Which personal radiation monitor is based on stimulated luminescence?

The personal radiation monitor that is based on stimulated luminescence is the OSL (Optically Stimulated Luminescence) dosimeter. This type of dosimeter functions by incorporating aluminum oxide as its sensing material, which stores energy from ionizing radiation. When exposed to light, typically in the form of a laser, this stored energy is released as light, which can then be measured to determine the amount of radiation exposure the dosimeter has encountered.

OSL dosimeters are notable for their sensitivity and precision in detecting low levels of radiation. They can also be reused after the initial reading, as re-exposure to light can clear the signal, allowing for new measurements. The technology behind OSL dosimeters makes them a popular choice for radiation monitoring in various settings, including medical facilities and occupational environments where radiation exposure is a concern.

In contrast, thermoluminescent dosimeters (TLDs), while also used for measuring radiation exposure, rely on the light emitted when the material is heated, rather than being stimulated by light. Pocket dosimeters, on the other hand, provide immediate readings and function based on ionization principles, rather than luminescence. The distinction in how these devices operate highlights why OSL dosimeters stand out in
