What appliances have radiation and what type of radiation they have?

Answer 1

First off, Radiation is the spontaneous emission of particles or energy from a source, and depending upon where they originated from (the nucleus of an atom, or from an electron for instance) will determine their energy, and also their ability to penetrate matter.

Most common household appliances run from electricity and produce heat for cooking, or run a motor of some type to perform an action (like a blender, refrigerator pump, ect). The only appliance that emits radiation of any concern, would be your microwave. It has a microwave emitter built inside that when turned on, supplies just enough of a energetic wave to vibrate the molecules in your food, and this vibration causes them to heat up - thus warming your food up for you.

This appliance has been under alot of debate as to weather or not it will cause harsh affects if you stand next to it while it is running. The screens on the front of the microwave are sufficient enough to block the microwaves from exiting the inside, so you need not be worried. The microwave will only cause damage to your skin and tissue if you had your hand inside while it was turned on.
