Answer 1

Radiation:

• Radiation is the emission or transmission of energy in the form of waves or particles via space or a material medium in physics.
• Radiation is produced anytime energy is transferred.
• To release radiation, a material does not have to be radioactive.
• Not all element isotopes release radiation.
• Light, heat, and alpha particles are all examples of radiation.

Examples of Radiations:

1. Sunlight ultraviolet light heat from a stove burner visible light from a candle
2. X-rays taken using an x-ray machine
3. The radioactive decay of uranium produces alpha particles.
4. Stereo's sound waves
5. Microwaves produced by a microwave oven
6. Your cell phone emits electromagnetic radiation.
7. A black lamp emits ultraviolet light.
8. Beta particle radiation from a strontium-90 sample
9. A supernova's gamma radiation
10. Microwave radiation emitted by your wifi router
11. Radio frequencies
