF-induced genotoxic effect has been reported (see our September 3, 2008 post).

Every now and then a new paper comes along that gives hope that one day we'll make sense of the conflicting results that have become the hallmark of EMF research. A team of Finnish researchers from the University of Kuopio has published such a paper. It's in the June issue of the International Journal of Radiation Biology.

Anne Höytö, Jukka Juutilainen and Jonne Naarala have shown that the type of cells used in in vitro studies can determine whether they will respond to RF radiation. They ran the same experiment with primary cells —those taken directly from an organism— and with secondary cells —those that have been grown in a petri dish. They exposed both types of cells to two different RF signals, CW and modulated (GSM), at various intensities (SAR =1.5, 2.5 or 6 W/Kg) for various amounts of time (2, 8 or 24 hr), and then measured the activity of ODC (ornithine decarboxylase), an enzyme related to cellular growth and differentiation.

An international team of researchers has found new evidence that long-term use of a mobile phone may lead to the development of a brain tumor on the side of the head the phone is used. In a study which will appear in an upcoming issue of the International Journal of Cancer, epidemiologists from five European countries report a nearly 40% increase in gliomas, a type of brain tumor, among those who had used a cell phone for ten or more years. The increase is statistically significant. In addition, there was a trend showing that the brain tumor risk increased with years of use. The new paper is posted on the journal's Web site.

Dariusz Leszczynski, of the Radiation and Nuclear Safety Authority ( STUK) in Helsinki, has been appointed Guangbiao Professor at China's Zhejiang University Medical School. Over the next three years, Leszczynski will spend one month each year at the university's Bioelectromagnetics Lab, where he will collaborate with Zhengping Xu. Together, they will focus on the effects of cell phone radiation on human proteins. At the same time, Leszczynski will continue to serve as the head of STUK's radiation biology lab, where he has been a leader in applying proteomic and transcriptomic techniques to the study of RF biological effects.

The radiation protection agencies in Denmark, Finland, Iceland, Norway and Sweden have issued a joint statement agreeing that “[T]here is no scientific evidence for any adverse health effects from mobile telecommunications systems, neither from base stations nor from headsets below the [ICNIRP exposure limits].” Even so, the agencies go on to endorse a policy of “prudent avoidance,” stating that, “The existing gaps and the prevailing scientific uncertainty justify a certain precautionary attitude regarding the use of handsets for mobile telephony. ”
