![]() ![]() Internal exposure to Cs-137 through ingestion or inhalation allows the radioactive material to be distributed in the soft tissues, especially muscle tissue, which increases cancer risk. 2Cs(s) + 2HO(l) H(g) + 2Cs(aq) + 2OH(aq) The reaction is so explosive that it often shatters the container. Over time, groundwater became the main source for leaks. ![]() 7 Initially, as of June 2011, the biggest threat was the leakage of caesium from the nuclear reactors into the Pacific. ![]() Large amounts of Cs-137 are not found in the environment under normal circumstances.Įxposure to Cs-137 can increase the risk for cancer because of the presence of high-energy gamma radiation. Cesium reacts with cold water to form hydrogen gas and a solution of cesium ions and hydroxide ions. Discharge to groundwater by leakage Abukuma River was banned from fishing for 10 years for radioactivity reasons. Since cesium is mostly present as the Cs ion state in water, it is not removed by sand filtration, and coagulation with polyaluminum chloride (PACl), powdered. Exposure to such a large amount could come from the mishandling of a strong industrial source of Cs-137, a nuclear detonation or a major nuclear accident. Other industrial devices that measure the thickness of materials such as paper or sheets of metal.Įxternal exposure to large amounts of Cs-137 can cause burns, acute radiation sickness and even death.Industrial gauges that detect the flow of liquid through pipes.Medical radiation therapy devices for treating cancer. Cesium hydroxide is a very strong base that can rapidly etch the surface of glass.You may wish to use the slow motion videos Rubidium, water and indicator and Caesium in water, both featuring commentary, from ’The Periodic Table of Videos’ by The University of Nottingham. Cesium-137 is used in small amounts for calibration of radiation detection equipment, such as Geiger-Mueller counters. Video clips showing the addition of rubidium and caesium to water. ![]()
