Laboratory results of personal dosimetry in international comparative measurements

Between 2015 and 2017, the SLM Personal Dosimetry Workshop participated in two international comparisons organized by EURAGOS Group WG2. The first comparisons (IC2015ext) were aimed at determining an equivalent dose in the skin using limb dosimeters. 52 organizations with 72 dosimetric systems participated in the survey. In the second project (IC2016ph), which was designed to measure the personal dose equivalent of Hp (10) and Hp (0.07), we used a new LBG 01H1H0 type with a TLD 100H chip (LiF:CuP) in 8850 enclosures and measured at new counter of our HARSHAW 6600 Plus Laboratory. 88 organizations with 103 dosimetric systems participated. The results of both comparative measurements confirmed the accuracy of the dosimetry system calibration and evaluation procedures used in the SLM Personal Dosimetry Laboratory. (authors)
