Franz,

It is still possible to measure Sr-90 in milk from milk producing states such 
as Wisconsin and Minnesota.  It is apparently present because the soil in 
those states still has Sr-90 from fallout.  Obviously some of that Sr-90 will 
be incorporated into the teeth of children.  It is an interesting fact that 
milk from Nevada has less Sr-90 than milk from mid-America, apparently 
related to the fact that the Sr-90 was removed from the atmosphere by rain, 
which seldom falls in Nevada.  Almost surely the Tooth Fairy Project will 
detect Sr-90 in teeth but I predict it will be almost entirely (perhaps even 
entirely) Sr-90 from the fallout of the 1960s. All the data point to the fact 
that fallout fission products are much more abundant in the enviroment than 
fission products from power plants. This makes the Tooth Fairy Project a bit 
of folly from the very start.  As for Sr-89, there is no analytical reason 
why Sr-89 could not be detected in teeth and it probably could be detected if 
the premise of the Tooth Fairy Project is true. But of course there is every 
reason to think that their hypothesis is false.
