Energy Absorption Coefficient for Concrete

[Erick Lindstrom <avrel@trex.oscs.montana.edu>]

Does anybody have a value Uen for "normal" concrete (2.35 g/cm^3)?  I've inter-
polated/integrated some values from info in Attix, Turner, RH Handbook, NCRP 49,
etc., and I want to compare with either published or individually calculated 
values. Are there any tables of concrete EACs available (for variable densities
of concrete)?

Thanks in advance...
