Sorption and desorption experiments using stable cesium: considerations for radiocesium retention by fresh plant residues in Fukushima forest soils
Abstract
<jats:title>Abstract</jats:title><jats:p>We conducted sorption experiments with stable cesium (<jats:sup>133</jats:sup>Cs) solution in different organic matter samples, aiming to understand the sorption of radiocesium (<jats:sup>134</jats:sup>Cs and <jats:sup>137</jats:sup>Cs) in the initial throughfall by fresh plant residues (e.g., needles, wood, and bark from Japanese cedar trees) in the Oi horizon in forests in Fukushima. Among the organic matter samples, bark and wattle tannin sorbed relatively large amounts of Cs, whereas wood and cellulose powder sorbed small amounts. In contrast, samples containing clay minerals showed much higher Cs sorption. We also conducted desorption experiments, and suggested that Cs on the organic matter samples were relatively mobile.</jats:p>
