Cesium-133 is naturally occuring and is stable(2). There are 52 isotopes and isomers of cesium with masses ranging from 112-148(1). How many isotopes of cesium are there in the world? This radionuclide has a relatively long half-life, 30 years, and decays by emitting beta particles. Why does Cesium Cs 137 have a long half life?Ĭesium 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. Where did the radioactive isotope caesium 137 come from?Ĭaesium-137, along with other radioactive isotopes caesium-134, iodine-131, xenon-133, and strontium-90, were released into the environment during nearly all nuclear weapon tests and some nuclear accidents, most notably the Chernobyl disaster and the Fukushima Daiichi disaster. How many protons and electrons does Cesium 137 have?Ĭesium-137 has 78 neutrons, 55 protons and 55 electrons(same as atomic number) How many neutrons protons and electrons does cesium have? Cesium has about 14 protons and 12 protons your-welcome answered by BIG TOM DELRAY BEACH BRICK SQUAD MEMBER The remainder directly populates the ground state of barium-137, which is stable. About 94.6% decays by beta emission to a metastable nuclear isomer of barium: barium-137m (137mBa, Ba-137m). How long does it take for cesium-137 to decay?Ĭaesium-137 has a half-life of about 30.17 years. Exposure to Cs-137 can increase the risk for cancer because of exposure to high-energy gamma radiation. Is Cesium-137 a beta emitter? What does cesium-137 do to the human body?Įxternal exposure to large amounts of Cs-137 can cause burns, acute radiation sickness, and even death. Cesium-137 emits beta particles as it decays to the barium isotope, Ba-137m (half life = 2.6 minutes). Cesium-137 is significant because of its prevalence, relatively long half life (30 years), and its potential effects on human health. Is cesium-137 a beta emitter?Ĭesium-137 decays in the environment by emitting beta particles. : a radioactive isotope of cesium that has the mass number 137 and a half-life of about 12 months and that is a by-product of nuclear fission. What is the formula for cesium-137?Ĭesium-137 Caesium-137 Cesium Cs-137 UNII-4T2E65IAR7 4T2E65IAR7 More… Cesium-137 is one of its most common radioactive forms. It can be non-radioactive or radioactive. With a mass number of 137, you subtracted the 55 protons and correctly calculated that there are 82 neutrons.Ĭesium (Cs) is a metal with atomic number 55, group 1, and period 6. Correct! From the atomic symbols you interpreted that this isotope of cesium has 55 protons and an equal number of electrons. How many protons electrons and neutrons are there in cesium-137? 6 Why does Cesium Cs 137 have a long half life?.5 How many protons and electrons does Cesium 137 have?.4 What does cesium-137 do to the human body?.1 How many protons electrons and neutrons are there in cesium-137?.
