Radiation dose to the embryo/fetus: Draft Regulatory Guide DG-8011

Technical Report · Sat Feb 01 04:00:00 EST 1992

OSTI ID:5530730

Section 20.1208 of 10 CFR Part 20, Standards for Protection Against Radiation,'' requires that each licensee ensure that the dose to an embryo/fetus during the entire pregnancy, from occupational exposure of a declared pregnant woman, does not exceed 0.5 rem (5 mSv). Paragraph 20.1208(b) requires the licensee to make efforts to avoid substantial variation above a uniform monthly exposure rate to a declared pregnant woman that would satisfy the 0.5 rem limit. The dose to the embryo/fetus is to be the sum of (1) the deep-dose equivalent to the declared pregnant woman (10 CFR 10.1208(c)(1)) and (2) the dose to the embryo/fetus from radionuclides in the embryo/fetus and radionuclides in the declared pregnant woman (10 CFR 20.1208(c)(2)). This guide is being developed to provide guidance on calculating the radiation dose to the embryo/fetus.
