摘要：

True coincidence summing (TCS) correction factors were determined for Eu-152 volume sources used for gamma-ray efficiency calibration as the ratio of full energy peak efficiency (epsilon) simulated by MCNP5 code to the apparent full energy peak efficiency (epsilon(app)) determined experimentally. The results were compared to those calculated by TrueCoinc software and then validated using certified environmental radioactive samples. The dependance of Eu-152 and Ba-133 TCS factors on volume sample and matrix was investigated. Finally, as our n-type HPGe detector is very sensitive to low energy photons, the contribution of the gamma-X coincidence summing to TCS factors for Eu-152 and Ba-133 sources in volume soil samples was studied.
