FIELD: object investigations in dissipated or passed radiation. ^ SUBSTANCE: broad irradiating beam covering entire object to be investigated is used for inspecting this object with passed or dissipated penetrating radiation. Novelty is use of beam with time-variable radiation intensity distribution in its cross-sectional area ensured by moving screen heterogeneous for used radiation across beam. Resultant definition depends on penetrating radiation measurement quantization step upon interacting with object at essential increase in effectiveness of source energy use. ^ EFFECT: enhanced scan speed due to effective use of source power or reduced power of source at same scan speed. ^ 19 cl, 19 dwg |
