【 摘 要 】

In this paper, the performance of adsorbing and retarding 125I (substituted for 129I) for mixed minerals as buffer, backfill material was investigated. The distribution coefficient Kds by batch sorption experiments were determined for four kinds of minerals and one kind of bentonite under atmosphere. Sorption and desorption of radioiodine on several minerals were studied under low oxygen ambience at first time in the domestic, and apparent diffusion coefficient Da of 125I- was determined for mixed minerals under atmosphere.
