[ RadSafe ] Thanks - Responses on US NRC Decommissioning Criteria

[Leo M. Lowe]

Many thanks to the several people who pointed me towards NRC's NUREG-1757 
for guidance on their decommissioning criteria (specifically,  the 
screening level soil concentrations for soil in Appendix H of Vol. 
2).  Your help is much appreciated.  The listed soil concentrations are 
generic, conservative values corresponding to 0.25 mSv/y (excluding radon) 
for a resident farmer scenario, and site-specific characteristics should be 
considered if the concentrations exceed these screening-level values.
