Gamma rays are used to steralise equipment.
Gammas are also used in "radioactive meals", so they can see where the food you eat is going inside your body.
CAT scans also use gammas.
Also, if you want a stupid answer: light bulbs emit visible light, and heaters emit infra-red - both forms of electromagnetic fields.

X-rays, of course. MRI uses powerful radio frequency radiation. Infrared lasers are used in laser eye surgery. Visible light is used to inspect your tonsils. Ultraviolet light is sometimes used to sterilized things. Gamma rays from radioactive isotopes are used in some cancer treatments. Microwaves are used in the hospital cafeteria :- ) It seems like docs use just about the whole spectrum.
