Polonium-210 primarily emits alpha radiation, which consists of two protons and two neutrons. This type of radiation has a low penetrating power and is highly ionizing, making it hazardous if ingested or inhaled.
It's a semantic thing - by definition, if something gives out radiation, then it is radioactive. If an element gives off radiation, then it is a 'radioactive' element. If it does not give out radiation, then it is not 'radioactive'.
Radioactive elements.
Let's try to give off pleasant vibrations.
A body that can give off electromagnetic radiation (light) such as the Sun, a lightbulb, etc.
They give off carbon dioxide.
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.
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.

A 'ray' is a term for a radiation. All objects with temperatures above 0 degrees Kelvin give off radiation called, "Heat".
