Dose coefficients for unknown radionuclides

[Jean-Michel Mure <jm.mure@andra.fr>]

Dear Radsafers,


Setting up some new criteria for low level waste requires to determine the
potential impact of these radionuclides : Ar39, Ar42, Kr81, Kr85, Nb91,
Nb92, Gd150, Dy154, Ho163, Bi208, Po208, Po209, Es252. I cannot find the
dose coefficients (external and internal exposure) of these radionuclides
in the federal guidances 11 and 12.


Questions :


1. Why are these radionuclides not dealt with in the guidance ?

2. Are you aware of a reference where I could find these ?

3. Do you know if there is a way of calculating a dose coefficients for such
radionuclides ?

4. Who shall I contact (ORNL) ?


Regards,
