With the advancement of technology, the performance of thermoluminescent dose readers is constantly improving.

The thermoluminescence dose reader is based on the phenomenon of thermoluminescence, that is, certain substances can store energy after being exposed to radiation. When these substances are heated to a certain temperature, the stored energy will be released in the form of light. Core components include heating systems, photomultiplier tubes, optical filters, and associated electronic measurement equipment. During operation, the thermoluminescent material irradiated by radiation is placed into the instrument and then gradually heated. As the temperature increases, the thermoluminescent material begins to emit light, and the luminous intensity is proportional to the radiant energy absorbed by the material.
