North Korea Air Sample Shows Radiation
Apocalypse111 writes, "According to CNN.com, air samples taken over North Korea have not yet shown any radiation from the event on Monday that North Korea claims was a nuclear test. This is not definitive proof that the event was non-nuclear, as it may either have been so small and deep that it did not let any radioactive debris escape, or perhaps the North Koreans sealed the site." Furthering speculation over whether North Korea has actually exploded a nuclear device, vk38 writes to point out a (free) article in today's Wall Street Journal claiming that the blast could have been
set off by exploding fertilizer (ammonium nitrate). The article points to the
Texas City disaster of 1947, in which 7,700 tons of ammonium nitrate exploded in the hold of a ship with the estimated power of 2 to 4 kilotons of TNT.
Update: 10/14 08:03 GMT by Z : The story at CNN has been updated: "A preliminary analysis of air samples from North Korea shows 'radioactive debris consistent with a North Korea nuclear test,' according to a statement from the office of the top U.S. intelligence official."

This is really the best confirmation data we have. DPRK says they set off a nuke. Even if a nuke had fizzled, it would've been bigger than the 550T explosion the seismometers felt. From here, "A geology professor at Yale, Jeffrey Park, emails to tell me that the updated Richter magnitude for the North Korea event is 3.5, which he calls "mighty small for a crude nuke." And that's true: it suggests a very small yield. But the odd thing is that it's actually harder to build a 1 kiloton weapon than a 5 or 10 kiloton weapon, and it's unlikely North Korea has the expertise to do this."
So, nobody's really sure what to believe right now, and eventually it'll just fall to consensus on the data we already have.
The best place to hear about the debate's over at ArmsControlWonk. New radionucliotide data, insider info from some well-placed anonymous sources, and insights into the scientific cultures within dictatorships paints an interesting picture.
