In Fukushima Prefecture, the straw was found to contain up to 97,000 becquerels of radioactive cesium
Nor do these total numbers account for the release of other isotopes from lingering plant discharges, including strontium-90, which, although present in quantities much lower than cesium
, is of concern: It accumulates in the bones offish that could be eaten.
mineral pollucite has been identified within the Pakeagama Lake pegmatite and is only the fourth pollucite occurrence noted in Ontario.
Chapter Three Manufacturing Technology of Cesium
Fish also excrete cesium
fairly efficiently, losing a few percent per day.
This suggests that the cesium
contamination is likely in seafloor sediment, according to Buesseler.
It basically says that these things [optical atomic clocks] are now capable of being better than cesium
[clocks]," says atomic clock specialist Patrick Gill of the National Physical Laboratory in Teddington, England.
9 km away from the plant, containing radioactive cesium
concentrations of 651 becquerels per kilogram, the team said.
Madigan and his team focused on the two cesium
isotopes because they don't decay quickly, unlike other radioisotopes released by the Fukushima disaster.
That particular isotope of cesium
, which has a half-life of about 30 years, is generated when atoms of uranium-235 and plutonium-239 undergo fission within bombs or nuclear reactors.
A small group of Bikinians sent back to Bikini in the early 1970s had to be evacuated in 1978 because their diet of coconuts resulted in an alarming buildup of cesium
in their bodies.
18 ( ANI ): A mountain trout caught in the Niida River in Fukushima Prefecture contained 11,400 becquerels of radioactive cesium
per kilogram, more than 110 times above the government limit for food products, a survey by the Environment Ministry showed.
