Heat capacity of thermoluminescent dosimeters using an indium antimonide infrared detector.

摘要

Heat capacity variations in thermoluminescent dosimeter (TLD) populations have been experimentally quantified for the first time using an infrared detector. Consistent heat is applied to each sample from a TLD reader, and infrared transmission is characterized by an indium antimonide (InSb) photodiode to determine the heat capacity. Using this method, variations as high as 30% were observed among TLDs manufactured over a period of about ten years. Nearly identical trends were observed among different phosphor types (
