Stewart and others interested in this topic,
It seems that you are not aware about the tremendous research having been done on radionuclide uptake by wild animals in Europe - not only after the Chernobyl accident, but also long time before since the end of the fifties. There are excellent reports available
especially from Finland and Sweden, partly from Norway, but even from middle European countries like Austria. The research was extremely intensified during and after the Chenobyl accident.
The role of lichen in contamination of reindeer (you call it caribou, but they seem to be pretty much the same) and elks (you call them moose) is well researched. Lichen are widely used as bioindicators for all kind of pollutants, not only radionuclides. Finland has a long tradition of research. They were also used as indicators for Americium. You may google for "Timo Jaakola".
Wholebody counting of what you call lapplanders (they do not like this expression, but refer to themselves as "sami") has been done for many decades - google for "Tuula Rahola".
Thousands of pages (if not millions) of literature are available in the open literature. This literature is available mostly even on the internet. The USA were hardly contaminated compared to Europe (close to the then USSR) , so what to bother?
May I ask you and other RADSAFErs, why you always refer to single; unrepresentative US events when there is such a bulk of knowledge, reports, results and research available in Europe. I would agree that 100 years ago it was difficult to correspond across what we call the "big pond", but now there is telephone and internet. In case you regard it as criticism - yes, you are right!!!!!!
Best regards,
Franz
