What is a key feature of optically stimulated dosimetry?

A key feature of optically stimulated dosimetry (OSLD) is that it allows for reading at any time post-exposure. This characteristic is significant because once the dosimeter is exposed to radiation, it can be stored for an extended period and read later without any loss of the measurement data pertaining to the accumulated radiation dose. The ability to read the dosimeter at a later time makes it versatile for various applications, including personal monitoring and environmental assessments, where immediate readout may not be possible or practical.

This feature distinguishes optically stimulated dosimeters from other types of dosimetry methods that may require specific conditions for readout, such as needing to be read immediately or within a restricted time frame after exposure.
