I was recently reading the paper by Richard B. Firestone and William Topping, " Evidence of a Nuclear Catastrophe in Paleoindian Times", Mammoth Trumpet, Volume 16, Number 2, March 2001 reprinted in Infinite Energy Volume 7, Issue 40, November/December 2001 which details radioactive dating issues with such sites.
This particular article deals with the details of a presumed redating of a Michigan site, the site, which with other Northeastern sites seems to have anomalous dating issues where the Carbon 14 seems to perhaps have a "reset" which makes the artifacts appear to be younger than other evidence would indicate. Presumably a Supernova could have bombarded the region with an intense neutron flux which altered the various nuclear clocks used in dating. The article discusses the various mechanisms that may have been involved. A particular remnant of a Supernova is noted to exist in the Northern skies which could have supplied the needed event for such a resetting of nuclear clocks.
The article can be taken as a caution in using nuclear clocks in general as they are seemingly so sensitive to both Supernova and Solar radiation. Finding a less sensitive means seems unlikely, perhaps greater sophistication will counter that. Integrating a greater database and refined techniques of analysis will I hope make the use of such nuclear clocks more instructive in the future.
