Effective dose is a dose quantity in the International Commission on Radiological Protection (ICRP) system of radiological protection. [1]It is the tissue-weighted sum of the equivalent doses in all specified tissues and organs of the human body and represents the stochastic health risk to the whole body, which is the probability of cancer induction and genetic effects, of low levels of ...
Radiation weighting factors that go from physical energy to biological effect must not be confused with tissue weighting factors. The tissue weighting factors are used to convert an equivalent dose to a given tissue in the body, to an effective dose, a number that provides an estimation of total danger to the whole organism, as a result of the ...
This is taken into account by the equivalent dose (H), which is defined as the mean dose to organ T by radiation type R (D T,R), multiplied by a weighting factor W R. This designed to take into account the biological effectiveness (RBE) of the radiation type, [ 8 ] For instance, for the same absorbed dose in Gy, alpha particles are 20 times as ...
The second weighting factor is the tissue factor W T, but it is used only if there has been non-uniform irradiation of a body. If the body has been subject to uniform irradiation, the effective dose equals the whole body equivalent dose, and only the radiation weighting factor W R is used. But if there is partial or non-uniform body irradiation ...
This refers specifically to the dose in a specific tissue or organ, in the similar way to external equivalent dose. Committed effective dose, is the sum of the products of the committed organ or tissue equivalent doses and the appropriate tissue weighting factors W T , where t is the integration time in years following the intake.
