If cobalt and nickel are nearly equal in their absorption characteristics, you could use the nickel penetrameter instead of cobalt. If you cannot access the data, you could take a radiograph of the cobalt object and a nickel block of the same thickness and see the density. If the density is comparable, you could go ahead.

This is in regard to the aerospace industry. ------------ End Original Message ------------ Follow Ups: Post a Followup: Name: E-Mail: Subject: Comments: ----------- Start Original Message ----------- : Susan, : Since I lack ready access to radiographic equivalents of different materials, I would request you to do that search.
