FIELD: measurement equipment.
SUBSTANCE: penetrating radiation is generated, filtered and subsequently sent via a control object, and the passed-through radiation is registered, at the same time the generated penetrating radiation is gamma radiation of thulium Tm170 isotope, and for filtration tungsten or tantalum is used with efficient thickness from 0.2 to 0.5 mm.
EFFECT: reduced complexity of equipment and its energy intensity with simultaneous increase of sensitivity to defects.
