GAMMA-STEREOSCOPY DEVICE Russian patent published in 1997 - IPC

FIELD: examination and analysis of materials. SUBSTANCE: device allows measurement of distribution of intensity of gamma-photons Compton-scattered along quasi-unidimensional beam of probing photons. To this end, use is made of multi-detector system of nonspectrometric counters in function of scattered radiation recorder. System is oriented in direction of probing photon beam which ensures maximum geometrical aperture ratio when recording the scattered radiation. EFFECT: usage of three-dimensional defectoscopic information instead of two-dimensional one. 3 cl
