The only way to check for microwave leaks is to check it with an radiofrequency radiation (RFR) probe, which are very expensive and require technical training to operate.
Unless the microwave, and especially the door, have noticeable damage you can be very confident that exposure is very negligible and that no adverse health effects will come of it. As an added precaution, it is smart to stay several feet away from the microwave while it is cooking, since radiation levels drop sharply with increased distance.
You can buy a leakage detector for $40. Please note that these detectors are not certified by any government regulatory agency and therefore the manufacturer can make any claims they want - similar to the claims seen on "supplements" sold at the drug store.
Leakage of microwave radiation past the door seal in a microwave oven.
Leakage of possibly harmful microwave radiation from an operating microwave oven due to damaged door seals etc.
microwave radiation is radiation that comes from microwaves
Microwave is lower frequency.
A new microwave having a label stating that is meets FDA standards for minimal radiation leakage is the safe choice and will leak the least amount of microwave radiation. You can also protect yourself by not leaning against a microwave while it's operating, and not using a microwave with a door that does not close firmly.
microwave ovens and microwave communications.
All ultraviolet radiation has shorter wavelengths than any microwave.
A microwave heats food by radiation No, a microware works with microwaves, not radiation.
Yes, microwave ovens use electromagnetic radiation.
A microwave oven generates microwave radiation, which is a form of non-ionizing electromagnetic radiation. Links can be found below for more information.
