Abstract


The speed and average gradient of standard films were measured by using sensitometer. First, We combined each four intensifyin
g screen with each film, and measured the density after developing Al step wedge by X-ray.
The results are as follows.
1. The speed of film exposured by blue light was highest in Konica AX film, but lowest in Agfa XP film.
2. The light exposured in rare earth fluorescent screen(Kodak Lanex) was green and the used film was regular type but the film density was rather lower
3. As the speed of film was lower, the width of latitude was higher, so how to choose film and proper speed are very important.
