| 摘 要： | 目的：研制适用于医学诊断X线摄影被检者照射量监测的电离室，并对其各种输出特性进行实验测量研究。材料与方法：整个电离室采用平行板电极，收集电极采用静电喷涂石墨电极，即不会在胶片上形成影像又不增加电离室对射线采吸收。结果与结论：所研制的电离室对有用X线束吸收少，其信号输出与输入线量强度及照射野面积呈良好线性，且线质响应均匀。

| Abstract: | purpose: The dose area product ionization chamber was developed and its properties were researched. Material and methods: In order to eliminate the image formed by the chamber. the electrodes of chamber were arranged in parallel and made of carbon. Result and conclusions: There is a good linearity between its signal output and exposure, irradiating field. The beam quality dependence is uniform. |
