Operating instructions for the gross gamma and iodine monitors at the Automatic Columbia River Monitoring Station
The Columbia River is used as a source of cooling water for Hanford Production reactors and as a source of irrigation and drinking water further downstream. The Automatic Columbia River Monitoring Station (ACRMS) houses instrumentation designed to provide continuous monitoring of Columbia River water for radioactivity and hexavalent chromium. The radiological monitoring system provides a continuous recording of the gross gamma and {sup 131}I levels in the river, an alarm for unusual activity levels, and an automatic emergency sampling system in the event of an alarm condition. This report describes the ACRMS -- the water pumping system, the radiological monitoring instrumentation, and the emergency capabilities. Although the station is designed to operate continuously and automatically, routine inspection and maintenance are required to assure proper functioning of all equipment. The following details provide general information on the operation and maintenance of the station and of the gross gamma and {sup 131}I monitoring systems. 3 refs., 6 figs.
