FIELD: measurement equipment.
SUBSTANCE: usage for radiation control of an object status. One performs transmission of an object with X-rays or gamma-rays, detector registration of intensity of the radiation having penetrated through the object and re-transmission. Re-transmission of the control object proceeds with the angle of the radiation beam incidence modified by a value from 0.5° to 10°. One registers intensity at re-transmission, compares distribution of radiation intensity across the detector surface in the both cases and estimates presence or absence of defects in the object based on match or mismatch of the relative positioning of the increased intensity areas.
EFFECT: enhanced authenticity of radiation control results including for complicated shape objects.
