What does the acronym "TLD" stand for in radiation dosimetry?

The acronym "TLD" stands for Thermoluminescent Dosimeter, which is a device used for measuring ionizing radiation exposure. TLDs work by utilizing certain materials that can store energy when exposed to radiation. When these materials are subsequently heated, they release this stored energy in the form of visible light. The intensity of this light is directly proportional to the amount of radiation the material was exposed to, allowing for accurate measurement and assessment of radiation doses received by individuals.

Thermoluminescent dosimetry is widely used in various fields, including medical radiology, occupational safety, and environmental monitoring, due to its sensitivity, accuracy, and ability to provide a permanent record of radiation exposure. These characteristics make TLDs an essential tool in ensuring that radiation exposure stays within safe limits and helps protect individuals from the harmful effects of excessive radiation.
