Abstract :
The development of fluoroscopy as an inspection method and as an aid to radiography is discussed and the economics of both applications, their advantages and limitations, considered. A 150-kY mobile fluoroscopic x-ray unit and a 150-kY fine focus unit, which permits an enlargement of the image, are described. Typical users include light alloy foundries, electrical engineering and the food industry. Special problems of fluoroscopy are discussed, such as the protection and fatigue of the operator, and the subjective element which is introduced by the method.
