✦ Synopsis

Average specific absorption rates (SARs) for live rats exposed in 2,450-MHz circularly polarized waveguides were estimated from the total system loss determined from measurements using five power meters, and a correction factor representing actual SAR/apparent SAR. The actual SAR was measured by twin-well calorimetry and the apparent SAR by power meters. Values were obtained for carcasses of various body masses for five orientations. The average SAR with free movement in the cages changed less than threefold as the rats grew from 200 to 700 g. The ratio of peak to average SAR in the body was less than 3. These results indicate relatively constant energy disposition in rats exposed in the circularly polarized waveguide.

Rats were exposed to 2,450-MHz pulsed microwave fields in a circularly polarized waveguide. The threshold incident energy density per pulse was about 1.5 to 3 pJlcm' over the range 1-10 ps. The corresponding whole-body averaged specific absorption of energy was 0.9 to 1.8 d l k g per pulse. The same

## Abstract Tests of mutagenesis and reproduction were conducted in male rats which were irradiated by 2,450‐MHz, continuous‐wave (CW) microwaves, 4 hr/day from day 6 of gestation to 90 days of age at 5 mW/cm^2^; or 5 hr/day for five days beginning on the 90th day of age at 10 mW/cm^2^; or 4 hr/day
