Department of Energy January 25, 2011 – Federal Register Recent Federal Regulation Documents

The Department of Energy (DOE) proposes to revise the values in an appendix to its Occupational Radiation Protection requirements. The derived air concentration values for air immersion are calculated using several parameters. One of these, exposure time, is better represented by the hours in the workday, rather than the hours in a calendar day, and is therefore used in the revised calculations.
