Second tainted bottle found in Setagaya

A bottle believed to have contained radium was found beneath the ground near a supermarket in Setagaya Ward, Tokyo, on Tuesday in the second such discovery since high levels of radiation were detected in the area last month, officials said.

A Setagaya official said the substance inside the bottle was highly likely to be radium-226. The bottle was found buried in soil at a spot where the radiation reading reached 170 microsieverts per hour.

Radium-226 has been used for medical procedures.

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.
