Abstract : A plug-in module and detector are described which extend the range of the AN/FDR-502 Remote Reading Radiation Monitor and Alarm System from 100 mR/h down to background (10 to 15 microR/h). The detector, an 18504 Geiger-Mueller tube, is connected to the control console by a single-core screened cable which can be up to 500 feet in length. (Author)
