According to OSHA, what is the maximum allowable annual radiation exposure for healthcare workers?

The maximum allowable annual radiation exposure for healthcare workers is established by OSHA and is set at 5 rem (roentgen equivalent man). This limit reflects the balance between the need for medical professionals to perform duties that may involve exposure to radiation and the necessity of ensuring their safety and wellbeing. The 5 rem limit is designed to minimize the risk of radiation-related health issues such as cancer or other potential effects linked with high levels of exposure.

This standard is based on extensive research regarding the biological effects of radiation and is aligned with guidelines from organizations such as the National Council on Radiation Protection and Measurements (NCRP) and the International Commission on Radiological Protection (ICRP). The limit is set to protect workers while allowing them to perform necessary medical procedures that involve radiation, such as imaging or radiation therapy, effectively.
