使用含有从辐照燃料中提取的裂变产物的溶液，观察了放射性核素（如137 Cs）进入干燥混凝土材料、干燥砂浆材料和环氧涂料数十天的渗透行为，以获得放射性核素渗透速率和深度的基本信息。几乎没有任何放射性核素能够渗透到环氧树脂涂料中。放射性核素溶液渗透到混凝土和砂浆材料中，深度为几毫米，持续了几十天。在混凝土和砂浆材料表面附近观察到的渗透行为类似于核素在水饱和混凝土、膨润土和水泥材料等介质中的扩散。
Penetration behavior of radionuclides such as 137Cs into dried concrete material, dried mortar material and epoxy paint for a few dozen days was observed using a solution containing fission products extracted from irradiated fuels to obtain fundamental information on the radionuclide penetration rate and depth. Hardly any radionuclides could penetrate into the epoxy paint. The radionuclide solution penetrated into concrete and mortar materials to a depth of a few millimeters for a few dozen days. The penetration behavior observed near the surface of concrete and mortar materials was similar to the diffusion of nuclides in media such as water-saturated concrete, bentonite and cement materials.
