New methods are being employed on the Department of Energy's Savannah River Site to deal with the disposal of tritium, including the irrigation of a hardwood/pine forest with tritiated water from an intercepted contaminant plume to reduce concentrations of tritium outcropping into Fourmile Branch, a tributary of the Savannah River. The use of this system has proven to be an effective means of tritium disposal. To evaluate the impact of this activity on terrestrial biota, rodent species were captured on the tritium disposal site and a control site during two trapping seasons in order to assess tritium exposure resulting from the forest irrigation. Control site mice had background levels of tritium, 0.02 Bq/mL, with disposal site mice having significantly higher tritium concentrations, mean=34.86 Bq/mL. Whole body tritium concentrations of the mice captured at the disposal site were positively correlated with tritium application and negatively correlated with precipitation at the site.
美国能源部的萨凡纳河工厂正在采用新方法处理氚的处置问题，包括用拦截到的污染羽流中的含氚水灌溉阔叶林/松林，以降低氚渗入萨凡纳河支流四英里溪的浓度。事实证明，使用该系统是一种有效的氚处置方式。为评估此项活动对陆地生物群的影响，在两个诱捕季节，在氚处置场地和一个对照场地捕获啮齿动物物种，以评估森林灌溉导致的氚暴露情况。对照场地的小鼠体内氚含量处于背景水平，为0.02贝可/毫升，而处置场地的小鼠体内氚浓度明显更高，平均为34.86贝可/毫升。在处置场地捕获的小鼠全身氚浓度与氚施用量呈正相关，与该场地的降水量呈负相关。
