METHOD OF RADIATION MONITORING OF WEIGHT CONTENT OF COMPONENTS IN ARTICLE Russian patent published in 1998 - IPC

FIELD: nondestructive inspection during radiation tomography of industrial objects. SUBSTANCE: article is irradiated with flux of ionizing radiation with relative movement of object and measurement system, radiation passed through article is recorded, tomograms are generated by computer and areas of interest are isolated. Mean values of linear coefficients of attenuation included in zones of tomograms whose dimensions correspond to isolated areas of interest are determined, additionally formed signal corresponding to external boundary of article which coordinates are used to find area of part of article included in area of interest. After this computation of weight content of component is conducted in agreement with proposed formula. EFFECT: increased precision of weight distribution of each component in article. 1 dwg
