What is the external dose threshold that requires enrollment into the dosimetry program?

The threshold for requiring enrollment in a dosimetry program is typically set at 100 mrem (millirem) per year. This limit is designed to monitor and ensure that individuals who may be exposed to ionizing radiation due to their work can have their exposures tracked appropriately.

It is crucial for workers in environments where radiation exposure is a possibility to be enrolled in a dosimetry program to assess their individual doses accurately and to implement necessary safety measures. The 100 mrem threshold reflects a balance between ensuring adequate monitoring for anyone who may have significant exposure while considering the overall goal of keeping radiation exposure as low as reasonably achievable (ALARA).

By requiring enrollment at this level, facilities can maintain a more rigorous oversight of radiation safety practices and help protect staff from unnecessary health risks associated with radiation exposure. Levels above this threshold may indicate a need for additional protective measures or modifications to work practices, further emphasizing the importance of diligent monitoring through a dosimetry program.
