The RGI-20 Radiac System - A Wide Range Beta-Gamma Instrument. II. The Solid State Pulsed GM Tube Low Range Accessory Probe,
Abstract
A plug-on low range accessory, consisting of a main unit and a cable-connected probe has been developed for the RGI-20 radiac system. The solid state circuit for pulsed GM tube operation is contained in the main unit whose dimensions are approximately 2 x 2-1/2 x 6 in. The GM tube is ounted in a cable-connected probe with side and end beta window provisions. Ranges covered by the unit are 0-1, 0-10, 0-100, and 0 1000 millirad/hr; temperature affects accuracy by less than =20% from -40 to 50 C. The operating power, rate-computing circuit, and scale-changing meter display are provided by the basic high range (0-1000 rad/hr) RGI-20 module. (Author)
