What exposure level mandates that an individual should have a radiation badge?

The requirement for an individual to wear a radiation badge is typically triggered at exposure levels that reach or exceed 10% of the occupational dose limit. This serves as a safety precaution to monitor radiation exposure and ensure that it remains within acceptable levels. The badge helps to track the cumulative dose over time, thus allowing for appropriate safety measures to be implemented if exposure levels rise.

The threshold at 10% is rooted in regulatory guidance, which emphasizes the importance of monitoring workers who are exposed to radiation as part of their job. It helps in maintaining a safe working environment and complying with safety standards set by organizations concerned with radiation safety. By using a badge, health physicists and safety officers can effectively assess and manage the radiation safety program within the facility.

Other exposure levels mentioned do not reflect standard practices for monitoring. The thresholds set at 5%, 15%, and 20% are either too low or too high for the initiation of badge use according to commonly accepted guidelines.
