| 内容記述 | Medaka, as an excellent experimental animal model, is used to identify and predict human health effects in varied research fields including radiobiology. So far a lot of data for the radiation research on medaka have been accumulated such as lethal dose, radiation recovery, hereditary effects, radiation protection, radiological defense, etc. It is known that medaka is about 5 times more resistant to radiation compared with human. The aim of our project is to investigate whether the radiation from Fukushima nuclear power plant disaster could induce any effects in environmental field. We searched around Fukushima Daiichi nuclear power plant (FDNPP) for wild types of medaka, and found 2 points where the wild medaka are constantly available. The point Nakata is around 4 km far from FDNPP, and ambient dose rate is 0.9 μSv/h, and the point Saruta is around 7.5 km far from FDNPP and ambient dose rate is 22 μSv/h. We surveyed the radio activity of the wild medaka and surrounding soil (Nakata: medaka 720Bq/kg, soil 1,600Bq/kg Saruta: medaka 4,430Bq/kg, soil 115,000Bq/kg in November 2013). The radiation effects on the medaka were evaluated using the micronucleus assay. No significant difference for the frequency of micronucleated cells was observed among medaka from Nakata, Saruta and our cultivated medaka that were used as the control. | |||||
