Japans Ministry of environment said 91 bags of radioactive soil were washed into the river last month after a strong typhoon, haibeth, hit the country. These radioactive soils are the result of the Fukushima nuclear accident in 2011 and are dangerous.
According to reports, the bags were previously placed in temporary storage sites in and around Fukushima Prefecture. Of the 91 bags containing radioactive soil washed away, 90 came from Fukushima Prefecture and one from Toyoma Prefecture, officials from Japans environment ministry said. So far, at least 25 bags have been found empty, which means the contaminated soil has been washed into the river.
