What is the regulatory provision for occupational exposure of a declared pregnant woman PER MONTH?

The regulatory provision for occupational exposure of a declared pregnant woman is set at 0.05 REM (or 50 mrem) per month. This limit is established to protect the developing fetus from the potential harmful effects of ionizing radiation during pregnancy. The value is derived from guidelines that take into account the sensitivity of fetal tissues and aim to minimize radiation exposure while still allowing the mother to perform her occupational duties, as long as proper safety measures are in place.

This monthly limit is part of broader regulatory frameworks that govern radiation safety in the workplace, ensuring that both employees and their potential offspring are kept safe from excessive levels of radiation exposure. In comparison, the other options presented reflect values that either exceed or do not align with the established regulatory limits for pregnant workers, which is why they are not correct.
