| 中文摘要: |
| 以222Rn累积浓度的测量为研究对象,采用蒙特卡罗模拟方法,研究了圆筒形固体核径迹探测器的探测效率与圆筒体高度、固体核径迹片尺寸和形状之间的关系。研究结果表明:1)当圆筒形探测器半径和固体核径迹片尺寸一定时,圆筒形探测器的固有效率、击中效率以及总探测效率均随着探测器高度的增加而减小;2)当圆筒形探测器尺寸一定时,击中效率随着圆形固体核径迹片的半径增大而减小,固有效率和总探测效率会随着固体核径迹片半径的增大而增加;3)当圆筒形探测器尺寸和固体核径迹片面积相同时,采用圆形固体核径迹片的探测器和采用方形固体核径迹片探测器的固有效率基本相同,但前者的击中效率以及总探测效率明显都高于后者。 |

| Taking the measurement of 222Rn cumulative concentration as the research object, the relationship between the detection efficiency of cylindrical solid nuclear track detector and the height of cylinder, the size and shape of the solid nuclear track sheet was studied by Monte Carlo simulation. The results show that:(1) when the radius of the cylindrical detector and the size of the solid nuclear track sheet are fixed, the intrinsic efficiency, hit efficiency and total detection efficiency of the cylindrical detector decrease with the increase of the detector height; (2) When the size of cylindrical radon detector is fixed, the hit efficiency decreases with the increase of the radius of circular solid nuclear track sheet, and the intrinsic efficiency and total detection efficiency increase with the increase of the radius of nuclear solid track sheet; (3) When the size of cylindrical detector and the area of solid nuclear track sheet are the same, the intrinsic efficiency of detector with circular solid nuclear track sheet and detector with square solid nuclear track sheet are basically the same, but the hit efficiency and total detection efficiency of the former are significantly higher than those of the latter. |
