摘要
Abstract
The tissue equivalent proportional counters are used as active neutron dose‐meters in radiation protection .A spherical TEPC was designed and employed for moni‐toring accelerator‐based mono‐energetic neutron sources . T he microdosimetric spectra of 0.36 ,0.65 ,0.8 ,1.0 and 1.3 MeV mono‐energetic neutrons were obtained .The absorbed dose ,mean quality factor and dose equivalent value were evaluated from the measured spectra .The comparison between H* (10) which was calculated based on the transforming factor of fluence to ambient dose equivalent and measured dose equivalent was conducted for each mono‐energetic neutron .The FLUKA simulation of TEPC was also implemented for comparison .It is found that the simulated data agree well with the experimental results and both reveal a good dose equivalent response of the spherical T EPC .关键词
