Evaluation of potential genotoxocity of RF fields In Vivo, using the single cell gell (SCG) electrophoresis assay. Tice RR, Vasquez M, McDougal J, Chou CK, Hook GJ, McRee D Prsented at the WTR Seccond State of the Science Colloquium in Long Beach California 1999 Motorola-funded WTR project Contractors: Integrated Laboratory Systems, Research Triangle, North Carolina; and WTR. This research was a follow-up to the published 1995 findings of Drs Lai and Singh on RF-induced DNA damage, but used a signal common to wireless communications rather than the original 2450 MHz exposure. It involved parallel studies carried out by ILS and by Drs Lai and Singh at the University of Washington. Male Sprague Dawley rats were exposed for 2 hours to 837 MHz CW at 1, 2 & 4 W/kg and brain cells were isolated and analysed tor DNA breaks using the Singh comet assay method. No effects were reported by ILS. According to data reported at this meeting, Drs Lai and Singh initially observed an effect at the lowest of the three exposure levels used, but the effect could not be reproduced on subsequent investigation by the two researchers. |
Additional Web NotesThere are two sides to this story -- and note that only the ILS reported 'no effects'. Lai and Singh maintain that an attempt was made to trick them in various ways, and they complained bitterly because records of the exposures could not be produced when requested. You can believe either side in this on-going debate.This is research funded by the Cellular Telephone Industry Association's WTR (Wireless Technology Research) group under Dr George Carlo's direction. See Dr Carlo's letter to Motorola and the key CTIA executives after leaving WTR. It is interesting to see which WTR studies Motorola just ignored. |
