DNA Damage in Hippocampal Cells of Rats Induced by Exposure to 1800 MHz Electromagnetic Irradiation / 环境与健康杂志

ABSTRACT

Objective To study the DNA damage in hippocampal cells of rats induced by 1 800 MHz electromagnetic irradiation. Methods Wistar rats were randomly divided into four groups, 2 exposed groups and 2 controls. The experimental subjects were exposed to the 1 800 MHz (continuous wave, CW) electromagnetic fields for 21days (12 h/d), the power densities were 0.5 mW/cm2 and 1.0 mW/cm2, meanwhile, sham-control exposures were carried out, the DNA damage was examined by Comet assay. Results The tailed rate and the tail area of the hippocampal cells in 1.0 mW/cm2 group was higher or larger than those in the control and 0.5 mW/cm2 groups(P
