[ RadSafe ] Chernobyl haunts the Norwegian uplands

I seem to recall that most of the Cesium-137 in the northern areas of Europe
(Laplands) (including Alaska and Northern Canada) was from the above ground
weapons testing performed by the Soviet Union and the United States in the
late 50's and early 60's. One can still find Stronium-90 and Cesium-137 in
'bones' of cattle and tree ash. A litle more than one half life has pasted
since then, so that they will be still in the soil and ground covering
vegetation. It will take several more half-lives before meat from these
animals will be safe. Has anyone thought of 'whole body counting' the
inhabitants to see what their uptake is especially the younger ones?
Just a thought!!
