Request for Ir-191 Shielding Reference

["Michael P. Grissom" <mikeg@SLAC.Stanford.EDU>]

Radsafers,

An old colleague of ours has an immediate need for a
copy of one of the "gold standard" reference papers
in the shielding business.

If anyone has a copy at hand that could be faxed please 
let me know, the document requested is:

Ritz, V.H.:  "Broad and Narrow Beam Attenuation of
Ir-192 Gamma Rays in Concrete, Steel, and Lead."
Non-Destructive Testing, Vol. 16, p. 269, 1958.

This is an item getting tough to find even in the
most complete engineering library so any assistance
will be appreciated!

S.,

MikeG.
