Miller, K; Kiyoi, G T

A wide-range, multipurpose radiac of 20% accuracy was developed for tactical military use. The instrument consists of a 2.5-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 a four-decade low range probe now under development, or 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 scalechanging mechanism capable of switching 11 linear scales, and rechargeable batteries. Construction and performance information are included. (auth)
