ORAUT-RPRT-0081: Thoron Exposures at 

the Savannah River Site

 This report will demonstrate the appropriateness of a 

bounding approach based on tank farm air monitoring. 

Schedule delay due to non-uniformity in the thoron 

computation methodology. Generic methodology to 

be used for all sites is being published in ORAUT- RPRT-0084. ORAUT-RPRT-0081 is being revised to 

incorporate uniform methodology.
