在新西兰霍基蒂卡对空气和雨水中天然 7Be 的浓度进行了为期一年的监测。空气中的平均浓度为 3.1±1.3 mBq m−3，即新西兰霍基蒂卡的平均值。空气中的平均浓度为3.1±1.3 mBq m−3，雨水中的平均浓度为2600±1200 Bq m−3，平均总沉积量估计为130±99 Bq m−2wk−1。大部分 7Be 是湿沉积的并且冲刷率与沉淀量无关。在这个高降雨点，每周湿沉降通量与每周降水量之间存在显着的线性关系。
Concentrations of natural7Be in air and rainwater were monitored for one year at Hokitika, New Zealand. The mean airborne concentration was 3.1±1.3 mBq m−3, the mean Hokitika, New Zealand. The mean airborne concentration was 3.1±1.3 mBq m−3, the mean concentration in rainwater was 2600±1200 Bq m−3, and the mean total deposition was estimated to be 130±99 Bq m−2wk−1. Most of the7Be was wet deposited and the washout ratio was independent of precipitation amount. A significant linear relationship exists between the weekly wet deposition flux and weekly precipitation at this high-rainfall site.
