| 中文摘要 | 介绍了应用152Eu面源对就地计数系统(ISOCS)小推车车体屏蔽修正的实验方法和计算方法。BE5030型HPGe探测器配带50 mm-90°、50 mm-30°或50 mm-180°铅准直器,端面向下,垂直地面测量,探测器距地面58.2 cm。得到了该测量条件下关注能量γ射线的小推车屏蔽修正因子。并通过最小二乘拟合得到屏蔽因子与γ射线能量的关系式,用以内插获得122~1 408 keV范围内任意γ射线的小推车车体屏蔽修正因子。; This paper presents the methods of experiment and calculation for shielding correction to the bodywork of in-situ object counting system(ISOCS) using a plane source of 152Eu.The shielding correction coefficients were obtained in the conditions that the HPGe detector of BE5030 with the collimators of 50 mm-90°,50 mm-30° or 50 mm-180°,and the detector distance 58.2 cm from ground surface.The relationships between the shielding correction coefficients and γ-ray energies were fitted by the least square method,for the shielding correction calculation of any energy within 122-1 408 keV by interpolation. |
