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.

Second phase of CRADA 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.
