In radiography, the maximum permissible dose for occupational exposure is defined by which regulatory body?

The maximum permissible dose for occupational exposure in radiography is defined by the Nuclear Regulatory Commission (NRC). The NRC is responsible for regulating the use of radioactive materials and ensuring that workers are not exposed to excessive levels of radiation. They establish safety standards and permissible exposure limits in order to protect the health and safety of individuals working in environments where radiation is present.

The Occupational Safety and Health Administration (OSHA) does oversee workplace safety, including certain aspects of radiation safety, but it primarily focuses on general workplace safety standards rather than specific guidelines for radioactive exposure limits. The Environmental Protection Agency (EPA) deals mainly with environmental concerns related to radiation and pollution, while the American Dental Association (ADA) provides guidelines and recommendations for dental practices but does not establish regulatory dose limits. Thus, the correct body that sets these standards is indeed the NRC.
