Abnormal radiation detected near Korean border


So what would cause elevated radiation levels? Anyone?

Abnormally high radiation levels were detected near the border between the two Koreas days after North Korea claimed to have mastered a complex technology key to manufacturing a hydrogen bomb, Seoul said Monday.

The Science Ministry said its investigation ruled out a nuclear test by North Korea, but failed to determine the source of the radiation. It said there was no evidence of an earthquake, which follows an atomic explosion.

Inquiring minds want to know.

  • One possible source AFAIK given this information could be work on a nuclear fission-based detonator for the putative H-bomb. That is, I understand one way to achieve the energy levels necessary to start a fusion reaction is to initiate it by detonating a very small, focused fission (nuclear) reaction around the contained hydrogen. I don't know much detail beyond that and I'm not going to look it up. 🙂
