Radiation Units,r types of radiation, such as heat, is to raise the temperature of the absorbing medium. If this medium is the human body, or part of it, the rise in temperature is sensed and, if it becomes excessive, avoiding action can be taken, by sheltering under a sunshade (shielding), for example, or by moving further away from a fire (distance).

Such substances are said to be . and the transformation process is known as .. Radioactive decay is usually accompanied by the emission of charged particles and gamma rays.

On the other hand, when radioactive material is not contained in any way it constitutes a potential .. Radioactive material which is inadvertently released is known as ..
