thermoluminescent dosimeter
Quick Summary
A thermoluminescent dosimeter (TLD) is an instrument used to measure exposure to ionizing radiation. It utilizes crystalline materials that trap electrons when exposed to radiation.12
When the TLD is heated, these trapped electrons are released and recombine, emitting light. The intensity of this emitted light is proportional to the amount of radiation the material absorbed, allowing for the measurement of the accumulated radiation dose. This process effectively "resets" the dosimeter, making it reusable. Lithium fluoride is a common material used in TLDs due to its tissue-like atomic composition and ability to retain trapped charges over time.23

dosimeterThermoluminescent dosimeters are nonmetallic crystalline solids that trap electrons when exposed to ionizing radiation and can be mounted and calibrated to give a reading of radiation level. The ion-chamber dosimeter, like the thermoluminescent one, is reusable, but it is self-reading for immediate determination of exposure.
