This work, which will,Caesium - Wikipedia,Caesium (IUPAC spelling) (also spelled cesium in American English) is a chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-golden alkali metal with a melting point of 28.5 °C (83.3 °F), which makes it one of only five elemental metals that are liquid at or near room temperature. Caesium has physical and chemical properties similar to those of rubidium and potassium.Prussian blue decorated hydrogel particles for effective,,The prepared particles have magneticity for easy harvesting after ion absorption. The efficiency of removing cesium ions using the particles is investigated depending on the size of particle. As the surface area increases in the micron-sized particle, the particle can increase the efficiency of removing cesium.

A large amount of radioactive cesium (Cs) has been released into natural environment following the nuclear accident in Fukushima, Japan in 2011. Much effort has been directed at capturing Cs and remediation of the contaminated environment. However, conventional sorbents, such as Prussian blue and zeolites cannot be easily recovered once spread into an open environment.ATSDR - ToxFAQs™: Cesium,3/3/2011· The EPA has established a maximum contaminant level of 4 millirem per year for beta particles and photon radioactivity for man-made radionuclides (including radioactive cesium). The Nuclear Regulatory Commission (NRC) has set limits for radioactive cesium in workplace air of 4x10 -8 microcurie per milliliter (µCi/mL) for 134 Cs and 6x10 -8 µCi/mL for 137 Cs.,
