What type of protection is prescribed in Title 10, CFR, Part 20?

The correct answer pertains to the prescribed standards for radiation protection. Title 10 of the Code of Federal Regulations (CFR), Part 20 establishes comprehensive regulations aimed at ensuring the safe use of nuclear energy and materials, particularly focusing on minimizing radiation exposure to individuals and the environment. This regulation outlines the permissible dose limits, monitoring requirements, and safety measures designed to protect workers, the general public, and the environment from the harmful effects of ionizing radiation.

In the context of the other options, fire safety regulations cover the requirements for preventing and responding to fires, often addressed in distinct regulations like NFPA standards, and are not included in Title 10. Environmental protection guidelines would fall under different regulatory frameworks, such as those administered by the Environmental Protection Agency (EPA), rather than Title 10. Finally, explosives handling procedures are specified under different titles and parts tailored for ordnance and munitions safety rather than the radiation-focused guidelines of Title 10, CFR, Part 20.
