Occupational radiation monitoring is required when an individual is likely to receive more than which fraction of the annual dose limit?

Occupational radiation monitoring is mandated when an individual is likely to receive more than one-tenth (1/10) of the annual dose limit set by regulatory authorities. This requirement is in place to ensure the safety and health of workers who may be exposed to radiation in their jobs. By monitoring individuals who exceed this threshold, employers can take necessary precautions to reduce exposure and protect the workforce from potential health risks associated with radiation.

This standard allows for early detection of excessive exposure and facilitates appropriate interventions to reduce doses and manage workplace safety effectively. Other options represent higher fractions, which do not trigger the same level of required monitoring, thereby maintaining a balance between safety and practicality in occupational settings.
