Abstract:

A radiac set ANPDR-69 for surveying areas contaminated with fissionable materials has been developed for use in the field under adverse environmental conditions. Eight prototypes have been constructed several of these have been subjected to environmental testing at Air Force Weapons Laboratory with generally satisfactory results. A scintillation probe, with pulse-height analysis, serves for selective detection of L X radiation or low-energy gamma radiation emitted by the contaminants or their daughters. A digital display indicates the counting rate in the pulse-height window. Design and development studies are discussed. Physical and operational characteristics of the instrument are described.
