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。
The newly promulgated International Standard for Determining the Sensitivity of Medical X-ray Films, using X-rays as the light source for detecting light exposure, is accurate, but requires complicated equipment and time-consuming operation. Therefore, in the daily detection work, the use of specific visible light instead of X-ray as a light exposure when exposed to light, is a practical and reasonable method. This article describes a set of green visible light that can be used to determine the sensitivity of green-sensitive X-ray films.
