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.
The maximum permissible exposure for a person under 18 working with radiation is one-tenth the adult limit or not to exceed 500 millirems per year above the 300+ millirems of natural sources, plus medical radiation.5,000 millirems per year level was the federal occupational limit during World War II and until about 1950 for radiation workers and soldiers exposed to radiation. The occupational limit became 15,000 millirems per year around 1950. In 1957, the occupational limit was lowered to a maximum of 5,000 millirems per year.
