METHOD AND DEVICE FOR RADIATIVE MEASURING OF DENSITY OF SOLID BODIES Russian patent published in 2009 - IPC G01N23/06 G01N9/24 

FIELD: physics, measuring.

SUBSTANCE: invention concerns field of measuring of density of products with gamma radiation use. The essence lies in registering of backscattered radiation simultaneously in each of two channels of the detector and approximate function of a density function of radiuses of a start of quantums by exponential dependence. In relation to intensity of the account in two channels of the detector gain the integrated performance of impairment of backscattered radiation on radius on which bottom on the gauge diagramme of dependence of an integrated testimonial from of density at the given energy of radiation erect density of object of the control. The device contains scintillator in the two-channel detector, executed in the form of a disk from two rings of different diameters. The ring of smaller diameter in which the ring block of a radiation protection at which centre the gamma radiation radiant is disposed is interposed is interposed into a ring of greater diameter. Each of two ring scintillators is supplied by a ring pulse counting device. The radiant in the radiation protection channel has possibility to change a standing by means of the device of travel of a radiant.

EFFECT: increase of speed, accuracy and productivity.
