Re: Translocation Classification for Radionuclides
Erik,
If you need to make material-specific measurements (instead of using the chemical compound to assign the translocation class), one recent paper that I have seen --which was also for uranium-- is in Health Physics in 1997. I do not know whether the NRC agreed with the licensee's use of this method (it may not have been specifically reviewed by us). Also, I do not believe that NRC has any specific analytical procedure that must be followed (though I am no longer in the uranium recovery program, where at least some of these measurements have been done).
Metzger R., D. Wichers, J Vaselin, and P. Velasquez. "Solubility Characterization of Airborne Uranium from an In-Situ Uranium Processing Plant." Health Physics, Vol. 72(3), pages 418-422. March 1997.
Good luck,
Duane.

In 10 CFR 20, Appendix B, Table 1, each radionuclide has different limits
for each translocation class (D, W or Y). How is the translocation class
determined?
We have been performing alpha spectroscopy analysis of uranium on air
filters for a client who now wants to know if we can test for the
translocation classification of the uranium present.
I assume there a specific regulatory analytical protocol for this
determination. Where could I find this procedure?
Is this a highly specialized test that we should subcontract, or a test
that a fully equipped lab could handle?

If you're not part of the solution, you're part of the precipitate.
