Chosun IlboRight after North Korea claimed a successful nuclear fusion test on May 12, the northernmost radiation detection station of the (South) Korea Institute of Nuclear Safety detected an eightfold increase in the radioactive substance xenon, it emerged Sunday.
Since nuclear fusion is the core process in hydrogen bombs, there is speculation that the North actually ran a small-scale nuclear test to develop the technology at the time.
On May 14, two days after the North's announcement, air analysis of KINS's radiation detection station in Geojin, Gangwon Province showed about eight times as much xenon as in ordinary times, a government official said. "Authorities concerned have concentrated on analyzing this," he added.

"There was no tremor -- which usually goes with nuclear explosions -- detected at the time," the official said. "Xenon may have come from a nuclear reactor elsewhere or due to a reason we have yet to fully rstand."

Nuclear fusion potentially promises clean and limitless energy but can also be employed to make hydrogen bombs.
The North's announcement last month did not link the alleged fusion breakthrough to its atomic weapons programme.
Pyongyang's official media reported on May 12 that the North's scientists, using their own technology, had conducted a nuclear fusion reaction.
