Zusammenfassung:	FIELD: flaw detection technologies. ^ SUBSTANCE: method includes inserting short-lived nuclide-emitter in form of liquid or gas into one or several hollows of product, placing films sensitive to radiation together with registering detectors outside on walls of hollow filled with nuclide, product images received on films are analyzed for detecting presence and location of flaws, then flawed portions are scanned and on basis of collimated detectors indications size of flaws is defined more accurately, and then nuclide-emitter is removed from controlled product. ^ EFFECT: higher efficiency.
