Final answer:
The NCRP gestational dose-equivalent limit for an embryo/fetus of a pregnant radiographer is 0.5 rem (5 mSv) for the entire pregnancy.
Step-by-step explanation:
The National Council on Radiation Protection and Measurements (NCRP) specifies that the gestational dose-equivalent limit for the embryo/fetus of a pregnant radiographer should not exceed 0.5 rem (5 mSv) for the entire gestation period. This precaution is intended to protect the developing fetus from potential adverse effects of radiation exposure. Understanding radiation doses and their effects is crucial for anyone working with ionizing radiation, particularly in medical settings where radiographers may be exposed during their duties. The dose limit reflects the importance of balancing the benefits of radiation in medical diagnostics and treatment against the potential risks, especially during sensitive developmental stages like pregnancy.
