Microwaves emit microwave radiation, which is a form of non-ionizing radiation. Non-ionizing types of radiation are not very harmful to people in small doses, and they do not cause radiation sickness or cell damage like ionizing forms of radiation.Physicists consider microwaves, and the other non-ionizing forms of radiation, to be low energy electromagnetic radiation.he microwave oven has certainly been the most controversial of all kitchen-related inventions. Much of the concern surrounding the safety of microwaves regards the amount of radiation given off by one.
