WebThe effective dose includes a factor which adjusts for the biological effectiveness of different types of ionizing radiation, e.g. gamma-rays versus neutrons, and sensitivity of different tissues to ionizing radiation. One sievert of ionizing radiation has a biological effect equal to exposure of the whole body to 1 gray of gamma- or X-rays. WebDeterministic means there is a threshold of radiation dose below which the effect does not occur, however, once the threshold dose is passed the severity of the effect increases very rapidly. For example, skin erythema, ulceration, hair loss, sterility and cataracts are all examples of deterministic effects.
