Description
This report describes an improved instrument to detect radiation that would be emitted by the accidental assembly of a critical mass of fissionable material. The instrument is a solid-state model designed to supersede a vacuum-tube-circuit model that has been in use for several years. The new instrument provides audible and visible alarms within 4 seconds after exposure to gamma radiation exceeding 1 R/hr. The instrument alarms within 0.3 second after exposure to a 50 microsecond burst of radiation that induces a dose of 0.6 mR
