Effective dose

The Effective Dose is obtained by taking the Equivalent Dose (Dose Equivalent) and multiplying by a Tissue Weighting Factor which relates to the organs / tissues under consideration. Effective Dose can therefore also be considered a doubly weighted Absorbed Dose since it takes into account the type of radiation (radiation weighting factor) and the target organ / tissue. The quantity can be used to express Detriment to the whole body as a summation of several different doses of radiation with varying radiation weighting factors (radiation type) and targets.

Radiation is one of the important factors in evolution. It causes mutation, and some level of mutation is actually good for evolution
