Radiation: A Fact Of Life
Radiation is a form of energy like sunshine or light. It is all around us and we receive very small amounts of radiation, known as background radiation, each day. It is in the air we breathe, the food we eat, our homes, and even in our bodies.
In addition to background radiation, there is artificial radiation from such things as medical and dental X-rays and nuclear medicine treatments.
Very small amounts of radiation come from the generation of nuclear power.
