Japanese think tank publishes radiation data from CTBTO station in Takasaki

The Centre for the Promotion of Disarmament and Non-Proliferation (CPDNP) of the think tank Japan Institute of International Affairs (JIIA), has published a report on the findings of CTBTO’s radionuclide station in Takasaki, Japan (RN 38).

The report includes a chart with measurement results for 11 different radioisotopes covering the period 22 March – 26 July 2011. The Takasaki station also has the capability to detect noble gases. The report includes xenon measurements for the period 12 March – 29 March 2011.

The CPDNP, though officially not a part of the government, has been assigned with oversight role of Japan’s technical involvement in the CTBT verification regime. As such, CPDNP supervises the construction and operation of CTBTO monitoring stations in Japan, supports human resource development for Japan’s two National Data Centres and engages in related research activities.

CTBTO data contributed to rapid tsunami warning alerts in the wake of the devastating tsunami in  Japan on March 11. In the following days, as events of the nuclear crisis in Fukushima were unfolding and the international community became increasingly concerned about the dispersal of radiation in the atmosphere, CTBTO contributed information from its radionuclide stations, which picked up traces of radionuclides and noble gases around the world, as well as radiation dispersal modeling forecasts to 120 Member States and over 1,200 scientific and academic institutions.
