Comment on Draft Regulatory Guide, Applications of Bioassay for Uranium

The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment draft regulatory guide (DG), DG–8054, "Applications of Bioassay for Uranium." This guidance provides acceptable guidance for NRC licensees, for the development and implementation of a bioassay program that will monitor the intake of mixtures of the naturally occurring isotopes of uranium (234U, 235U, and 238U) by occupational workers. A bioassay is a determination of the kind, quantity, location, or retention of radionuclides in the body by direct (in vivo) measurement or by indirect (in vitro) analysis of material excreted or removed from the body.

Comments must be submitted by 5 December 2014. Comments received after this date will be considered if it is practical to do so, but the NRC is able to ensure consideration only for comments received by the submittal deadline.
