Measurement results of the relative contribution of primary and secondary radiation are presented. Measurements were done with both monoenergetic and broad spectrum x-ray beams. A variety of phantoms were used: graphite, water, lucite, a skull phantom, and aluminum. We found that the primary radiation fraction is nearly independent of photon energy and tube potential. Calculations using a simple single Compton scattering model agree with the experiment results.
给出了一次辐射和二次辐射相对贡献的测量结果。测量是使用单能和广谱X射线束进行的。使用了多种体模：石墨、水、有机玻璃、颅骨体模和铝。我们发现一次辐射份额几乎与光子能量和管电压无关。使用简单的单康普顿散射模型进行的计算与实验结果相符。
