Method of focusing the gamma radiation emitted by a source and a device for implementing said method

摘要

A method for focusing the gamma radiation emitted by a source, characterized in that a liquid mass absorbing with respect to the gamma radiation is placed between said source and an apparatus for measuring the radiation emitted by it, being arranged inside said liquid mass a passageway for the gamma radiation emitted by the source, and, in at least a part of the rectilinear path between the source and the measuring apparatus, a filiform organ of material that is not very absorbent for gamma radiation, said organ remaining entirely contained in the liquid mass, the section and/or the length of the filiform organ and the thickness of the absorbing liquid mass in function being chosen, respectively, the first, of the importance of the surface of the radiated function and, the second, of the intensity of the radiation emitted by the source.
