Texas Industrial Radiography Gamma Practice Test

What is the maximum annual whole body radiation dose for a radiation worker, if exposure limits are not exceeded?

1. 12 Rems

2. 1.25 Rems

3. 5 Rems

4. 500 millirems

The correct answer is: 5 Rems

The maximum annual whole body radiation dose for a radiation worker is established by regulatory agencies to ensure safety and minimize health risks from ionizing radiation exposure. The limit of 5 Rems (or 5000 millirems) is recommended for radiation workers, as it balances the need to protect individuals in occupational settings while allowing for the necessary work that involves radiation. This limit is rooted in research regarding the biological effects of radiation, which shows that doses above this range could increase the risk of long-term health effects, including cancer. By maintaining the exposure at 5 Rems, regulations aim to protect workers while also allowing for necessary exposures in various industrial and medical applications. Thus, the value of 5 Rems represents the accepted standard in occupational health and safety, specifically in the context of radiation exposure for workers in roles that involve handling or being near radioactive materials. This way, workers can perform their duties with a defined assurance that their exposure remains within safe limits.
