Doubt has been cast over claim North Korean nuclear device was Hydrogen bomb.
North Korean media claimed that it had successfully tested a hydrogen bomb, which was speculated to have existed the month before the test was carried out. The United States Geological Service reported a 5.1 magnitude earthquake from the location, the China Earthquake Networks Centre reported the magnitude as 4.9.
A newsreader on North Korean state TV said: “The republic’s first hydrogen bomb test has been successfully performed at 10:00 am on January 6, 2016.”
A Hydrogen weapon is a much more powerful atomic weapon than fission weapons such as those dropped on Hiroshima. A Hydrogen bomb derives its energy through the fusion of atoms.
“The bang they should have gotten would have been 10 times greater than what they’re claiming. So Kim Jong-un is either lying, saying they did a hydrogen test when they didn’t, they just used a little bit more efficient fission weapon – or the hydrogen part of the test really didn’t work very well or the fission part didn’t work very well.”
The data “doesn’t support suggestions that the bomb was a hydrogen bomb”, Chinese military expert Du Wenlong told state broadcaster CCTV.
Last month, North Korean leader Kim Jong-un said the country had developed a hydrogen bomb, most however were sceptical.
North Korea declared in 2009 that it had developed a nuclear weapon, and the country reportedly possesses a small stockpile of relatively simple nuclear weapons, this is believed to have been the fourth test.
