Beijing: Waters of the western Pacific, close to Japan’s tsunami-hit nuclear plant, are “clearly affected” by the radioactive materials leaked from the crippled Fukushima facility, tests by China’s state agency have found.
China’s State Oceanic Administration, which conducted the studies in the area, said today that waters in the western Pacific region, close to the east and southeast of the Fukushima nuclear power plant are found to have radioactive material in excess of normal quantities.
Initial tests of samples collected from these areas show that radioactive Cesium-137 and -134, as well as Strontium-90 can be found in all water samples, it said in a statement.
Under normal conditions, Cesium-134 cannot be detected in sea waters, but the maximum amounts of Cesium-137 and Strontium-90 detected in the samples are 300 times and 10 times, respectively, of the amounts of natural background radiation in China’s territorial waters, it said.
However, the amount of radioactive materials in air samples tested as normal.
The administration has sent professional personnel to these waters to monitor the impact of the crisis at the Fukushima Daiichi nuclear power plant, as well as to China’s territorial waters.
The 18-day voyage, which ended on July 4, monitored waters of 25.2 square kilometers stretch, and the monitoring team collected air, water and biological samples from the spot areas, the statement said.
The administration will continue to publish results of further testing and evaluations of the samples, the statement said.
The Fukushima Daiichi Nuclear Power Plant in Japan was crippled by a 9.0-magnitude earthquake and ensuing tsunami on March 11. Zeenews
