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.

Exposure

microwave · acute (12 min at 60 mW/cm2; 21 s at 800 mW/cm2) and fractionated (21 s at 800 mW/cm2 for 10 days)

Evidence strength

Low

Confidence: 74% · Peer-reviewed: yes

Main findings

In male mice, acute and fractionated SHF microwave exposures at the stated power densities and durations did not induce mutagenic effects as assessed by dominant lethal mutations, abnormal sperm heads, or bone marrow chromosome aberrations.

Outcomes measured

dominant lethal mutations
abnormal sperm head frequency
chromosome aberrations in bone marrow cells

Limitations

Frequency (SHF/UHF) not specified numerically in the abstract
Sample size not reported in the abstract
Dosimetry beyond incident power density (e.g., SAR, temperature) not reported in the abstract
