Subject: [EXTERNAL] [powernet] 4 DAC-hours in 7 Days

Quick Benchmark Question:

Duke Energy currently requires a whole body count or other follow up on any 
worker who exceeds 4 DAC-hours in a rolling 7 day period.  This is difficult to 
track and we are considering changing to require a whole body count or other 
follow up only when an uptake that might exceed 10 mrem.

QUESTION:  Do you know of a regulatory or other requirement that requires 
tracking 4 DAC-hours in 7 days?  (This requirement exists in the December 2009 
EPRI alpha Guidelines but NOT in the current Guidelines.)

Thanks in advance.
