    Many, many years ago we developed an RT test for very basic evaluation of SCC.
    Used a piece of tube the same diameter and WT as the boiler tubes to be tested we had 10 x grooves machined longitudinally on the inside of the tube.
    That tube was then x-rayed.
    The reference graph then gave us 10 x different densities based on the different groove depths to compare with the depth of the SCC seen in the subsequent radiographs taken in the boiler.
    I know my story is of no help as you are talking about very advanced techniques, just thought I would share.
