Rather than falling at the high-energy end of the electromagnetic radiation band (where you’ll find X-rays, for example), microwaves are found on the low-energy radio frequency band (in the same neighborhood as radio signals). And the radiation is almost entirely confined to the oven. Federal standards require microwave ovens to have two independent interlocking systems that halt microwave production the moment the door latch is released or the door is opened, and a monitoring system that turns off the oven in case one or both of the interlocking systems fail. There are also federal standards for how much radiation leakage is acceptable, and the limits are far below the exposure level that’s considered a health risk.
