study fails to show DNA damage with RFR exposure
In last month's
"What's New" we discussed two papers that failed to confirm
earlier reports of DNA
damage following exposure to radiofrequency radiation (RFR). Now
another paper has been published from the same group of authors
that has failed to confirm the findings of an earlier report of
DNA damage. The authors exposed cells to RF fields, and studied
four types of frequency/modulation used by wireless communications.
They also used a radial transmission line exposure system. None
of the exposures produced alterations in the amount of DNA damage.

impact of EM radiation on blood cells
A Swedish paper
has generated interest in the lay press by suggesting a mechanism
by which electromagnetic radiation from cell phones could damage
cells. The paper is a theoretical one. It uses a series of mathematical
calculations that predict that the radiation could cause red blood
cells to align in one direction, thus increasing the forces between
the cells by about ten orders of magnitude. The author suggests
that this might cause tissue damage, but emphasizes that there are
weaknesses in the calculations, and they should "not be considered
as a proof that cellular phones are harmful".
