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).
