Book Description
Design criteria were established following a survey among radiac specialists in the three services, and among Laboratory personnel and civil defense instructors. The resulting design includes these features: (1) A lowimpe ance circuit giving 20% accuracy from -40 to +50 C, with no zero drift; (2) A 50-cu in. belt-carried package which satisfied Mil-E-16400 environment specifications; (3) Gamma rate from 1 to 1,000 rad/hr, skin-dose rate to 5,000 rad/hr (from a separable probe), each indicated on several linear meter scales; and (4) A connector for a four-decade, low-range probe, and other possible auxiliary probes. Six prototypes have been fabricated. Work is continuing toward packaging the low-range probe and toward reducing costs of manufacture. (Author).

Book Description
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).

Book Description
A wide-range, multipurpose radiac of 20 percent accuracy has been developed for tactical military use. The instrument consists of a 2-lb, belt-carried package which measures gamma rate in three ranges to 1,000 rad/hr, and a "plug-in" probe to read skin-dose rate (beta + gamma) to 5,000 rad/hr. Provision is made to connect other special purpose detectors remote from the meter. The RGI-20 incorporates several other features unusual in Navy radiacs: a recycling ion chamber and low-impedance circuitry, a simplified scale-changing mechanism capable of switching 11 linear scales, and rechargeable batteries. This report presents construction and performance information.
