Abstract
An orientation detector for radioactive sources is provided. Such detector comprises a homogeneous sphere containing six sensors arranged on three different diameters at a limited depth from the sphere surface. Comparison of the radiation received and differently attenuated by the material of the sphere makes it possible to deduce the angular disposition of the source relative to the detector.
