What is the maximum permissible dose (MPD) of radiation for dental personnel per year?

The maximum permissible dose (MPD) of radiation for dental personnel per year is established based on guidelines from authorities such as the National Council on Radiation Protection and Measurements (NCRP) and the Occupational Safety and Health Administration (OSHA). The accepted limit for occupational exposure for radiation workers, including dental personnel, is 50 mSv (5 rem) per year.

This established limit considers the balance between the necessary use of radiation in dental procedures and the protection of those who are regularly exposed to it. The MPD is designed to minimize health risks while allowing professionals to perform their duties effectively.

The guidelines ensure that dental personnel can maintain a safe level of exposure, significantly lower than the thresholds at which adverse health effects might occur. Regular monitoring and adherence to safety practices further help in staying within these limits.
