METHOD AND DEVICE FOR DETERMINATION OF DENSITY AND SIZE OF OBJECT AND THEIR USE FOR INSPECTION OF NUCLEAR FUEL TABLETS IN PRODUCTION PROCESS Russian patent published in 2009 - IPC G01N9/24 G21C17/06 

FIELD: physics.

SUBSTANCE: invention relates to the area of non-destructive testing methods. Device for automatic density determination of object (100) includes device (2) for determination of significant size x of specified object (100); device (30) for determination of photon beam intensity (I) weakened due to passing through specified object (100); device (200) for data collection, processing and analysis, transportation means (70, 72, 80, 82, 84, 86, 88) for object (100); the first regulator of (74, 76, 78) object position (100); the second regulator of (90, 92, 94, 96, 98) object position (100). Method of the above device application includes calibration stages of device (2) and device (30) and stages of actual significant size measurement for object (100), which are performed for each object (100) in specified batch of objects.

EFFECT: increase of measurement accuracy.
