Which monitoring devices do radiographers use to record monthly exposure to radiation?

The optically stimulated luminescent (OSL) dosimeter is widely recognized in radiation safety for its accuracy and reliability in monitoring exposure over time. OSL dosimeters utilize specific materials that respond to ionizing radiation by storing energy which can then be released as light when stimulated, allowing for a precise measurement of the radiation dose received.

They are particularly effective for measuring low levels of radiation and can provide detailed personal dose records. OSL dosimeters can easily be read multiple times and have a wide range of detection capabilities, making them ideal for regular monitoring, particularly in occupational settings like those for radiographers.

In contrast, while film badges also record exposure, they are less sensitive than OSL dosimeters and can suffer from environmental effects that might compromise their accuracy. Personal electronic dosimeters offer real-time measurements but may not be used for the same monthly cumulative assessment purposes as OSL dosimeters. Radiation film, though useful in some applications, is not commonly utilized by radiographers for individual exposure recording in the same manner as OSL dosimeters.
