Cation exchange resins (calcium polystyrene sulfonate, Ca-resin and sodium polystyrene sulfonate, Na-resin) have been used as agents to improve hyperkerlemia. For removing <sup>137</sup>Cs from the human body, the adsorption ability of the resin for <sup>137</sup>Cs was examined and evaluated. Resin (0.03 g) and <sup>137</sup>Cs (ca.1 kBq) were introduced into 3 mL of water, the Japanese Pharmacopoeia 1st fluid for a dissolution test (pH 1.2) and 2nd fluid (pH 6.8), respectively, and shaken. After 1-3 hours, the <sup>137</sup>Cs adsorption (%) of Na-resin was 99% in water, 60% in a pH 1.2 fluid and, 66% in a pH 6.8 fluid. By adding potassium, the <sup>137</sup>Cs adsorption (%) of Ca-resin was reduced. However, the <sup>137</sup>Cs adsorption (%) of Na-resin was almost unchanged. These results show that both resins have adsorption ability for <sup>137</sup>Cs in the stomach and the intestines. Therefore, the proposed method will be an effective means in the case of a radiological emergency due to <sup>137</sup>Cs.
