Tritium extraction from radioactively contaminated cement mortar samples was performed using heating and liquid scintillation counting methods. Tritiated water molecules (HTO) can be present in contaminated water along with water molecules (H₂O). Water is one of the primary constituents of cement mortar dough. Therefore, if tritium is present in cement mortar, the buildings and structures using this cement mortar would be contaminated by tritium. The radioactivity level of the materials in the environment exposed to tritium contamination should be determined for their disposal in accordance with the criteria of low-level radioactive waste disposal facility. For our experiments, the cement mortar samples were heated at different temperature conditions using a high-temperature combustion furnace, and the extracted tritium was collected into a 0.1 M nitric acid solution, which was then mixed with a liquid scintillator to be analyzed in a liquid scintillation counter (LSC). The tritium extraction rate from the cement mortar sample was calculated to be 90.91% and 98.54% corresponding to 9 h of heating at temperatures of 200 °C and 400 °C, respectively. The tritium extraction rate was close to 100% at 400 °C, although the bulk of cement mortar sample was contaminated by tritium.

使用加热和液体闪烁计数方法从放射性污染的水泥砂浆样品中提取氚。氚化水分子 (HTO) 可与水分子 (H ₂哦）。水是水泥砂浆面团的主要成分之一。因此，如果水泥砂浆中含有氚，使用这种水泥砂浆的建筑物和构筑物就会受到氚的污染。暴露于氚污染环境中的物质的放射性水平应按照低放废物处置设施标准确定处置。在我们的实验中，水泥砂浆样品使用高温燃烧炉在不同温度条件下加热，提取的氚收集到 0.1 M 硝酸溶液中，然后与液体闪烁体混合，在液体中进行分析。闪烁计数器 (LSC)。经计算，水泥砂浆样品的氚提取率为 90.91% 和 98。54% 对应于分别在 200 °C 和 400 °C 的温度下加热 9 小时。尽管大部分水泥砂浆样品被氚污染，但氚提取率在 400 °C 时接近 100%。
