Setagaya Radiation likely came from radium in bottles beneath floor of empty house

Setagaya Ward officials said Thursday night that an extremely high level of radiation has been detected in bottles kept in a box beneath the floorboards of an unoccupied house in Setagaya, and that this is most likely the source of radiation detected on a nearby street on Wednesday.Researchers found radiation levels of 3.35 microsieverts per hour in tree leaves at a height of one meter by the fence of the unoccupied house along the street in Tsurumaki — much higher than previously reported levels. Initially, officials thought that the radiation may have come from the crippled Fukushima Daiichi nuclear power plant which is 220 kilometers away.

Tokyo Plans Radiation Checks After High Reading in Setagaya

Tokyo’s Setagaya ward in the western part of the capital plans to run radiation tests in 258 locations following the discovery of radiation above safety levels that required partially blocking off a sidewalk.

Setagaya ward, which has a population of more than 840,000 people, plans to decontaminate the area after radiation levels as high as 2.707 microsieverts per hour were detected at the site in the Tsurumaki 5-chome area, according to a statement by the ward.

The 2.7 microsieverts an hour equates to a dose of 14.2 millisieverts per year, or more than 14 times the internationally recommended level for the general public, according to a Science Ministry formula.
