Where must a single personnel monitoring device be located?

The correct placement of a single personnel monitoring device is crucial for accurately measuring radiation exposure. A monitoring device located outside the apron at the collar level is optimal because this position is generally where exposure is highest during fluoroscopic procedures. The collar area is often less shielded compared to the rest of the body when protective aprons are worn. As a result, monitoring at this level effectively reflects the exposure that the healthcare worker experiences during their practice.

Placing the device outside the apron ensures that it captures the radiation dose received directly on the body rather than being shielded by the apron. This monitoring practice is essential for adhering to safety protocols and for accurately assessing radiation exposure levels for regulatory compliance and personal health safety.
