Who is authorized to wear a personal monitor in a radiation therapy setting?

In a radiation therapy setting, personal monitoring devices are used to measure the exposure of individuals to ionizing radiation during their work activities. The correct option indicates that personal monitors should only be worn by the individual to whom they were issued. This is crucial for several reasons.

First, personal monitors are calibrated and assigned to specific individuals to accurately track their individual exposure levels throughout their workday. This ensures that any recorded radiation exposure is directly attributable to that person, allowing for precise monitoring of accumulated doses against regulatory limits and health guidelines.

Additionally, the data collected from personal monitors can be important for ongoing health surveillance and safety protocols. Allowing others to wear a monitor that does not belong to them can lead to inaccurate readings and misrepresentation of individual exposure levels, which can ultimately compromise safety protocols and lead to potential regulatory violations or health risks.

Thus, personal monitors serve not only as a safety measure for the wearer's protection but also as a compliance tool for the facility's adherence to radiation safety regulations. Each individual's exposure must be managed and reviewed under their own monitoring device to ensure a safe working environment.
