| 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 (... |
