Samei, K.J. Kearfott, C.-K.C. Wang] This study introduces a new TLD reading technique to be adopted for low LET radiation field dosimetry capable of shallow and deep dose measurements which utilises simultaneously obtained integrated flow values from two sides of a hot gas-heated TLD slab. Time-dependent temperature profiles and the Randall-Wilkins TL model are utilised to simulate TL signal production. Assuming a given form for depth-dose distribution and TL light attenuation in the chip, the pair of integral glow values are used with the associated system of equations describing glow production to reconstruct the depth-dose distribution, from which shallow dose and deep dose may be estimated. The method is evaluated for a simulated LiF TLD irradiated in various radiation fields. For a 5% fluctuation in the response of the TLD, errors range from -4.4% to -13.5% for shallow dose and -2.6% to + 16.3% for deep dose.
