What is the maximum permissible dose of radiation for dental workers during a year?

The maximum permissible dose of radiation for dental workers during a year is set at 5 rem. This limit is established to safeguard the health and safety of dental professionals who are routinely exposed to ionizing radiation, such as from x-ray machines.

The 5 rem limit aligns with guidelines provided by regulatory agencies and organizations such as the National Council on Radiation Protection and Measurements (NCRP) and the American National Standards Institute (ANSI). These organizations have implemented exposure limits to minimize the risk of radiation-related health issues, including cancer and other long-term effects.

Maintaining a limit of 5 rem helps ensure that dental workers can perform their duties while being protected from excessive exposure, contributing to a safer working environment. In contrast, the other options present higher limits that could lead to increased health risks, making them unsafe for regular occupational exposure in a dental setting.
