[MW:709] RE: 708] re radiography bunker

It depends on various factors, what type of bunker you want built. (i.e
with concrete, sand bags, or steel etc.),

TVT value for each of the above are different, hence thickness of wall
may vary dpend on the max Ci of source you use,

Dimensions of the bunker you can slelect depend on the max dimensions of
the item you want to radiograph.
Assuming Safe radiation for human being@ 0.0075 mSv / hr, for Ir192
100Ci source you may need 50cm thk wall of concrete (RCC) aprx..
