10 CFR 835 Update to Appendices

Effective 11 September 2017, the U.S. Department of Energy (DOE) is promulgating a final rule to amend values listed in two appendices to its current occupational radiation protection regulation. These are found in 10 CFR 835, Occupational Radiation Protection.

The amendment to Appendix C corrects the air immersion derived air concentration value for any single radionuclide not listed in the Appendix C table with a decay mode other than alpha emission or spontaneous fission and with radioactive half-life less than two hours, adjusted for an eight-hour work day. The amendments to Appendix E correct the activity information of two radionuclides, 102Rh and 102mRh.
