Philippine Institute makes available measurements of local CTBTO radionuclide station

The Philippine Nuclear Research Institute (PNRI), a government run institute under the Department of Science and Technology of the Philippines (DOST), closely monitors the situation at the Fukushima Daiichi nuclear power plant and provides on its website regular updates on radiation dispersal in the region.

Among other data, DOST-PNRI makes available the measurements of CTBTO’s radionuclide station RN52. This particular station, which is located in the town of Tanay, east of Manila, operates integrated into CTBTO’s International Monitoring System since 20 December 2005, when it was certified. The Philippine Nuclear Research Institute is the national agency tasked with servicing the station.

Below see the latest updated version of the table provided by DOST-PNRI with the measurements originating from the CTBTO radionuclide station in the Philippines. The table shows the concentrations of Iodine-131, Cesium-134 and Cesium-137, measured in microbequerels per cubic meter of air, for the period of 23-30 March.

More information available at the PNRI official website, here.
