摘要
Two kinds of cells (HCE-T and SRA) derived from human eye were exposed to a millimeter-wave for 24 hours. The micronucleus (MN) frequency of cells treated with bleomycin for 1 hour was high enough as a positive control. However there is no statistically significant increase in the MN frequencies of the cells exposed to 60 GHz millimeter-wave at 1 mW/cm(2) compared with sham-exposed controls and incubator controls. The comet assay to detect DNA strand breaks also showed that the exposure of the millimeter-wave for 24 hours did not have statistically significance. These results indicate that the exposure to the millimeter-wave would be considered to have no effect on the genotoxicity to the human eye cells.
