A method for preparing “reagent” for radioactive methyliodide vapors production using an isotopic exchange reaction has been developed. Based on the obtained data of the isotopic exchange efficiency and hydraulic resistance, white fused alumina (700–840 μm) was selected as the carrying agent material for “reagent” production. The radioiodine isotopic exchange dependences on such parameters as temperature, gas flow velocity, and the methyliodide concentration in it were determined. Optimal conditions have been selected to achieve 85% of the isotopic exchange rate in 1 h of the experiment. The obtained data allowed to develop an approach to the test of iodine filters for nuclear power plants and to determine their efficiency.

动态条件下获取放射性甲基碘蒸气的载体选择

已经开发了一种使用同位素交换反应制备用于放射性甲基碘蒸气生产的“试剂”的方法。根据获得的同位素交换效率和水力阻力数据,选择白刚玉(700-840 μm)作为“试剂”生产的载体材料。确定了放射性碘同位素交换对温度、气流速度和其中的甲基碘浓度等参数的依赖性。已选择最佳条件以在实验的 1 小时内实现 85% 的同位素交换率。获得的数据允许开发一种测试核电厂碘过滤器的方法并确定它们的效率。
