Another 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.

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".
