Chernobyl Radioactive Fallout on the Biosphere of Biwa Lake
Listed in NASA Earthdata CMR
Trends and temporal changes on the radioactive nuclides on Osaka region and in the ecosystem of Biwa Lake located in approximately center of Japan, which were caused by the Chernobyl nuclear accident occurred on April 26, 1986, have been observed.
Description
I-131, Cs-137, Cs-134 and so on were detected in the suspended dust in air and also in the surface layer water of Biwa Lake. The depth distribution of Cs-137 in the lake soils and as variation on time course of Cs-137 in the Biwa Lake water and organisms in the lake had been observed.
Thus the radioactive fallout was estimated as a representative value in Japan. We continued our investigation of influence on the organisms in the fresh water ecosystem caused by radioactive nuclides released from chernobyl nuclear reactor accident.
