水泵抽取的海水通过锰纤维富集柱,富集体积达 400 L 以上。用 HPGe γ谱仪直接测定样品中的镭同位素 224Ra、226Ra 和228 Ra。研究了胶州湾水体镭同位素的分布。
Abstract
The radium isotopes were preconcentrated in-situ from large seawater that was pumped through Mn-fiber cartridge.224Ra
226Ra and 228Ra in cartridges were counted using HPGe γ spectrometer directly. This method was used to study radium isotopes distribution in seawater of Jiaozhou Bay.
