【 摘 要 】

The relative release rates of nitrate, cesium, strontium, and technetium have been measured from saltstone and soilcrete (salt-stone containing soil) under saturated conditions. These are the first measurement of radionuclide release rates from saltstone, and confirm the assumptions used earlier in mathematical modeling. Both saltstone and saltcrete have comparable leach rates for nitrate and pertechnetate anions. Cesium and strontium are more strongly held in both materials, but show differences between the two matrices. These data fully support the assumption that no species leaches more rapidly than nitrate.
