Which of the following is a key focus of 10 CFR Part 20?

The emphasis of 10 CFR Part 20 is on establishing the standards for radiation protection for individuals who may be exposed to radiation in the workplace. This regulation outlines specific limits on occupational radiation exposure to protect workers from the potential harm that can result from ionizing radiation. The guidelines include annual dose limits, as well as considerations for monitoring, record keeping, and overall safety programs.

In the context of radiation safety regulations, the focus on occupational radiation limits serves to safeguard not just the health of workers but also to maintain safe environments in facilities where radiation is used, including hospitals, nuclear power plants, and research laboratories. This is key to ensuring compliance with safety protocols and minimizing the risk of radiation-related health issues among staff.

The other options, though related to radiation safety in some way, do not represent the primary focus of 10 CFR Part 20. Medical imaging protocols often relate more to clinical practice guidelines rather than occupational exposure limits. Fetal radiation safety is a specific concern under broader safety measures rather than a central theme of the regulation itself. Emergency evacuation procedures are essential for overall safety but fall outside the primary purview of occupational exposure standards detailed in 10 CFR Part 20.
