ID Number		834
Study Type		In Vitro
Model		836.5 MHz, 1.765 GHz (CDMA) exposure to various cells in culture and analysis of growth
Details		Jurkat (human T-cells), WI-38 (human fibroblasts), DO11.10 (mouse T cells), and C3H 10T1/2 (mouse fibroblasts) were exposed to 836.5 MHz (CDMA) at up to 36.5 W/kg and 1.765 GHz (CDMA) at up to 38.2 W/kg for up to 72 hours. At the highest level of exposure, growth rate was reduced in human and mouse immune cells during exposure, but recovered after exposure was complete. No effect on growth rate was observed on human or mouse fibroblast cells. No effect on transformation or chromosome aberrations was reported. In mouse fibroblast cells, actin polymerization was increased, seemingly due to a stress response. In other studies, human T-lymphocytes were exposed to 1.765 GHz at 1.5 and 75 W/kg. At high (thermal) levels of exposure, cell growth decreased with a slight decrease in DNA synthesis, actin polymerization increased, and no chromosome abnormalities were detected. At 1.5 W/Kg, no effects were observed. The authors conclude no short-term effects of RF exposure beyond obvious thermal effects.

Comments		No heat control was reported, and initial reports of this study described a maximal SAR of 75 W/kg. It is not clear if any careful monitoring of the exact temperature was performed during the high SAR exposures.
