Ruth and others,

I read about two years ago somewhere about two Sr-90 incidents - Sr-90 used 
for lighthouses (or ice-breakers??) I think (the order of many 
petabecquerels). One was lost into the from a helicopter near Sakhalin 
(probably sea of Okhotsk - spelling?) in 1997 and the other was crushed 
under a bulldozer near the river of Yenisey. I have however lost the 
litterature sources. Can anyone in Radsafers land give some help?
