What is a Planned Special Exposure (PSE)?

A Planned Special Exposure (PSE) refers to an additional authorized exposure that is distinct from the standard annual dose limit set for radiation workers. In certain situations where work tasks require the potential for increased exposure to radiation, a PSE can be designated to allow for this additional radiation exposure under specific regulatory guidelines and safety protocols.

The authorization for a PSE is typically required to ensure that the situation is clearly justified and that all safety measures are in place to protect the worker's health. This could apply, for instance, during emergencies, special projects, or when handling materials that necessitate higher exposure levels for a limited time.

In contrast, the other options describe concepts that do not align with the definition of a PSE. Scheduled exposures above the annual dose limit can exist but require careful justification and controls, while a temporary job role that involves no radiation does not pertain to exposure limits. Lastly, routine safety measures for all workers are preventative actions that maintain safety in all situations, rather than addressing a specific, planned increase in exposure.
