This is a little fear mongering. Microwave is not ionizing. Therefore microwave does not cause radiation damage to tissues as ultraviolet, X-Ray, or high energy particle radiations would. Sufficiently intense microwave will cause heat burn damage to tissues by a different way, but with similar results, as holding your hand close to a infrared heat lamp, but that does not cause leukemia or hair loss.
Not when the intensity of the radiation is high. If what you said is true then why do they put radiation warnings on aircraft radomes?
