What Goes Around, Comes Back Around
From
Science News Online:
A sensitive instrument installed in the Canadian Arctic to monitor fallout from
modern nuclear tests has detected small amounts of radioactive cesium produced
by bomb tests decades ago. The material, which during the Cold War was spread
across northern latitudes by high-altitude winds, is still being redistributed
far and wide by forest fires...
One scientist notes,
The cesium-137 lofted during a forest fire is diffusely distributed. "This isn't
a health risk, but it's interesting."
