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.
Ionizing radiation can injure the developing embryo due to cell death or chromosome injury. There is no proof that human congenital malformations have been caused by diagnostic levels of radiation. The most critical exposure period is 8â15 wk after fertilization [5,6]. Before implantation, the mammalian embryo is insensitive to the teratogenic and growth-retarding effects of radiation and sensitive to the lethal effects [7â9].
