Whats the difference between radiation exposure and contamination?
A person exposed to radiation is not necessarily contaminated with radioactive material. You’re exposed to radiation every time you have an X-ray, but to be contaminated, the radioactive material must be on or inside the body. A contaminated person is exposed to radiation released by the radioactive material on or inside the body. An uncontaminated person can be exposed by being too close to radioactive material or a contaminated person, place, or thing. Exposure to radiation before birth can increase the risk of developing cancer later in life.
