Paper Abstract

High speed flash radiography has been used during the past few decades to record phenomena that occur during rapid dynamic events. The events are difficult, if not impossible, to record by other means due to the speed of the event or the obscuration associated with it. To eliminate the motion blur of objects moving in excess of 6,000 meters/sec (20,000 ft/sec), it is necessary to have an extremely short exposure time (5 to 70 nanoseconds). This short exposure time requires the use of high speed intensifying screens and high speed x-ray film to record the radiographic image. Technicians who use flash x-rays have to depend on recommendations from present and former flash x-ray users for film and screen selection. The film and screen industry has made many changes in the last few years. It is not uncommon to find that the particular film or screen you wish to use is no longer manufactured. This paper will describe some of the films and screens that are currently manufactured. It will describe their relative exposures when used with the Hewlett/Packard model 43731A 150 kV Flash X-ray System.
