METHOD AND DEVICE FOR INSPECTING SPATIAL CONFIGURATION OF IONIZING RADIATION SOURCES IN CLOSED SPACES Russian patent published in 1994 - IPC

FIELD: measurement technology. SUBSTANCE: simultaneously with single-time visual control performed, intensity of radiation is measured in several control points, which are geometrically rigidly tied with surface of object. This set of points is subsequently used as standard one for comparing with corresponding values, which are achieved during tests according to identical order of measurements, but visual control is excluded in this case. Detection unit of the device is made in form of elastic, for example, cloth tape, onto which individual radiation detectors are disposed; they have fixed pitch and different amplitudes of output pulses. Amplitude analyzer is used as registrar, to input of which signals from all the detectors are applied simultaneously along the same cable channel. EFFECT: improved precision; improved reliability. 2 cl, 2 cl, 1 dwg
