Non-destructive Testing

["Poston, Jay (John) (HOU)" <jposton@guidant.com>]

We have a 12-inch cinder block wall that was supposedly filled with concrete
during construction.  I need to check for the presence of air pockets or any
other "weak" spots in the wall.  The facility will be handling large
quantities of P-32, so our main concern is bremsstrahlung.  Any suggestions
on the best way to test this wall?  Any recommendation on vendors who can
provide this service?

Thanks for your help,
