Once the total effective dose to the embryo/fetus of the declared pregnant woman exceeds 400 mRem, she will be restricted from any further work involving occupational radiation exposure for the remainder of the pregnancy.
Thus, at high doses of radiation, the threshold for damage in several tissues is. exceeded, and severe biological effects are pre-. dictably observed. When humans are exposed to relatively high. doses of radiation (greater than 50 rads1; see the. 1 1 rad = 0.01 joule/kg = 0.01 gray. discussion of units used to describe radioactivity. and radiation dose in box 3-1) to the whole body, deterministic effects of radiation will occur. within hours, days, or weeks.
