HVL and TVL values

[Peter Fundarek <P.FUNDAREK@utoronto.ca>]

Thanks to all who responded to my request for HVL and TVL values.  I 
shall be getting back to some of you personally for more information. 
 As was pointed out in some of the replies, I should have stated in my 
original post that the intention was to use lead as the shielding 
material in a point source configuration.  The values are intended to 
provide some general information on the shielding for specific 
radionuclides.

Thanks again to all who responded.
