Document Summary
In theory, we don"t see any harmful effects of microwave radiation. In such a low concentration, there is no evidence that it is harmful. But, microwave radiation, in general (no just from microwave oven, but in general from anywhere), can cause some health affects. It can heat our tissue in the same way it heats food. Coagulation of proteins (cooking our own body) and other things. What is especially sensitive to high heat are our lenses. This can cause cataracts (problem with eyes in areas where people live in very sunny places). Painful burn and temporary sterility (alter or kill sperm) can also occur by microwaves. Smoke detectors and alarms: in every smoke detector or alarm, there is a tiny amount of radioactive material. It"s so small, that an adult or child can ingest it. But, that radioactive material is needed to produce an electric current, and smoke breaks that current, and this is how the alarm is triggered.
