^(60)Co源照射与感光仪曝光的X射线胶片特性曲线比较

Comparison between Characteristic Curves of ^(60)Co Irradiation and Photo Sensitometer Exposure X-ray Film

比较了60Co源照射与感光仪曝光X射线胶片的特性曲线。两者得到的特性曲线趾部与线性段均吻合较好,这些结果对今后在X射线照相中应用H-D曲线具有参考作用。

The characteristic curves of 60Co irradiation and photo sensitometer exposure X-ray film were compared.The characteristic curves obtained from both methods agreed well at the toe and linearity range.The results observed may provide reference for the application of H-D curves in X-ray radiography in the future.
