April Flowers for redOrbit.com - Your Universe Online Radioactive cesium isotopes from Japan's Fukushima nuclear power plant — severely damaged in the 2011 tsunami and earthquake — have made their way to the waters just off the coast of Canada. The announcement was made at the annual American Geophysical Union's Ocean Sciences Meeting in Honolulu this week, but the scientists noted that the concentrations of the two isotopes were still well below safe drinking levels, reports Brooks...

Redefining Time With Innovative Optical Lattice Clock
2013-07-10 12:56:58

Michael Harper for redOrbit.com - Your Universe Online Atomic clocks are the standard in time, hailed as the most accurate and often used to keep other clocks on time. Now, a new kind of clock aims not only to replace atomic clocks as the most accurate, but to redefine the second as a measurement of time as well. The new device, called an optical lattice clock (OLC) is, theoretically, three times more accurate than current atomic clocks. In computer models, these clocks lost only one...

Tsukuba, Japan, Feb 7, 2013 - (ACN Newswire) - Radioactive leaks, such as at the Fukushima Daiichi nuclear plant in Japan, contaminate the local environment. Contamination of soil and water by the radioactive form of caesium is a major problem, since it persists for a long time; levels of radioactivity reduce by half only every 30 years. Effective detection and removal of radiocaesium would accelerate recovery of the environment.Current detection methods can only localise contamination on a...

Better Accuracy For Optical Strontium Clock

Alpha Galileo Foundation PTB measures the influence of the ambient temperature on strontium atoms for the first time — measurement uncertainty reduced by one order of magnitude An optical clock with neutral strontium atoms is considered one of the top candidates for the definition of a "new" second. The probabilities have increased considerably, since its frequency will now be determined more accurately (probably by an order of magnitude). Scientists of the Physikalisch-Technische...

Seafood Being Sold Again In Japan
2012-06-26 14:08:22

Brett Smith for redOrbit.com The first seafood caught off the Japanese coast of Fukushima since last year´s nuclear meltdown went on sale Monday – a sign the million-dollar fishing economy is on the mend. The first day´s offerings were limited to the only commercial sea creatures that have consistently tested negative for radioactive cesium: octopus and whelk, a type of marine snail. Japanese fishmongers are hoping sea bass and flounder soon follow, but are aware that...

A Sandia National Laboratories technology has been used to remove radioactive material from more than 43 million gallons of contaminated wastewater at Japan's damaged Fukushima Daiichi nuclear power plant. Sandia researchers had worked around the clock following the March 2011 disaster to show the technology worked in seawater, which was pumped in to cool the plant's towers. "It's the kind of thing that sends a chill," said Mark Rigali, manager of the geochemistry group at Sandia. "We've...

The March 11, 2011, earthquake, tsunami, and subsequent radioactivity releases from the Fukushima Dai-ichi nuclear power plants resulted in the largest accidental release of radiation to the ocean in history. In a special session on Tuesday, Feb. 21, during the 2012 Ocean Sciences Meeting in Salt Lake City, researchers will present early results from several field and modeling studies examining the fate of more than a dozen radioactive isotopes in the air, water, and organisms impacted by...

High Radioactivity Levels In Tokyo Causing Concern
2011-10-16 04:50:05

Multiple radioactive "hot spots" in and around Tokyo -- some 125 miles from a nuclear facility damaged by a March earthquake -- have been detected by citizens using radiation-detection gear, various media outlets reported late last week. According to Chico Harlan of the Washington Post, residents reported on Thursday that they had discovered two areas with elevated radiation levels, some of which were higher than those within the 12-mile evacuation zone. One of those two readings could...

Cesium (or Caesium) is a chemical element with the symbol Cs and atomic number 55. Caesium is a soft alkali metal that is silvery-gold. It melts and liquefies at 83 degrees Fahrenheit and is one of only five metals that are liquid close to room temperature. Caesium is a metal that is most widely known for its use in atomic clocks. Cesium comes from the Latin word caesius meaning "˜bluish-gray'. It was discovered in 1860 by Robert Bunsen and Gustav Kirchhoff in Durkheim, Germany in mineral...
