Sprague-Dawley rats were irradiated in Plexiglas tubes with a continuous wave (CW) or pulsed wave (PW) radiofrequency (RF) for 6 hr/day, 5 days/wk from 2 up to 24 mo of age. The SAR was 1.0 W/kg averaged over the brain. Fifteen groups of 60 rats (900) were formed from offspring of females injected IV with 0 (groups 1, 2, 9, 10, 13), 2.5 (groups 5, 6, 7, 8, 11, 12, 14), or 10.0 mg/kg (groups 3, 4, 15) ethylnitrosourea (ENU) to induce brain tumors (BT). Groups 1, 3, 5, 7, received the PW RF, groups 9 and 11 the CW RF, groups 2, 4, 6, 8, 10, 12 were sham irradiated and groups 13-15 were cage controls. All rats were necropsied and major tissues studied histopathologically. There was no statistically significant evidence that the PRF or CW RF affected survival or initiated or promoted BT or any other neoplasms. The 10.0 mg/kg ENU PW RF (group 3) did, however, have more fatal BTs, and more multiple BTs (neither was statistically significant) with shorter latencies (p=0.045) than shams (group 4). Studies designed to confirm or disclaim any possible PW RF effects on BT latency or other promoting effects of the PW RF are underway. (0 Refs). [Copyright 2000, Information Ventures, Inc.]
The Information Ventures, Inc., EMF Database is a unique and comprehensive computerized database of analytical abstracts of research literature on biological effects of nonionizing electromagnetic radiation. The database supports researchers, engineers, policy makers, and other interested parties by analyzing and compiling the world's scientific and technical literature on EMF bioeffects in a comprehensive convenient resource. The EMF Database is distributed on CD-ROM.
Each entry consists of a complete bibliographic citation, detailed abstract, and other relevant data such as author affiliation, and funding source. The EMF Database contains over 27,000 entries covering the international literature published since 1975. To keep the database timely, new information is added in quarterly updates.
