As a result of investigations carried out on the territory of Semipalatinsk Test Site, tritium was found in different environmental objects--surface and ground waters, vegetation, air environment, and snow cover. The analysis of the data obtained has shown that contamination of environmental objects at the Semipalatinsk Test Site with tritium is associated with the places where underground nuclear tests were performed. Since tritium can originate from an activation reaction and be trapped by pock particles during a test, it was decided to examine the soil in the sites where surface and excavation tests took place. It was found that the concentration of tritium in soil correlates with the concentration of europium. Probably, the concentration of tritium in the soil depends on the character and yield of the tests performed. Findings of the study have revealed that tritium can be found in soil in significant amounts not only in sites where underground nuclear tests took place but also in sites where surface and excavation nuclear tests were carried out.
对塞米巴拉金斯克试验场区域进行调查的结果显示，在不同环境物体中发现了氚，包括地表水和地下水、植被、空气环境以及积雪。对所获数据的分析表明，塞米巴拉金斯克试验场环境物体受到氚污染与进行地下核试验的地点有关。由于氚可源自活化反应并在试验期间被微粒捕获，因此决定对进行地表和挖掘试验地点的土壤进行检测。结果发现，土壤中氚的浓度与铕的浓度相关。土壤中氚的浓度可能取决于所进行试验的性质和产量。该研究结果表明，不仅在进行地下核试验的地点，而且在进行地表和挖掘核试验的地点，土壤中都能发现大量的氚。
