METHOD TO IDENTIFY MATERIALS BY RADIOGRAPHIC RE-IRRADIATION

摘要

FIELD: physics. ^ SUBSTANCE: analysed objected is subjected to radiographic inspection at various angles to define attenuation coefficients of materials incorporated with said object. Note here that irradiation is performed at preset power levels and for preset materials to be identified. Possible error 6 in coefficient of attenuation is defined for every power level and every inclusion by means of computer program that corresponds to selected error 5. Thereafter, obtained data is processed by computer program to identify materials. ^ EFFECT: higher accuracy and reliability of identification. ^ 12 tbl
