What is the maximum permissible dose of radiation for an occupational worker in one year?

The maximum permissible dose of radiation for an occupational worker in one year is established based on various health and safety guidelines to minimize the risk of radiation exposure-related health issues. The value of 5 rem is in line with the recommendations set by organizations such as the National Council on Radiation Protection and Measurements (NCRP) and the Occupational Safety and Health Administration (OSHA).

This dose limit is designed to ensure that workers in environments where they might be exposed to radiological hazards remain within safe exposure limits while still allowing for the performance of their duties in these settings. It reflects a balance between the need for some level of occupational exposure and the importance of minimizing potential long-term risks, such as radiation-induced cancer or other health complications. Other values listed, such as 3 rem, 10 rem, and 15 rem, exceed or fall short of the established safety guidelines for occupational radiation exposure. Thus, 5 rem is recognized as the appropriate and standard limit.
