Telltale gas confirms Korean nuclear test

Unusually high levels of a radioactive noble gas detected in northern Canada
are final confirmation that North Korea detonated a nuclear device
underground in October 2006, say UN researchers.

The result demonstrates that a UN system to monitor nuclear explosions
worldwide is up and running, and able to "sniff" such events from a great
distance. Atmospheric levels of an isotope of the noble gas xenon suggest
the test was relatively small and carried out underground.
