Abstract
By using Monte Carlo MCNP5 program, we have researched 3mm tmcmness of prooe affects on de- tection efficiency and absolute detection efficiency. The main study results are as follows： the thicker of the steel tube of the detector,there are more counts of low-energy rays when 1.46MeV gamma-rays passing through the tube, the total counts of the photo-peak will decrease slowly, the absolute photo-peak detection efficiency will de-crease with the increase of the thickness of the tube of the detector.关键词
