Cesium-137 har en halveringstid på 30 år och kommer därför att finnas kvar i naturen under en Radioaktivt cesium i övriga livsmedel: 300 becquerel per kg.

Det cesium-137 som spreds över norra Europa efter Tjernobylkatastrofen är källa till såväl β-strålning som γstrålning. Man får i genomsnitt vänta i 30 år innan en

Sedan Tjernobylolyckan 1986 har halterna av radioaktivt cesium i viltkött varit förhöjda i vissa delar av landet t ex i områden kring Gävle och Heby. I samband med olyckan hamnade radioaktivt cesium-137 i naturen och vattnet därför kan man än idag hitta cesium-137 i t ex vilt, fisk och svamp. Cesium-137 is produced in nuclear fission and occurs in atmospheric debris from weapons tests and accidents. It is a very important component of radioactive fallout; and because of its moderately long half-life and high solubility, it is a major source of long-lived external gamma radiation from fallout.

Cesium-137 is water-soluble and extremely toxic in minute amounts. The radioactivity of Cesium-137 can damage cells and cause cancer 10, 20 or 30 years from the time of ingestion, inhalation or absorption, provided sufficient material enters the body. Cesium-137 or Caesium-137, represented as Cs-137 or 137Cs, is a radioactive isotope of cesium.

Cesium Element Facts The chemical element cesium is classed as an alkali metal. It was discovered in 1860 by Robert Bunsen and Gustav Kirchhoff. Data Zone

This particular isotope of caesium is both a beta and gamma emitter. It is produced in some abundance by fission reactions.

Livsmedelsverket lägger ner kontrollprogrammet för cesium-137 i renkött nästa år.

Although Cs-137 decays via beta – decay, it is the daughter nuclide’s subsequent gamma emissions that are responsible for most dose when used as an enclosed source in cancer treatment. This article gives a comprehensive description of Cesium-137, Caesium-137 or radiocaesium which 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 Caesium 137 A legacy of atmospheric nuclear bomb tests and accidents. Caesium 137 is a radioactive element with a relatively long half-life of 30.15 years. This particular isotope of caesium is both a beta and gamma emitter.

It has a half-life of 30.23 years, and decays by The radioactive isotope caesium-137 has a half-life of about 30 years and is used in medical applications, industrial gauges, and hydrology. Nonradioactive Caesium is at the bottom of the first group, and is very reactive. If you throw a little caesium into Caesium has two radioactive isotopes – Cs-134 and Cs-137. Prior to the first nuclear bomb detonation in July of 1945, isotopes such as strontium-90 and cesium-137 simply did not exist in nature.

Caesium-137 has been found to effect children in the same way as adults. Similar to adults, stable caesium, Cs-133, is not likely to have an affect on children's health; however, just like with any radionuclide, exposure to large amounts of radioactive caesium-137 will induce large amounts of gamma radiation that will damage vital cells and could culminate in random DNA indels and the manifestation …
