GAMMA FLAW DETECTOR Russian patent published in 2010 - IPC G01N23/00 

FIELD: physics.

SUBSTANCE: proposed flaw detector comprises radiation protection with radiation source, collimator and radiation source drive. Note here that radiation source is arranged in vertical channel of tubular holder to be moved by its drive along holder vertical holder and, in the case of emergent drive failure, in vertical channel by gravity together with holder in storage position. Note that replaceable collimation inserts designed to vary radiation beam parametres are arranged in cylindrical stepped opening arranged perpendicular to source holder vertical axis.

EFFECT: higher safety, ease of use and all-purpose qualities of flaw detector.
