Which statement best defines a controlled area?

A controlled area is a designated space where radiation levels are managed and monitored to ensure the safety of individuals who may have occupational exposure to radiation. This area is typically defined by specific regulations and guidelines that delineate how radiation exposure is to be monitored and controlled.

The components included in the correct answer highlight important aspects of what constitutes a controlled area. Firstly, it is occupied by radiation workers trained in safety, indicating that individuals present in such areas must be knowledgeable about the risks and safety protocols associated with radiation. This training is crucial for minimizing exposure and ensuring safe practices.

Secondly, the mention of individuals wearing radiation monitors emphasizes the need for continuous monitoring of potential radiation exposure. These monitors help track the dose received by workers and alert them to any levels of radiation that may pose a risk to their health.

Lastly, the occupancy factor relates to the amount of time individuals are present in the controlled area, which is an important consideration when assessing potential radiation doses. An occupancy factor of 1 means that individuals are assumed to be in that area 100% of the time, which is a standard variable used in radiation protection calculations.

Together, these factors demonstrate the comprehensive nature of what defines a controlled area, where the emphasis is on the training, monitoring, and management of
