Determination of X-ray effective energy and absorbed dose using CaF2:Mn and LiF:Mg, Ti thermoluminescence dosimeters

The results of the X-ray effective energy determination using the energy dependence of the response ratio of two thermoluminescent dosemeters are presented. CaF2:Mn dosemeters with a large, and LiF:Mg, Ti with a much lower energy dependence, were used. The calibration factors were obtained by irradiating the dosemeters with 137Cs gamma rays, and their energy dependences were measured with X-ray beams with the known effective energies and also with the 241Am gamma ray source. The measured values, i.e. the energy calibration curves, were compared with the calculation using the ratios of mass energy absorption coefficients and pertaining uncertainties were discussed. The results show, that in addition to the determination of the X-ray effective energy, this method enables determination of absorbed dose in the specified material compensated for the systematic error due to the energy dependence inherent to each type of detector used.
