Abstract This study investigated the series of proficiency testing held by the Institute of Nuclear Energy Research (INER) from 2010 to 2017 and the benchmark of one type of dose evaluation system for personnel dosimeters in Taiwan. Based on the latest American National Standard Institute/Health Physics Society (ANSI/HPS) N13.11–2009 (R2015) performance testing standard, the personnel dose equivalent, Hp(d) data of the proficiency testing programs were reanalyzed to research the dose assessment ability and the criteria update feasibility. The results showed that the tolerance level (L), absolute of bias (|B|) and standard deviation (S) for all categories of all the 8 laboratories and 4 types of dosimeter well met the latest ANSI/HPS N13.11 criteria. In addition, the measurements of the Hp(d) with LiF: Mg, Ti-based TLD personnel dosimeters were also demonstrated by comparing with the MCNP6 Monte Carlo code. The dose responses were satisfactory in M100, M150 X-ray and 137Cs (including the angle tests) beams produced by INER for radiation protection level application.
