Description

The mutagenic activity of microwave radiation at 2450 MHz and heat to levels comparable to that produced by microwave radiation treatment were investigated using histidine auxotrophs-hisTA98, hisTA100, hisTA1535, hisTA1537, and hisTA1538 - of Salmonella typhimurium LT2 developed by Dr. B. N. Ames. The conventionally used microwave oven caused a significant increase in the number of revertant colonies in all the S. typhimurium strains tested. Heat alone, although mutagenic, produced fewer revertant colonies than microwave radiation. We concluded that microwave radiation of 2450 MHz is a potent mutagen and therefore a potential carcinogenic agent for animals.
