Thermoluminescent dosimeter badges

A. Thermoluminescent dosimeter (TLD) badges used to provide a permanent record of the cumulative exposure to the whole body must be worn on the trunk (below the shoulders and above the hips) outside of clothing on the portion or area of the body nearest the radiation source. The dosimeter window must face out from the body. 

A dose meter or dosimeter is an instrument that measures radiation dose. Personnel dosimetry is accomplished with such devices as the film badge, thermoluminescent dosimeter, or pocket ionization chamber. In this way continuous recording of cumulative radiation dose can be maintained. 

A second type of badge detector is a thermoluminescence dosimeter that traps energy from radiation in a thermoluminescent material that releases this energy when it is heated. These detectors have largely replaced film badges because they are very sensitive and have a linear response over a wide range of doses as well as dose rates. 

External exposure can be measured by personnel monitoring using film badges or thermoluminescent dosimeters (TLD) in occupational and environmental monitoring, additionally, dose rate meters based on G-M tubes, proportional counters, scintillation detectors, etc., are introduced.

Thermoluminescent dosimeter A badge that contains a thermoluminescent chip worn by persons working with or around radioactive materials. 

A dosimeter is used to collect cumulative evidence of exposure to radiation and is worn as a badge. Dosimeters contain a thermoluminescent material such as lithium fluoride. Any incident radiation knocks electrons out of the flu-...
