Thermoluminescent dosimeters (TLDs) contain crystals that absorb energy when exposed to radiation
Indicate whether the statement is true or false
True. TLDs contain lithium fluoride crystals which, when heated after exposure to radiation, give off energy in the form of visible light. The amount of light emitted is proportional to the amount of radiation absorbed by the crystals, making TLDs very accurate radiation monitoring devices.
