Personnel monitoring is required when it's likely an individual will receive more than what fraction of the annual dose limit for radiation workers?

Personnel monitoring is mandated when it is anticipated that an individual will receive more than 10% of the annual dose limit set for radiation workers. This threshold is established to ensure that individuals are adequately safeguarded against excessive exposure to radiation. The rationale behind monitoring at this level is rooted in the principles of radiation safety and the implementation of the ALARA (As Low As Reasonably Achievable) principle.

By monitoring personnel who may exceed this threshold, organizations can take proactive measures to mitigate exposure and ensure that radiation doses remain well within safe limits. This approach is critical for maintaining the health and safety of workers in environments where radiation is a potential hazard.
