An Exposure Meter for Radiography

Abstract

An exposure meter has been developed for use with all penetrating radiations harder than 100 kilovolt x-rays. The sensitivity may be varied to cover exposures from a fraction of a minute to 100 hours with type A film. A built in standard of calibration is provided to check quickly circuit adjustments, eliminating the need for highly stabilized circuits. The exposure meter utilized a simple type of intensity measuring circuit.
