COMPARISON OF DIFFERENT DOSE ALGORITHMS USED TO EVALUATE A TWO ELEMENT LiF:Mg,Ti TL PERSONAL DOSEMETER

Description

Overview: This paper presents the results of a comparison of three different dose algorithms used for evaluating a two element TL routine wholebody dosemeter. Due to the energy response of the LiF:Mg,Ti detectors a dose algorithm is necessary to assess the relevant dose over the rated energy range with an acceptable energy response. The three different discussed dose algorithms are designed to calculate the dose for different dose quantities. The initial algorithm is used to evaluate the dose quantity photon dose equivalent Hx. This quantity was the legal quantity in Austria and Germany for of the last decades. The recent two algorithms are designed for reading out the dosemeter in the dose quantity personal dose equivalent, Hp(10) and Hp(0.07). A huge number of individual dose values are recalculated and compared by statistical methods. In addition all dose values are analysed with respect to the ratio of the two detector readings which adds some spectral information to the dose values. This allows estimating the radiation quality (photon energy) for the different dose values.
