Hi Doc.First of all, congratulations for this website.
My question is the following: Can an exposure to common microwave-oven rays cause hair-loss? If so, to what extent? Thank you for your help
Common microwave oven rays should not cause hair loss, but I am not a physicist. I would like to believe common microwave ovens are safe as long as you use it as it is intended according to manufacturer’s instruction. According to the United States Department of Labor Occupational Safety and Health Administration (OSHA) microwave (MW) radiation are electromagnetic radiation in the frequency ranges 300 MHz – 300 gigahertz (GHz), respectively.
Most of what I find on microwave radiation is from commercial applications such as cellular phones and radar (not microwave ovens). Some sites have quoted a 1998 book, “The Body Electric“, that mentions a Russian study concluding that hair loss occurs from microwave ovens, but I can’t vouch for this. I would also check out the U.S. FDA site on microwave oven radiation.
