| Notes | 11-2566/TL According to the different characteristics of microdosimetric spectra measured by tissue equivalent proportional counter （TEPC）, the neutron dose equivalent and γ dose e- quivalent could be distinguished in a unknown neutron and γ mixed radiation field. In order to discriminate the γ radiation dose equivalent from the total value,the pure γmicrodosimet- ric spectra was measured in60Co, 137Cs radionuclide radiation field with TEPC. TEPC mi- crodosimetric spectra in a series of monoenergy γ radiation field were simulated by FLUKA code. All the 3＇ radiation microdosimetric spectra, including measured spectrum in 60Co, 137Cs radiation field and that of simulation spectrum by FLUKA code, reveal a trait that the linear energy of γ radiation is basically lower than 10 keV/tam. This trait is the very foun- dation to discriminate the γ radiation from the mixed radiation.
