What does TLD stand for in relation to radiation badge technology?

The term TLD in relation to radiation badge technology stands for Thermoluminescent Dosimeter. This is a device used to measure ionizing radiation exposure by utilizing the thermoluminescent properties of certain materials, typically lithium fluoride crystals. When these materials are exposed to radiation, they absorb energy and store it. Upon heating, they release this energy in the form of light, which can be measured and correlated to the amount of radiation exposure the badge has received.

TLDs are particularly valued in radiation monitoring because they provide accurate and reliable dose measurements over a wide range of radiation levels. They are commonly used in various fields, such as healthcare, nuclear energy, and research, to ensure that personnel are not exceeding safe limits of radiation exposure.
