What's the Current Radiation Threat to Japan's Food and Water? 2011-03-23T22:44:33Z Elevated levels of the more dangerous cesium-137 were also found at Hitachinaka, but the government called those levels “very weak.” The Japanese Nuclear Power Crisis Deepens 2011-03-24T15:20:46Z He said iodine - linked to cancer if found in high doses - and cesium were both "volatile substances" which escape relatively easily when there are nuclear accidents. Japan iodine release lower than Chernobyl: expert 2011-03-23T15:28:02Z Five kinds of radioactive materials released by damaged fuel rods were detected in the adjacent sea, including iodine-131, cesium-134 and cobalt, according to Tepco. Tokyo Gives Water Warning as Japan Bids to Calm Radiation Fears 2011-03-23T08:50:04Z Five kinds of radioactive materials released by damaged fuel rods were detected in the sea, including iodine-131, cesium-134 and cobalt, according to Tokyo Electric. Nuclear Cleanup Faces Key Power Test as Quakes Rattle Fukushima 2011-03-23T01:18:02Z Edano said there were no health risks, even at the highest cesium readings. Japan: no-man's zone large enough despite radiation 2011-03-22T16:38:34Z Readings in seawater for cesium-134 were 25 times normal and those for cesium-137 were 17 times higher, it said. Radiation Leaks Into Sea From Exposed Japanese Nuclear Fuel Rods 2011-03-22T04:43:01Z Tokyo's tap water, where iodine turned up Friday, now has cesium. Japan's disaster toll rises with 18,000 deaths 2011-03-21T03:57:00Z Posted to 80% Of Waste from California Walmarts Diverted From Landfills “radioactive cesium, strontium and iodine are bad bad stuff that you don't want to inhale. they are also beta emitters,...” Options For Replacing Japan's Busted Nukes 2011-03-21T04:29:19Z At the checkpoint leading to the exclusion zone, there is a small statue of the Virgin Mary and a placard listing the amounts of cesium and strontium found in mushrooms, fish and wild game. Lessons From Chernobyl for Japan 2011-03-19T22:28:46Z The government said Friday that it would test meat for cesium, plutonium and uranium, but gave no timetable. Food Contamination Fears Could Harm Japanese Brands 2011-03-19T19:52:28Z These rays are emitted during the decay of certain versions of uranium, iodine, cesium and other elements. What You Need to Know about the Japan Nuclear Crisis 2011-03-18T22:15:06.020Z Iodine breaks down quickly, after eight days, minimizing its harmfulness, unlike other radioactive isotopes such as cesium-137 or uranium-238, which remain in the environment for decades or longer. Japan's disaster toll rises with 18,000 deaths 2011-03-21T03:57:00Z Radioactive barium, cesium, iodine and tellurium have been detected in the plume, the Austrian agency said. Atomic Plume Poses No Serious U.S. Threat 2011-03-17T21:40:43Z Following is a list of the main WHO recommendations: * The main radionuclides released in a nuclear power plant accident are radioactive cesium and radioactive iodine. WHO issues guidelines on radiation exposure 2011-03-17T20:48:18Z The plume is heading over the Pacific Ocean and contains radioactive barium and cesium emitted from the damaged Fukushima Dai-Ichi power plant, Austria’s Meteorological and Geophysics Center said on its website. FAA, Airlines Track Japan Radiation Plume Over Pacific Ocean 2011-03-17T20:34:01Z For instance, cesium-137 mimics potassium and is absorbed by muscles, while strontium-90 mimics calcium and is taken up by bones. Quake Question #8: What Impact Will the Radiation Have on Marine Life? 2011-03-16T22:40:43Z “If the water leaks or boils away, then the fuel is exposed,” then after burning, the uranium corrodes and releases cesium, contaminating the area, he said. Japan Fights to Prevent Nuclear Meltdown 2011-03-16T17:44:02Z For example, cesium-137 has a half-life of 30 years, meaning it will take three decades for it to lose half its radiation punch. Workers Battle Fukushima Nuclear Crisis at Personal Risk 2011-03-16T17:45:02.440Z But radioactive forms of the particulate cesium persist much longer, and in the regions affected by Chernobyl, they are still the main threats to human health and will be for decades. Precautions Should Limit Health Problems From Nuclear Plant?s Radiation 2011-03-16T02:54:38Z But cesium, plutonium and strontium would still be present in large quantities. Wind and Rain Steer Radiation?s Reach 2011-03-16T01:46:43Z But one unmistakable symptom of core damage would be a plume of radio-isotopes such as cesium-137, iodine-131 and strontium-90 escaping in the steam being vented from the plant. Radiation Effects Vary 2011-03-16T00:17:09Z The radioactive particles probably contain materials linked to cancer in high doses, including cesium and iodine. Experts: Nuclear fallout from Japanese plant poses little threat to United States _ for now 2011-03-15T23:49:34Z Type of radiation: The type of radiation of concern in the current situation is ionizing radiation, which is produced by spontaneously decaying heavy atoms, such as iodine-131 and cesium-137. How Radiation Threatens Health 2011-03-15T23:45:00.243Z Nonetheless, as far away as Tokyo, 240 kilometers to the south, the city government says small amounts of the radioactive iodine and cesium have been detected in the air. Does Potassium Iodide Protect People from Radiation Leaks? 2011-03-15T21:45:07.540Z But the area around the plant would become a no-man’s land, contaminated with radioactive elements like cesium, plutonium and iodine. Wind and Rain Steer Radiation?s Reach 2011-03-16T01:46:43Z Iodine-131 and cesium-137 were both very broadly transported hundreds of kilometers, while strontium-90 remained in dust just 30 kilometers from the power plant and plutonium traveled only four kilometers or so. The worst nuclear plant accident in history: Live from Chernobyl 2011-03-15T12:15:07.357Z It is cesium 137 that still contaminates much land in Ukraine around the Chernobyl reactor, which suffered a meltdown in 1986. In Stricken Fuel-Cooling Pools, a Danger for the Longer Term 2011-03-15T02:10:09Z Zirconium fires could lead to massive amounts of radioactive cesium being emitted from the spent fuel and spewed into the atmosphere as part of the smoke. Three Questions About Japan's Nuclear Plants 2011-03-14T23:42:35Z Still, the two main elements of concern from a radiation leak would be radioactive iodine and cesium, which has a half-life of 30 years, so it stays around for a little while. Does Potassium Iodide Protect People from Radiation Leaks? 2011-03-15T21:45:07.540Z Trace amounts of radioactive elements cesium-137 and iodine-131 were also detected outside the plant. Nuclear crisis deepens as third reactor loses cooling capacity 2011-03-14T18:00:01Z The rusting also results in the production of explosive hydrogen; the cracking allows the most volatile radioactive elements in the fuel, like iodine and cesium, to escape. A Look at the Mechanics of a Partial Meltdown 2011-03-14T05:14:35Z The big worries on the reported releases of radioactive material in Japan center on radioactive iodine and cesium. Danger Posed by Radioactivity in Japan Hard to Assess 2011-03-13T05:05:30Z Radioactive cesium, a product of atomic fission, was detected near the site yesterday, indicating a meltdown may have begun, Nuclear and Industrial Safety Agency spokesman Yuji Kakizaki said yesterday. Japan Tries to Cool Reactor, Avert ‘Three Mile Island’ 2011-03-12T22:21:01Z More troubling, cesium and strontium linger not just in the body, but in the environment. Assessing the Radiation Risk 2011-03-12T21:47:02Z "If damage expands, cesium or other radioactive materials may be released not only inside the containment dome but also into the environment," he said. Japan Reactor Faces Meltdown Threat 2011-03-12T07:15:30Z A second of time, for instance, is now defined in terms of an electron transition of the cesium atom. Researchers Weigh Benefits Of A New Kilogram Standard 2011-01-24T18:15:00.250Z It is cesium-137 that still contaminates much of the land in Ukraine around the Chernobyl reactor. Danger Posed by Radioactivity in Japan Hard to Assess 2011-03-13T05:05:30Z The Laramie River Station, completed in the early 1980s, does not split atoms, but it does use cesium, as many coal plants do. And You Thought Radiation Was a Problem for Nuclear Plants? 2010-08-30T21:40:00Z Strontium and cesium are the next up the danger scale. Assessing the Radiation Risk 2011-03-12T21:47:02Z Radioactive isotopes include strontium 90 and cesium 137.
