Abstract

The mutagenic effect of SHF microwave radiation was studied in male mice using three test: frequency of dominant lethal mutations; frequency of abnormal sperm heads and frequency of chromosome aberrations in cells of bone marrow. The results of acute (60 and 800 mW/cm2 for 12 min, and 21 s., respectively) and fractionated (800 mW/cm2 for 21 s. X 10 days exposures of male mice did not induce any mutagenic effect.
