Radiation Contamination Versus Exposure
External contamination occurs when radioactive material comes into contact with a person’s skin, hair, or clothing.
Another word for radiation exposure is irradiation.
Radioactive materials give off a form of energy that travels in waves or particles.
When a person is exposed to certain types of radiation, the energy may penetrate the body.
A person exposed to radiation is not necessarily contaminated with radioactive material.
For a person to be contaminated, radioactive material must be on or inside of his or her body.
