What is radiation in simple terms?

Radiation is energy that comes from a source and travels through space. It can be in the form of waves or particles.

Name two types of radiation.

Two types of radiation are electromagnetic radiation (like light, x-rays) and particle radiation (like alpha, beta particles).

What is the difference between ionizing and non-ionizing radiation?

Ionizing radiation can remove tightly bound electrons from atoms, creating ions. Non-ionizing radiation does not carry enough energy to ionize atoms.

What is an example of a natural source of radiation?

The sun is a natural source of radiation, providing both light and ultraviolet radiation.

What unit is used to measure radiation dose?

Radiation dose is typically measured in sieverts (Sv) or rems.
