Tree ring series were collected from the vicinity of a Hungarian radioactive waste treatment and disposal facility and from a distant control background site, which is not influenced by the radiocarbon discharge of the disposal facility but it represents the natural regional (14)C level. The (14)C concentration of the cellulose content of tree rings was measured by AMS. Data of the tree ring series from the disposal facility was compared to the control site for each year. The results were also compared to the (14)C data of the atmospheric (14)C monitoring stations at the disposal facility and to international background measurements. On the basis of the results, the excess radiocarbon of the disposal facility can unambiguously be detected in the tree from the repository site.
从匈牙利放射性废物处理与处置设施附近以及一个遥远的对照背景站点采集了树木年轮序列。该对照背景站点不受处置设施放射性碳排放的影响，但代表了自然区域的（14）C水平。通过加速器质谱法（AMS）测量了树木年轮纤维素含量的（14）C浓度。每年将处置设施的树木年轮序列数据与对照站点的数据进行比较。结果还与处置设施大气（14）C监测站的（14）C数据以及国际背景测量数据进行了比较。根据结果，可以明确在储存库站点的树木中检测到处置设施的过量放射性碳。
