Tritium analysis conducted on precipitation samples from Narrabri, New South Wales (1970-1986)

Monthly precipitation samples were collected from the Narrabri meteorological station (altitude 212.4m) for tritium (3H) analysis. Data includes monthly precipitation (mm) and tritium concentration (TU) values.本研究从海拔212.4米的纳拉布里气象站（Narrabri Meteorological Station）采集月度降水样本，用于氚（tritium，3H）分析。该数据集包含月度降水量（单位：毫米，mm）与氚浓度（TU）的观测值。
