Abstract
No Screen Film are used mostly for the Industrial examination of the penetration of X-rays. When the fluorescent intensifying screen is not used, an increase in sharpness is generally aequired ; high energy X-rays or gamma rays are used to increase the penetrability. There the image is apt to be flat ; the property of No Screen Film, i.e., high gamma rays and high density are needed to satify the conditions of this type of radiography. Its practical application in medicine to investigate a detailed image and its field of application was studied as well as the properties of the film.
