Precision of Low-Dose Response of LiF:Mg, Ti Dosimeters Exposed to 80 kVp X-Rays

The low-dose response of a LiF:Mg, Ti thermoluminescent dosimeter (TLD- 100) was studied by exposing the TLDs to 80 kVp X-rays to different doses. There was no evidence of non-linearity in the dose range studied. The standard deviation was less than 10% at 0.3 mGy, the lowest thermoluminescent (TL) dose before the uncertainty in the TL reading became very large, which reached approximately 60%.
