Dear John,
  Nobody proposed any change in regulatory limits. The radiobiological evidence gives me confidence so that I shall not lose sleep over exposures of a few millisieverts.(Not withstanding genomic instability, bystander effects etc). The quibling over limits as low as 0.15 mSv or 0.25 mSv for the members of the public from waste storage facilities may be laughable. But when I look at the cost evaluation reported by GAO, I believe that all stakeholders including specialists must attempt to arrive at pragmatic limits.
  Probably refined radiobiological data give opportunity to spend money unwisely!

So, after all of the reading of papers, reviews and
rebuttals, what do you think will come of all this
work? Has anyone seen any indication that regulatroy
limits will be changed? 

P.S. Jim, I found the two papers you mentioned in
Radio. Environ. Biophys. and will read them later this
