    Wednesday, Oct. 12, 2011 Yokohama finds high strontium-90 levels Kyodo YOKOHAMA — Radioactive strontium exceeding normal levels has been detected in sediment from atop an apartment building in Yokohama, some 250 km from the Fukushima No. 1 nuclear power plant, city officials said Wednesday. While the discovery of 195 becquerels of strontium-90 in the rooftop sediment fueled concerns that leaked radiation may have spread farther than the central government expected, the officials said the city is carefully examining where the isotope came from. If the substance is from the Fukushima plant, it will be the first time strontium at a...

    * Vermont Yankee could close by March 2012 * Entergy fighting for reactor survival Aug 2 (Reuters) - Vermont health regulators said on Tuesday they found a fish containing radioactive material in the Connecticut River near Entergy's (ETR.N) Vermont Yankee nuclear power plant which could be another setback for Entergy to keep it running. The state said it needs to do more testing to determine the source of the Strontium-90, which can cause bone cancer and leukemia. Vermont Governor Peter Shumlin wants the 620 megawatts reactor shut in March 2012 when its original operating license was to expire. "Today's troubling...

    Survey: strontium widespread in Fukushima Soil samples from around Fukushima Prefecture have revealed concentrations of radioactive strontium. Japan's science ministry conducted a survey for radioactive substances at 11 locations in 10 municipalities from late March to mid-May. It says strontium-90 was detected in all 11 locations. In Namie Town, the reading stood at 250 becquerels per kilogram of soil, while in Iitate Village the reading was 120 becquerels per kilogram. The readings in the other locations were between 2 and 18 becquerels. Strontium-90 is generated during the fission of uranium in fuel rods in reactors. With a comparatively long half-life...

    Organism's ability to distinguish strontium from calcium could help in dealing with nuclear waste. Common freshwater algae might hold a key to cleaning up after disasters such as Japan's Fukushima nuclear accident, scientists said yesterday at a meeting of the American Chemical Society in Anaheim, California. The algae, called Closterium moniliferum, are members of the desmid order, known to microbiologists for their distinctive shapes, said Minna Krejci, a materials scientist at Northwestern University in Evanston, Illinois. But the crescent-shaped C. moniliferum caught Krejci's eye because of its unusual ability to remove strontium from water, depositing it in crystals that form...

    Agency says radioactive materials recovered in home of man allegedly slain by his wife ...BELFAST, Maine — James G. Cummings, who police say was shot to death by his wife two months ago, allegedly had a cache of radioactive materials in his home suitable for building a “dirty bomb.” According to an FBI field intelligence report from the Washington Regional Threat and Analysis Center posted online by WikiLeaks, an organization that posts leaked documents, an investigation into the case revealed that radioactive materials were removed from Cummings’ home after his shooting death on Dec. 9 It says that four 1-gallon...
