When is a DLR typically issued to a worker?

A dosimeter, or DLR (dosimeter reading), is typically issued by the Radiation Protection (RP) Dosimetry Group as needed. This means that the issuance of a DLR is based on specific requirements and conditions, rather than being a routine or automatic process. The RP Dosimetry Group monitors radiation exposure and can determine the necessity of a dose reporting device based on an individual's work conditions, the nature of their tasks, and their exposure potential.

In practical terms, it's essential for radiation workers to have their DLR issued based on the current conditions they are facing. This ensures they are equipped to monitor exposure accurately when they are in environments where radiation is present. The accuracy and relevance of radiation monitoring are critical to ensuring that safety protocols and regulatory requirements are adhered to.

In contrast, the other options suggest routine issuance that wouldn't necessarily align with the operational practices of radiation safety management.
