A device to measure nuclear radiation.
A personal dosimeter which uses solid crystals to monitor radiation absorbed dose. Typically, these crystals are composed of lithium fluoride (LiF) and exhibit radiation absorption characteristics similar to that of human tissue. The ionizing radiation produces small local crystal defects which are stable until the crystal is heated. When the crystal is heated to temperatures of approximately 200°C, the defects are removed and the associated energy is released in the form of light. The amount of light produced is proportional to the number of crystal defects induced which in turn is related to the amount of radiation absorbed.
A dosimeter made of a crystalline material which is capable of both storing energy from absorption of ionizing radiation and releasing this energy in the form of visible light when heated. The amount of light released can be used as a measure of absorbed dose.
crystalline materials that emit light if heated after being exposed to radiation.
Radiation monitoring device used to record the radiological exposure of personnel or areas to certain types of radiation.
A device that directly measures absorbed dosage. TLDs are sometimes used to verify the accuracy of radiation treatments.
A device that registers the radiation dose (energy per unit mass) indicated by changes in color induced by temperature change. A device that directly measures absorbed dose
A thermoluminescent dosimeter, or TLD, is a small device used to measure radiation exposure by measuring the amount of visible light emitted from a crystal in the detector when the crystal is heated. The amount of light emitted is dependent upon the radiation exposure.
