title: TEPC performance for a reference standard.
abstract: A portable tissue-equivalent proportional counter (TEPC)-based system was developed, which will be used as a reference standard in the neutron mixed field for radiation protection. In this paper, microdosimetry of the TEPC system was studied both in neutron ((252)Cf and (241)Am-Be sources) and gamma ((137)Cs and (60)Co sources) reference radiation fields. The measured neutron and gamma-dose equivalent rates were, respectively, compared with those of the reference ambient dose equivalent rate H(*)(10). And the measured microdosimetric spectra were compared with the Monte Carlo code FLUKA simulated results. All of the comparisons primarily agreed well.
