ABSTRACT:
A laboratory testing mechanism for determining conformance of an optical iation detector to prespecified time response requirements, comprising an electrically-operated shutter and a fast-moving rotary disc located between a radiation source and the detector under testing. Proximity switch associated with the disc provide electrical signals representing the time at which the window of the detector is initially exposed to the radiation source and selected elapsed time intervals thereafter.
