Japan: Radioactive Strontium Found in Yokohama, 250 KM From Fukushima Plant
“YOKOHAMA (Kyodo) — Radioactive strontium exceeding normal quantities has been detected in sediment from atop an apartment building in Yokohama, some 250 kilometers from the damaged Fukushima Daiichi nuclear power plant, city officials said Wednesday.
While the discovery of 195 becquerels of strontium 90 in the rooftop sediment has fueled concerns that leaked radiation may have spread further than the government had expected, the officials said the city office is carefully examining where the material came from.
This is the first time strontium at a concentration of over 100 becquerels per kilogram has been found beyond 100 km from the Fukushima plant. The strontium 90 was detected in Yokohama, south of Tokyo, by a private agency that conducted the test upon the request of a resident.
Strontium 90, with a half-life of 29 years, has been detected at concentrations roughly between 10 to 20 becquerels at various places across Japan prior to the nuclear crisis triggered by the March 11 earthquake and tsunami…
If inhaled or ingested, strontium tends to accumulate in bones just like calcium. It is believed to cause bone cancer and leukemia.” Read more.
Gov’t unveils plan to expand decontamination project areas – “The government has unveiled plans to sharply expand a government-funded decontamination project to areas with annual radiation emissions of 1 millisievert or more, prompting mixed reactions from local government officials and residents. Under the plan, the Environment Ministry is to designate those areas with annual radiation exposure of 1 millisievert or more as ‘priority contamination inspection areas’ by the end of November.” Read more.
