What are the Sources of Ionizing Radiation?

What are the Sources of Ionizing Radiation?

Radiation can be natural or man-made. It is all around us.

Natural radiation may come from the outer space or from naturally occurring radioactive materials in air, food and water and on the earth crust.

Man-made radiation may come from medical X-rays, fallout from nuclear weapon tests and operation of nuclear power plants. Some consumer products, such as TV and luminous watches, contain man-made radioactive materials too.
