It is still not confirmed that a nuclear test was performed. I am reading many analysts who believe this was not a nuclear test.

I have read this as well.

So far, some particulars are :

"It could be a fake," Orcutt said of the North Korean explosion, "but it’s probably not."

North Korea’s provocative weapons test Monday was either an unusually small nuclear bomb, only partially successful, or possibly even a faked test done with conventional explosives, say seismologists studying the latest freely available seismic data from South Korea and China.

The North Korean test looks to have released the equivalent of between 0.5 and 2 kilotons of TNT, according to a U.S. government scientist who asked not to be identified. For comparison, the U.S. atomic bomb detonated over Hiroshima, Japan, in 1945 released the explosive equivalent of 13 kilotons of TNT.

The three most likely explanations for the low yield are 1) that it was a very small nuclear bomb, 2) that it was a larger bomb that only partially detonated or 3) that it was not a nuclear weapon at all, but a large amount of conventional explosives set off to imitate a small nuclear blast.

The only official word so far on that subject is from the North Korean government in Pyongyang, which has declared a successful nuclear test.

Something tells me tthat the North Koreans probably don't worry about such things as radiation sickness to their own people and enviromental damage and whatnot. But who knows, maybe they do...

Why would they worry about it, they control everything within the country, and could probably find some way to spin that into being the result of foreign interference.

If they did not care, their would be nobody to govern.
