North Korea Tests Not Just a Bomb but the Global Nuclear Monitoring System
North Korea’s apparent nuclear detonation on September 3 has drawn our attention to a remarkable international organisation that helps detect and identify nuclear tests.
For the Vienna-based Comprehensive Test Ban Treaty Organization (CTBTO), the latest North Korean explosion was easy to detect and locate. With a seismic magnitude of 6.1 and a blast yield of 160 kilotons (Hiroshima was around 15), the purported hydrogen bomb test mimicked a major earthquake. It was quickly sourced to North Korea’s nuclear test site.
Confirming that the event was definitely a nuclear test, as opposed to another type of explosion or an earthquake, is trickier.
For that we rely on detection of short-lived radioactive isotopes that may leak from the test site, notably the noble gas xenon. The CTBTO has not yet announced such a finding, although South Korean monitors have reportedly detected xenon-133.
Other potential sources of the gas must be eliminated before a definitive conclusion can be reached.
