Acute low-intensity microwave exposure increases DNA single-strand breaks in rat brain cells
- Univ. of Washington, Seattle, WA (United States)
Levels of DNA single-strand break were assayed in brain cells from rats acutely exposed to low-intensity 2,450 MHz microwaves using an alkaline microgel electrophoresis method. Immediately after 2 h of exposure to pulsed (2 {mu}s width, 500 pulses/s) microwaves, no significant effect was observed, whereas a dose rate-dependent [0.6 and 1.2 W/kg whole body specific absorption rate (SAR)] increase in DNA single-strand breaks was found in brain cells of rats at 4 h postexposure. Furthermore, in rats exposed for 2 h to continuous-wave 2,450 MHz microwaves (SAR 1.2 W/kg), increases in brain cell DNA single-strand breaks were observed immediately as well as at 4 h postexposure.
