• 10 CFR 20, Standards for Protection Against Radiation. The NRC requires licensees to maintain exposure to the fetus of an occupationally exposed individual to 500 mrem (5 mSv) or less during the gestation period.

• 1990 Recommendations of the International Commission on Radiological Protection. Report 60. Recommends a limit of radiation exposure to a member of the general public as 100 mrem/y (1 mSv/y) and the limit for the fetus of an occupationally exposed individual to 200 mrem (2 mSv) during the gestation period.

• Limitation of Exposure to Ionizing Radiation. Report 116. Recommends a limit of radiation exposure to a member of the general public as 100 mrem/y (1 mSv/y) and the limit for the fetus of an occupationally exposed individual to 50 mrem (0.5 mSv) per month during the gestation period.

• Radiation Protection. Suggests state regulations for radiation protection. In Subpart D, the suggested regulations state that the limit on exposure to the fetus of an occupationally exposed worker be kept below 500 mrem (5 mSv) during the gestation period.
