Final answer:
Immediate notification of the AFMOA/Bioenvironmental Engineering Division is required for a dose to the embryo/fetus of 500 mrem, due to the high sensitivity and potential serious developmental impacts of radiation exposure at that stage. Therefore, the correct answer is opption B.
Step-by-step explanation:
The question pertains to scenarios requiring immediate notification of the AFMOA/Bioenvironmental Engineering Division due to certain radiation exposures. Among the options provided, the scenario which requires immediate notification is B. dose to the embryo/fetus of 500 mrem.
This is because exposure to radiation, particularly for an embryo/fetus, can have serious developmental impacts, and the threshold for mandatory reporting is typically lower than for adults. Understanding radiation safety protocols is crucial in environments where radiation exposure can occur, such as nuclear power plants, medical facilities, and research laboratories.
Health effects of radiation exposure can range from minor to severe, with doses above 600 rem being fatal. It is essential to monitor and control radiation exposure to prevent long-term health risks like cancer or genetic changes. Radiation doses to the public are heavily regulated and are set at much lower levels than occupational limits to ensure safety.
