[ RadSafe ] Ag-108m Release Criteria

[Emer, Dudley (CONTR)]

Depending where you do the look up Ag-108m seems to be one of those with a wide range of reported half lives.
Earlier databases seem to favor 127 years while the newer databases cite 437 years, but they all agree that it has 4 high yield gammas.
As to why it's not in there I haven't a clue

Ag-108m is in the"old" Radiological Health Handbook Department of Health 
Education and Welfare, Public Health Service (DHEW/PHS) , 1970.  Its 
production is by Ag-107 (n, gamma).  Half-life is ~ 5 years.  It's EC is 90% 
and IT is 10%.  It has no gammas and that may be why it is not in that 
Library.

Anyone out there familiar enough with the DandD code to know why Ag-108m is
not included in the radionuclide library?  Am I missing something?
