others have been skeptical that it was a completely successful test of a true hydrogen bomb as north korea claimed. determining whether it is a two-stage thermonuclear bomb or a fusion-boosted fission weapon may not be possible without radionucleide emission data. the yield estimates of less than 300 kt would be lower than any other nation's first test of a fusion-primary thermonuclear device, which would typically be in the 1000 kt range, while boosted fission weapons and variable-yield nuclear devices can be as low as hundreds of tons, but are not considered true hydrogen bombs; meanwhile the largest pure-fission bomb tested was ivy king at 500 kt. an october 2 "scientific american" article said the test was "estimated to have been a 160-kiloton detonation — far below an h-bomb's capabilities." martin navias of the centre for defence studies at king's college london noted that the breakthroughs needed to get from a fission to a fusion device would have to be done by the north koreans on their own – china, russia, pakistan, and iran would not or could not help.
