Cesium 139

Hollywood - meh. They wouldn't recognize a scientific fact if it showed up at a Hollywood party with a pound of cocaine. I haven't seen the film, so I can't confirm that they said Cs-139, but if they did they would be wrong. But I am so cynical -. Detailed decay information for the isotope cesium-139 including decay chains and daughter products Cesium Cs 137 is a radioactive isotope of cesium with an atomic mass of 139 and potential application in radiotherapy. Cesium Cs 137 is prevalent due to its spontaneous production, which occurs as a result of nuclear fission of other radioactive materials, such as uranium and plutonium.This radionuclide has a relatively long half-life, 30 years, and decays by emitting beta particles

Is cesium-139 really as deadly and sought after by

  1. Caesium (55 Cs) has 40 known isotopes, making it, along with barium and mercury, one of the elements with the most isotopes. The atomic masses of these isotopes range from 112 to 151. Only one isotope, 133 Cs, is stable. The longest-lived radioisotopes are 135 Cs with a half-life of 2.3 million years, 137 Cs with a half-life of 30.1671 years and 134 Cs with a half-life of 2.0652 years

  3. Caesium-137 (137 55 Cs), or radiocaesium, is a radioactive isotope of caesium that is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons.Trace quantities also originate from natural fission of uranium-238.It is among the most problematic of the short-to-medium-lifetime fission products
  4. Cesium-137 of 137 Cs is een instabiele radioactieve isotoop van cesium, een alkalimetaal met een te groot neutronenoverschot.De isotoop komt van nature niet op Aarde voor. Cesium-137 ontstaat door kernsplijting van zwaardere elementen, zoals uranium en plutonium.Het is - naast jodium-131 en cesium-134 - vrijgekomen bij de kernramp van Fukushima.Ook tijdens de kernramp van Tsjernobyl is de.
  5. Cesium-137: A Deadly Hazard Colin Wessells March 20, 2012 Submitted as coursework for PH241, Stanford University, Winter 2012 Introduction. Among the many fission product nuclides, cesium 137 deserves attention because it possesses a unique combination of physical properties and historical notoriety
  6. Why is Caesium dangerous? Cesium-137 is an especially dangerous fission product because of its high yield during fission, moderate half-life, high-energy decay pathway, and chemical reactivity. Because of these properties, cesium-137 is a major contributor to the total radiation released during nuclear accidents
  7. External exposure to large amounts of Cs-137 can cause burns, acute radiation sickness, and even death. Exposure to Cs-137 can increase the risk for cancer because of exposure to high-energy gamma radiation. Internal exposure to Cs-137, through ingestion or inhalation, allows the radioactive material to be distributed in the soft tissues.

Effets sanitaires - Absorbé par l'homme, le césium se répartit dans les muscles. Sa période biologique est de 100 jours, laps de temps au bout duquel il est éliminé de l'organisme. Cette élimination relativement rapide réduit sa nocivité. Elle signifie qu'un noyau de césium-137 seulement sur 160 absorbés se désintègre dans le corps humain Dealing with the Double-Edged Sword of Cesium Blood Irradiation. Doctors use radioactive cesium chloride salt, which contains the isotope cesium-137, to irradiate blood before it is given to patients in blood transfusions. The radiation is aimed at preventing transfusion associated graft-versus-host disease (TA-GVHD), a rare but nearly always.

Who found cesium? Simply so, where is cesium found? Source: Cesium is found in the minerals pollucite and lepidolite. Commercially, most cesium is produced as a byproduct of the production of lithium metal. More than two-thirds of the world's reserves of Cesium - 110,000 tonnes - are found at Bernic Lake, Manitoba, Canada. One may also ask.
