RE: Threshold



Rick,

Thank you for pointing this out to me.  I am probably not as familiar with

licensing termination as I should be.

  

Still, there is a threshold of 0.25 mSv for unrestricted and 1 mSv or 5 mSv

for restricted releases.  I wonder if any facilities have undergone license

termination under restricted conditions.

John-Public ALARA considerations are very much alive in the framework of

NRC's license termination process and rules (10 CFR 20, Subpart E).  The

criteria for both unrestricted and restricted release (10 CFR 20.1402 and

20.1403) stipulate ALARA demonstration conditions on the 25 mrem public

annual TEDE constraint.  Refer to NUREG-1549 "for the rest of the story."
