There a still quite a few RBMK 1000's in operation.

Cs-137 originated from fallout from atmospheric weapon testing. C E Millier and Marinelli identified Cs-137 in human body for the first time in 1955.

It is worthwhile to collect data from the Chernobyl fallout; the way nuclear reactors are designed now with admirable safety features, there may never be another Chernobyl!!

  That's my recollection as well (Chernobyl-related).  I think it was the
Finns or Norwegians who discovered the cloud of high-level of radioactive
material 3 days or so after Chernobyl.  This was while I was at the IAEA and
it caused quite a stir among my Soviet colleagues.

Most of those area were in the path of the cloud that originated from
Chernobyl.  For a while the Finns were thinking of banning the eating of
caribou (raindeer??) due to the high levels of Cs-137 in the meat.

  Back at that time the approximate concentration of Cs-137 in undisturbed
soil due to fallout was less than about 1 pCi/g, assuming I remember
correctly of course.  That low a concentration would have been overwhelmed
by the Chernobyl fallout in those regions.

  The average resident of Kiev had a body burden of roughly 2200 Bq around
1999 (this from Dr. Perevashnikov of the Ukrain Institue of Radiation Safety
who was doing the measurements).

  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!!
