A Universal Exposure Calculator for Radium Radiography and its Application to Current Radiographic Films and Techniques
SourceThis paper describes an exposure calculator for radium radiography so designed and constructed as to permit its use as a standardized exposure calculator in connection with steel and other materials and with all types of industrial radiographic film, or with radiographic techniques which aim at image density levels higher or lower than the normal net density of 1.00. Its use requires a knowledge of the speed rating factors for the particular film and technique employed. The paper also describes the method of determining the film speed rating factors for use with the universal exposure calculator and presents data on the speed rating factors of a number of commercial types of radiographic film.
