No, fans do not give off radiation. Fans simply move air around to create a cooling effect by increasing air circulation. They do not emit any harmful radiation.
All objects give off thermal radiation.
Yes, fire gives off radiation in the form of heat and light.
Microwaves emit electromagnetic radiation in the form of microwaves when they are turned on. This radiation is absorbed by food and causes water molecules in the food to vibrate, generating heat that cooks the food.
A 'ray' is a term for a radiation. All objects with temperatures above 0 degrees Kelvin give off radiation called, "Heat".
Yes, humans give off a very small amount of radiation due to the natural radioactive decay of elements within our bodies, such as potassium-40. This radiation is very low in level and not harmful to others.
All cell phones give off varying degrees of radiation.
Radiation
Yes, fire gives off radiation in the form of heat and light.
All objects give off thermal radiation.
Yes - infrared radiation. If you're asking about nuclear radiation, then no.
Yes, the Earth does give off radiation in the form of heat. This radiation is primarily in the form of thermal infrared radiation emitted by the Earth's surface in response to solar energy absorbed during the day.
Microwaves emit electromagnetic radiation in the form of microwaves when they are turned on. This radiation is absorbed by food and causes water molecules in the food to vibrate, generating heat that cooks the food.
you have to use a radiation machine

Electromagnetic radiation.
they are magnetic
There are many electronic devices in the world that do in fact give off radiation. These devices include computers and microwaves for example.
