通过评估渗透的氚化水和最初存在于水泥材料中的氢之间的相互作用，以估计暴露于氚化水蒸气的水泥材料中的氚库存。大约80%的渗透氚化水被发现含有自由液态水。氚化水被认为是通过氚和氢原子之间的交换反应与水泥材料相互作用的。氚与材料相互作用的浓度被认为与空气中的氚浓度成正比。因此，水泥材料中的氚存量取决于材料的孔隙率。
Interactions between penetrating tritiated water and hydrogen species originally present in cement materials were evaluated to estimate the tritium inventory in cement materials exposed to tritiated water vapor. Approximately 80% of the penetrated tritiated water was found to be contained in free liquid water. Tritiated water was considered to interact with cement materials by means of exchange reactions between tritium and hydrogen atoms. The concentration of tritium interacting with materials was considered to be proportional to the tritium concentration in air. The tritium inventory in cement materials was thus dependent on the porosity of the material.
