Final answer:
The NCRP recommends an occupational dose limit of 0.5 mSv per month for an embryo/fetus to protect it from the potential hazards of ionizing radiation in occupational settings.
Step-by-step explanation:
The National Council on Radiation Protection and Measurements (NCRP) Recommended occupational dose limit for an embryo/fetus is 0.5 mSv per month. To support radiation protection by providing independent scientific analysis, information, and recommendations that represent the consensus of leading scientists. This is to ensure the protection of the developing fetus, especially considering the sensitivity to ionizing radiation at this stage of development. It's important to note that this recommendation is typically part of a more comprehensive set of guidelines that aim to protect workers and their unborn children from potential radiation hazards in occupational settings.
