The German Federal office for radiation protection claims to have found the explanation for the recent increase in the content of the radioactive isotope ruthenium-106 in the air of several countries in Central and Western Europe. According to the Agency, the source of the increase in radiation level could be in the southern Urals.
Last week the German Federal office for radiation protection reported a small increased radioactivity in Europe. In particular, the radioactive ruthenium-106 in safe for life and health concentrations were detected in air samples in Germany, Italy, Austria, Switzerland and France.
The experts say that the reason for the surge of radioactivity are still unclear, but “high probability, its source is in the southern Urals”. On the basis of which to make such conclusions, the report did not specify. While in Berlin, eliminates the accident at the nuclear power plant as the cause of increasing the content of ruthenium-106, as other radiological isotopes was not detected in air samples.
Ruthenium-106 is used in medicine and is also sometimes used as a source of energy for some satellites. Its half-life is 373,59 of the day is much longer than the other unstable isotopes of the main elements, for which this period is calculated in seconds or even fractions of a second.
