A study was done to determine the relative amounts of scatter for the following materials with atomic numbers ranging from Z=6 to Z=82: C, Al, Ti, Fe, Cu, Zn, Zr, Y, Mo, Ta, and Pb. Measurements were performed for each material on two constant potential x-ray units--one fitted with a molybdenum (Mo) anode-Mo filter and the other with a tungsten (W) anode-aluminum (Al) filter (medium filtration) at 30 kVp. Theoretical calculations were also performed for each anode to explain the scatter behavior and to aid in predicting the behavior for materials where measurements were not made. There was good agreement between the theoretical calculations and the experimental data.
开展了一项研究，以确定原子序数范围从Z = 6到Z = 82的下列材料的相对散射量：碳、铝、钛、铁、铜、锌、锆、钇、钼、钽和铅。对每种材料在两个恒压X射线装置上进行测量——一个配备钼（Mo）阳极-钼滤过器，另一个配备钨（W）阳极-铝（Al）滤过器（中等滤过），管电压为30 kVp。还对每个阳极进行了理论计算，以解释散射行为，并有助于预测未进行测量的材料的行为。理论计算与实验数据之间具有良好的一致性。
