Abstract
Improved method and means for the detection of nitrogenous material or assaying of nitrogenous material in an object on the basis of nuclear resonant attenuation of 9.17 MeV .gamma.-rays. A target in form of one or several .sup.13 C pellets at least 25.mu. thick, or alternatively in form of a body that bears a composite thin film including at least one .sup.13 C layer not more than 1.mu. thick and at least one other substance that is capable of generating supplementary .gamma.-radiation for determining the non-resonant component of attenuation, is bombarded with 1.75 MeV protons to produce a source of 9.17 MeV .gamma.-rays. The target is placed on one side of the inspected object and a .gamma.-ray detector or an array of such detectors is placed on the other side and the total and non-resonant attenuation are read and evaluated.
