New traces of radioactive strontium have been detected in the Japanese Yokohama. The city is located 250 kilometers from the nuclear power plant emergency, "Fukushima-1".

The following substances were found near two sewage drains near the same house, where a few days ago, were also found particles of strontium. This is the first detection of strontium outside the 100-kilometer zone around the plant "Fukushima-1".

Strontium, which local authorities discovered today, has a concentration of 129 becquerels per kilogram, which is a high enough concentration of the radioactive substance.

Radioactive strontium or, as it is called, strontium-90 — a radioactive nuclide chemical element strontium. In the environment of strontium-90 falls mainly in nuclear explosions and the release of radioactive particles from nuclear power plants, according to ITAR-TASS.
