Hazards and uses of radiation



In this video, we’ll look at the effects of ionising radiation on cells within the body and how radiation dose measurements allow us to determine the relative risk posed by a given exposure to radiation.  We’ll then go on to look at the technique or carbon dating, before looking in detail at the uses of radioactive tracers in medicine and the use of radioactive substances for the treatment of certain medical conditions.
