What's the best SDF and source angle to make a radiography of the drilled holes flange of 6 inch body flanged valve
with ir-192 with the minimum image distortion of the holes.
Thanks so much the answer will be a great help.
That's going to be a hard shot to get. I'd consult a lvl 2 or 3 radiographer. I'm sure one works at your local inspection company. Source a few and get their opinions over the phone.
