Localization Of Gamma Radiation Sources

Abstract

The paper describes a method for acquiring and processing data concerned with a radiation situation in a pre-defined region of interest with a goal of localizing point sources present in the region. The acquisition underlies the robotic platform Orpheus-X4 equipped with a precise navigation module and gamma radiation detectors, a path planning involves Boustrophedon decomposition. The processing is based on the Gauss-Newton method, a contribution of the paper consists in a way to provide the method correct input data. Introduced algorithms were verified experimentally. Although not all sources can be found using the chosen equipment, in case of successful localization the accuracy is not worse than 0.1 m.
