摘要
Abstract
A HPGe spectrometer was used to measure the established filtered X ray reference radiation of low kerma series and narrow spectrum series.A monte carlo model of measurement system was developed with the response matrix for 6 keV—305 keV simulated by energy interval of 1 keV and the fluence spectra was calculated by unfolding method.To verify the measuring and unfolding method,the mean energy,the first and second half-value layers and the energy resolution of the spectra were calculated from the fluence spectra and compared with the values given in GB/T 12162,the deviation was about less than 5%.The conversion coefficients from the air kerma to the ICRU operational quantities Hp（10）,Hp（0.07）,and H＊（10） were calculated using monoenergetic conversion coefficients at zero angle of incidence,which agreed well with the values given in GB/T 12162.关键词
