摘　　要：通过使用X射线标准化辐射场、标准铅片和剂量率仪等设备,对国内不同地区6种常用烧结空心砖在(70-120)kV管电压条件下的铅当量进行研究。结果表明,烧结空心砖在(70-120)kV管电压条件下的铅当量范围为(0.39-0.79)mmPb;烧结空心砖的铅当量随管电压的增加出现先增加后减小的变化趋势,在管电压为90kV时达到最大;烧结空心砖的铅当量大小与自身结构相关,与表观密度大小无关。The lead equivalent of 6 kinds of commonly used sintered hollow bricks, from different regions of China, is studied at(70-120)kV tube voltage, by X-ray standardized radiation field, standard lead sheet and dosimeter. The results show that the lead equivalent range of sintered hollow bricks under the condition of(70-120)kV tube voltage is varying between 0.39-0.79mmPb. The lead equivalents of sintered hollow bricks increase to the maximum at 90kV and then decrease with the increase of tube voltage. The lead equivalent of the sintered hollow brick is related to its own structure,and has no clear correlation with the apparent density.
