Chernobyl Radioactive Fallout on the Biosphere of Biwa Lake
Entry ID: BIWALAKECHERNOBYLCONTAMINATION

[ Update this Record ]

Summary
Abstract: 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. 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.
