Female CD 1 mice were exposed from the thirty‐fifth day of age for the remainder of their lives to 2.45 GHz, CW‐microwave radiation at a power density of 3 or 10 m W/cm 2 (SAR = 2.0 or 6.8 W/kg). Exposures took place 1 h/day, 5 day/week in an anechoic chamber at an ambient temperature of 22 °C and a relative humidity of 50%. There were 25 animals in each exposure group, and an equal number of controls were concurrently sham exposed. The average life span of animals exposed at 10 mW/cm 2 was significantly shorter than that of sham‐exposed controls (572 days vs. 706 days; P = .049; truncation >20%). In contrast, the average lifespan of the animals exposed at 3 mW/cm 2 was slightly, but not significantly, longer (738 days) than that of controls (706 days). © 1994 Wiley‐Liss, Inc.
