Learn what radiation is, how it travels, and how it affects matter. Find out about natural and artificial sources of radiation, and how they contribute to your exposure.
Radiation is energy that travels in the form of waves or particles and is part of our everyday environment. People are exposed to radiation from cosmic rays, as well as to radioactive materials found in the soil, water, food, air and also inside the body.
