Replication of Repacholi study shows no tumour increase

In 1997 Repacholi and his colleagues reported that exposure of mice to radiofrequency (RF) radiation at 900 MHz for 18 months increased the incidence of lymphoma. These authors stated that there was a need to "replicate and extend" their study. The first study to do this has now been published. Utteridge and co-authors at the University of Adelaide used the same strain of mice as in Repacholi's - one that is particularly prone to develop lymphoma. They included refinements designed to overcome perceived shortcomings in the original study. Utteridge and colleagues found that long-term exposures of the mice to 898.4 MHz RF at SARs of 0.25, 1.0, 2.0 and 4.0 W/kg had no significant effects when compared to sham-irradiated animals. In other words, the findings of Repacholi and colleagues were not confirmed.

More on this study can be found in "Research - Toxicological Experiments - cancer studies".

Second phase of CRADA research

In "Research Programs " we discuss the Cooperative Research and Development Agreement (CRADA) between the U.S. Food and Drug Administration and the Cellular Telecommunications and Internet Association. Solicitations are now being made for research studies of Phase 2 of this agreement. These studies will evaluate the best epidemiological tools for measuring exposure to radiofrequency (RF) from wireless phones.
