WebJan 30, 2024 · Caesium-137 is a radioactive metal with a half-life of 30.05 years – meaning in three decades it will have half of its original activity. It emits beta and gamma radiation. WebCs-137 is used in small amounts for calibration of radiation-detection equipment, such as Geiger-Mueller counters. In larger amounts, Cs-137 is used in medical radiation therapy …

WebEach atom of 134 Cs changes into either xenon 134 (134 Xe) or barium 134 (134 Ba), neither of which is radioactive, while each atom of 137 Cs decays to barium 137 (137 Ba), which is also not radioactive. As 134 Cs and 137 Cs decay, beta particles and gamma radiation are given off. The half-life is the time it takes for half of that cesium ... WebMay 2, 2013 · Cesium, of course, is a different story. The ocean and its denizens continue to bear traces of cesium-137 that date from the atmospheric weapons testing during the Cold War era of the 1960s.

WebJun 11, 2024 · Dolaskom na mjesto događaja inspektori za radiološku i nuklearnu sigurnost Ravnateljstva civilne zaštite utvrđuju kako je izvor ionizirajućeg zračenja Cezij-137 (CS-137) te kako je okolni prostor kontaminiran uslijed oštećenja spremnika radioaktivnog izvora. Cezij je kemijski element atomskog (rednog) broja 55 i atomske mase 132,90545. U periodnom sustavu elemenata predstavlja ga simbol Cs. To je meki, srebrno zlatni alkalijski metal, s talištem na 28 °C, što ga čini jednim od pet metala elemenata koji su tekući na sobnim temperaturama. Budući da je cezij alkalijski metal, njegova fizička i kemijska svojstva su slična rubidiju i kaliju. … WebProduct Summary.
