Abstract
The ARG-US radio frequency identification systems have been deployed at several DOE sites for field testing and applications since 2010. ARG-US utilizes battery-powered tags to remotely and continuously monitor the vital parameters of the tagged drum-type packages. The tags report the results to readers and the associated database via the 433-MHz radio frequency. No line of sight is necessary, and the tag read range can be >100 m. The tags are equipped with a versatile suite of sensors, including those for gamma and neutron radiation, temperature, humidity, seal and shock, for the specific monitoring tasks. The integrated gamma dosimeter and the neutron detector can provide comprehensive, real-time radiation monitoring in critical facilities. Any unexpected change in the radiation field can trigger an immediate alert, thus enhancing safety, security, and safeguards of the operation. The enhancements may reduce the need for routine manned inspections and thus minimize radiation exposure of personnel. This paper provides an assessment of performance and reliability of the ARG-US RFID system installed in the Alpha Gamma Hot Cell Facility (AGHCF) at Argonne since the summer of 2013.
