Radium, not Fukushima, Source of Western Tokyo Radiation Spike

Radioactive radium-226 was the source of a high radiation reading in Tokyo’s Setagaya district yesterday, officials said, ruling out the possibility it may have come from the crippled Fukushima nuclear reactors.

An investigation of a house near the contaminated area turned up two boxes of bottles containing radium-226, Takao Nakaya, head of the Science Ministry’s office of the radiation regulation, said by phone today.
