An Automatic Remote Radiological Monitoring System which was developed was installed in a community and tested for operational characteristics. The system as delivered was capable of being operated via landline telemetry links but considerable engineering effort was required to effect an interface with a VHF radio link. Extensive modification of both the base station and remote station transceivers as well as the monitoring equipment was performed. When the radio telemetry problems had been solved, the system was deployed in Montgomery County, Maryland, which comprises an area of approximately five hundred square miles. The units were installed on County School properties distributed throughout the County, and the deployment pattern includes path lengths ranging from three and one half to fifteen and one half miles over rolling terrain. Telemetry modes successfully employed in the installation include two VHF single frequency radio links, six standard leased landline links, one combination leased landline - Bell System Audio Carrier link and one combination leased landline - duplex microwave link. The system is now operational and is currently being evaluated, under a separate contract, for effectiveness in its present form and for improvements in reliability and operability that may be incorporated in future systems.
