Abstract Female Sprague-Fawley (CD) rats were exposed to 2450-MHz (CW) microwave radiation
at incident power densities of 0 to 28 mW/cm² for 100 min
daily on the 6th through 15th day of gestation. The whole-body specific absorption rate at 28 mW/cm² is estimated to be 4.2 W/kg. These exposure conditions raised rats'
average colonic temperatures to 40.3ºC at the end of irradiation. There were
67 sham-irradiated and 70 microwave-irradiated females. When these groups were compared, no
significant differences were found in pregnancy rates; in the numbers of
live, dead, or total fetuses; in the incidences of
external, visceral or skeletal anomalies or variations; or in the body weight
of live fetuess. It is concluded that
these conditions do not have an effect on the gross structure of the fetal rat when applied repetitively during post-implantation
pregnancy. It is also strongly suspected that this lack of an effect may hold
true at any exposure level less than that which will kill a significant
number of the dams by hyperthermia (colonic temperature > |
