  • Cesium chloride: preventive medicine for radioactive

    Cesium is produced in high yield fission of uranium and plutonium Radioactive cesium needles are a radiation hazard for radiotherapists In this age of nuclear reactors, ie Chernobyl, radioactive cesium exposure may be a growing problem Furthermore, there are numerous therapeutic potentials forCesium chloride appears to be relatively nontoxic and could be distributed and combined with salt (it has a tolerable salty taste) in the event of widespread radioactive cesium exposure This hypothesis should be verifiable experimentally and may be particularly important for high risk temporary employees of nuclear reactorsCesium chloride: Preventive medicine for radioactiveCaesium chloride with nonradioactive caesium133 occurs naturally, as a trace constituent in some minerals and in mineral water (which is where caesium was discovered) It is most concentrated in a mineral called pollucite, also containing aluminium and silicon among other constituents, where caesium makes up around 20% of the wholeCaesium chloride | Magnificent molecules | RSC Education

  • Cesium137 | Cs PubChem

    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 radioactiveCesium137 will react with chlorine to form cesium chloride However it is highly radioactive so must be handled carefully, because of this it is often used to treat cancer patients and sterilizeIs cesium radioactive? AnswersGoiânia´s legacy of a handful of cesium chloride is 3,000 cubic metres of contaminated waste It is now buried in a near surface repository on the outskirts of the city, where it must be isolated for the next 300 years Despite improvements, worldwide radioactiveGoiânia´s Legacy Two Decades On | IAEA

  • Cesium 137 and its Gamma Radiation in Teleradiotherapy

    In the USA, radioactive cesium is produced at Oak Ridge as dry cesium chloride powder This powder is then pressed to form compact pellets with a density of about 33 g/cma, containing 22 curies of CS'~' per gram of solid The pellets are made in various diameters and doubly enclosed in welded stain less steel capsulesThe knowledge about cesium metabolism and toxicity is sparse Oral intake of cesium chloride has been widely promoted on the basis of the hypothesis referred to as “high pH cancer therapy”, a complimentary alternative medicine method for cancer treatment However, no properly confirmed tumor regression was reported so far in all probability because of neither theoretical nor experimentalClinical Effects of Cesium Intake | SpringerLinkCesium chloride appears to be relatively nontoxic and could be distributed and combined with salt (it has a tolerable salty taste) in the event of widespread radioactive cesium exposure This hypothesis should be verifiable experimentally and may be particularly important for high risk temporary employees of nuclear reactorsCesium chloride: Preventive medicine for radioactive

  • American Cancer Society on Cesium Chloride | Kill Cancer

    Subject: Cesium ChlorideOther common name(s): High pH TherapyScientific/medical name(s): CsCl Overview Radioactive cesium (cesium137) is used in certain types of radiation therapy for cancer patients However, there is no scientific evidence that nonradioactive cesium chloride supplements have any effect on tumors, and there have been some side effects reportedFor most applications, radioactive cesium chloride can be replaced by lowerhazard alternatives that will not change the performance of the medical and research equipment, the committee found Such options include using less hazardous forms of radioactive cesium, radioactive cobalt, and Xray generatorsGovernment Should Spur Replacement of RadioactiveCesium chloride can undergo a phase change as a result of the heat produced by radioactive decay This phase change occurs at about 450°C (840°F) with pure cesium chloride, but can occur between 300 and 500°C (570 and 930°F) in the encapsulated cesium chloride, depending on the impurities present (DOE 1990)Cesium and Strontium Capsules NWTRB

  • An isotope dilutionprecipitation process for removing

    A novel isotope dilutionprecipitation method has been developed to remove cesium137 from radioactive wastewater The process involves adding stable cesium chloride to wastewater in order to raise the total cesium concentration, which then allows both the stable and radioactive cesium ions to be precipitated together using sodium tetraphenylborateDoctors use radioactive cesium chloride salt, which contains the isotope cesium137, to irradiate blood before it is given to patients in blood transfusions The radiation is aimed at preventing transfusion associated graftversushost disease (TAGVHD), a rare but nearly always fatal complication to blood transfusions, in which transfused white blood cells attack the recipient’s tissue [1]Dealing with the DoubleEdged Sword of Cesium Bloodanticipates phasing out cesium chloride devices over the next decade France plans to phase out cesium chloride blood irradiation by 2016 and the Czech Republic within five years, while Denmark prohibits such irradiators already Sweden and Finland recommend to licensees that they use xrays rather than cesium chloride devicesSources and Materials Nonproliferation
