What is the occupational radiation dose limit for an embryo/fetus of a declared pregnancy?

The occupational radiation dose limit for an embryo/fetus of a declared pregnancy is established to protect the developing fetus from potential harm due to exposure to radiation. According to guidelines set by various regulatory agencies, the appropriate limit is 0.5 rem (or 500 millirem) per gestation period. This limit is designed to minimize the risk of adverse effects, including potential developmental issues, while allowing for necessary occupational exposures in a controlled manner.

Setting this limit at 0.5 rem reflects a balance between ensuring safety for the fetus and allowing women who are pregnant to continue to work in environments where radiation may be present, provided that appropriate safety measures are followed. It emphasizes the importance of monitoring and managing radiation exposure for pregnant workers to maintain both their safety and the safety of the developing child.
