Subject: Dose coefficients for unknown radionuclides


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,
