In the Collins WXR 2100 operators handbook (installed on many Airbus and Boeing aircraft) it says
"The WXR-2100 power density is half or less than that of the microwave oven standard." and "Some sources suggest that any radiation exposure can be harmful, especially long term. Each airline must make their own decision on this, as exposure to radiation is occasionally cited by an employee as a cause of some physical injury."
So my recommendation it to stay away from your home microwave. My aunt was hired to help a woman die comfortably and the doctor said this woman didn't have much longer to live. She had some condition where her skin and organs started to become as hard as a rock from an unknown cause. My aunt removed the microwave from the woman's house and the woman is now almost fully recovered. Apparently the microwave and food cooked in it can really screw you up. My mom just removed her microwave but I still have one.
