| 摘 要： | 新颁布的测定医用X线胶片感光度的国际标准规定 ,用X -射线作为感光测定曝光时的光源 ,此法精确 ,但所需设备复杂 ,操作耗时。因此 ,在日常的检测工作中 ,采用特定的可见光代替X射线作为感光测定时曝光的施照光 ,是实际而合理的方法。本文介绍一组绿色可见光 ,可适用于测定感绿医用X线胶片的感光度。

| Abstract: | The newly published ISO Standard for determining the speed of medical X-ray films specifies the use of X-ray beam for the exposure of the films during their sensitometric tests; though this method is precise,it requires the use of sophisticated equipment and time consuming operations.Thus,in routine tests,it is reasonable and practical to use specific visible light instead of the X-ray beam as the illuminant for sensitometry.This paper introduces a green light illuminant suitable for determining the speed of orthochromatic medical X-ray film. |
