A method for determining the distribution of a radioactive material in a medium is provided which comprises the steps of: (a) providing a plurality of radiation detectors at a set of predetermined locations, each of said detectors producing an electrical output indicative of the amount of radioactive material in the vicinity of the detector; (b) moving the medium containing the radioactive material and the plurality of radiation detectors relative to one another so as to position the medium relative to the detectors at each of a set of predetermined positions; and (c) recording the electrical output of each of the detectors at each of the predetermined positions. Apparatus for practicing the method is also provided.
