The Model 955A is a single-channel area radiation monitoring system capable of operating over the ranges of 10-2 to 103 mR/h, 10-1 to 104 mR/h, or 100 to 105 mR/h, depending on the detector selected. The system monitors gamma radiation over a 5-decade range and provides indication when the radiation level decreases below a fail threshold, exceeds a warn set point, exceeds a high set point, or exceeds an overrange set point.

Applications
Area monitoring is used for the detection of x-ray or gamma radiation in a selected area. The monitor should be used in any location where personnel may be exposed to an adverse amount of radiation. Applications include nuclear reactors, accelerators, hot cells, irradiators, and any area where radiation sources are handled. These monitors can be used as single channel monitors or grouped together as a multichannel area monitoring system.
Universal Digital Ratemeter
The Model 956A-201 UDR, when connected to a Model 897A Series GM Detector, comprises a monitoring system which operates over a five decade range. The UDR provides display, control and annunciation functions for the monitoring system, and will display readings in the range of 10-2 to 105 mR/h.
