Hi Peter,

You might want to get your hands on the following document:

ORNL/RSIC-45/R1, Date Published - May 1982
"Specific Gamma-Ray Dose Constants for Nuclides Important to Dosimetry and
Radiological Assessment". by L.M. Unger & D.K. Trubey.  It should be available
from the National Technical Info. Service, U.S. Dept. of Commerce, 5285 Port
Royal Road, Springfield, VA  22161.  

It lists for approximately 500 nuclides, T 1/2's, photon energies &
probabilities, gamma factors, attenuation coefficients and last but not least
... Tenth Value Layers in SI units!  But, of course you Canadians are old hat
with that stuff !8*).

Does anyone know of a good source of information on the HVL or TVL 
values (prefer the latter) for individual radionuclides?  I am helping 
someone prepare some information sheets on radioisotopes and they 
require information on the HVL or TVL values for specific 
radionuclides.  They are looking at preparing these sheets for more 
than one hundred isotopes so it is not practical to repeat the list 
other than to say that it is all the isotopes generally of interest to 
health physicists.

Any information would be appreciated.
