Tritium generated in a mercury target is a source of potential exposure of personnel at high-energy accelerator facilities. Knowledge of the chemical form of tritium is necessary to estimate the internal doses. We studied the tritium generation upon thermal neutron irradiation of a mercury target modified into liquid lithium amalgam to examine the ratio of tritiated water ([3H]H2O) and tritiated hydrogen ([3H]H2). The ratio between [3H]H2O and [3H]H2 generated in lithium amalgam was 4:6 under these experimental conditions.
在汞靶中产生的氚是高能加速器设施中人员潜在暴露的一个来源。了解氚的化学形态对于估算内照射剂量是必要的。我们研究了将汞靶改性为液态锂汞齐后经热中子辐照时的氚生成情况，以考察氚化水（[³H]H₂O）和氚化氢（[³H]H₂）的比例。在这些实验条件下，锂汞齐中产生的[³H]H₂O与[³H]H₂的比例为4:6。
