  1. In this paper, the performance of adsorbing and retarding 125i ( substituted for 129i ) for mixed materials 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, iodine sorption and desorption on several mianerals 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

    在大氣條件下用批式實驗法研究了放射性125i - 、 125io3 - (用i - 125代替i - 129 )在黃銅礦、方鉛礦、黃鐵礦、辰砂上的吸附和解吸行為,並且在國內首次研究了低氧條件下碘在幾種礦物上的吸附和解吸行為;在大氣條件下,用恆定源擴散法研究了125i -在方鉛礦與膨潤土組成的混合材料中的擴散行為。
