Gcse radioactive contamination
WebAlthough irradiation can cause harm, contamination has the potential to cause far more harm, due to the continuous exposure to radiation that it will produce. Contamination is particularly dangerous if a radioactive source gets into the human body. The internal organs will be irradiated as the source emits radiation as it moves through the body.
