英文 | The Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) was founded in 1996 in response to the adaption of the Treaty in 1996 by the United Nations General Assembly, which bans nuclear explosions on the Earth's surface, in the atmosphere, underwater and underground. The Treaty has a unique and comprehensive verification regime to make sure that no nuclear explosion goes undetected. The regime is supported by International Monitoring Systems (IMS) composed of the four state-of-art technologies; 1) Seismic, 2) Hydroacoustic, 3) Infrasound, and 4) Radionuclide, by the International Data Centre (IDC), and by the On-Site Inspections (OSI). IMS will, when complete, consists of 337 facilities worldwide to monitor the planet for signs of nuclear explosion. Around 90 % of the facilities are in operation and sending the data to the IDC in Vienna, Austria. The seismic stations detected the past six announced underground nuclear explosion test by DPRK and identified the location, depth, and their magnitudes. IMS radionuclide stations detected the trace amount of the noble gas in twice of them. Radionuclide station in Takasaki, Japan, detected the noble gas released from the site, 50 days after the announced test. The huge amount of data collected by the stations can be used for other purposes such as civil and scientific applications in addition to detecting nuclear explosions. They can provide Tsunami Warning centres with near real-time information about an underwater earthquake. During the Fukushima Daiichi Power Plant accident, in March 2011, the IMS network's radionuclide stations tracked the dispersion of radioactivity on a global scale. The data could also help better understand the oceans, volcanos, climate change, the movement of marine mammals, and many other issues. This session will provide the overview of CTBTO and its IMS, the scientific discussion on each technology, and its outcomes. | ||
