2. Researchers conducted a large battery of laboratory
tests to assess the effects of exposure to mobile
phone RF on genetic material. These included tests
for several kinds of abnormalities, including
mutations, chromosomal aberrations, DNA strand
breaks, and structural changes in the genetic
material of blood cells called lymphocytes. None of
the tests showed any effect of the RF except for the
micronucleus assay, which detects structural effects
on the genetic material. The cells in this assay
showed changes after exposure to simulated cell
phone radiation, but only after 24 hours of
exposure. It is possible that exposing the test cells
to radiation for this long resulted in heating. Since
this assay is known to be sensitive to heating, heat
alone could have caused the abnormalities to occur.
The data already in the literature on the response of
the micronucleus assay to RF are conflicting. Thus,
follow-up research is necessary.
FDA is currently working with government, industry, and
academic groups to ensure the proper follow-up to these
industry-funded research findings. Collaboration with the
Cellular Telecommunications Industry Association (CTIA) in
particular is expected to lead to FDA providing research
recommendations and scientific oversight of new CTIA-
funded research based on such recommendations.
Two other studies of interest have been reported recently in
the literature:
