First international intercomparison of image analysers

摘要

Image analyser systems used for evaluating solid state nuclear track detectors (SSNTD) were compared in order to establish minimum hardware and software requirements and methodology necessary in different fields of radiation dosimetry. For the purpose, CR-39 detectors (TASL, Bristol, U.K.) were irradiated with different (n,a) and (n,p) converters in a reference Pu-Be neutron field, in an underground laboratory with high radon concentration and by different ct sources at the Atomic Energy Research Institute (AERI) in Budapest, Hungary. 6 sets of etched and pre-evaluated detectors and the 7th one without etching were distributed among the 14 laboratories from 11 countries. The participants measured the different track parameters' and statistically evaluated the results, to determine the performance of their system. The statistical analysis of results showed high deviations from the mean values in many cases. As the conclusion of the intercomparison recommendations were given to fulfill those requirements necessary to construct an appropriate image analyser system for evaluating SSNTDs. [References: 11]
