“…Charcoal has been widely used as an adsorbent of radionuclides in various industries, including food processing, and is reported to adsorb iodine, radon, pertechnetate, thallium, and uranium (Klasson and Taylor, 2006;Rivera-Utrilla et al, 1984;Caccin et al, 2013); limited information about adsorption of radioactive cesium by charcoal exists. In general, these studies show that soluble cesium (radioactive or not) is not effectively removed by charcoal (Caccin et al, 2013;Kosaka et al, 2012;Rivera-Utrilla et al, 1984;Verzil et al, 1992;Liu et al, 2014).…”
