This low-level radionuclide metrology research work was carried out within the Joint Danube Survey 4 (JDS4), coordinated in 2018-2020 by the International Commission for the Protection of the Danube River (ICPDR). The gamma-emitting radionuclides of the sediment samples were analysed by low-level gamma-ray spectrometry. The activity concentration of Sr was determined by liquid scintillation counting (LSC) after isolating the radio-strontium using a new radiochemical separation method. The results of the radiometric analysis of Sr, Cs and naturally occurring radionuclides K, Pb, Ra, Ra in recent riverbed sediment are presented and discussed focused on public health.
这项低水平放射性核素计量学研究工作是在多瑙河联合调查4（JDS4）中开展的，该调查在2018 - 2020年由国际多瑙河保护委员会（ICPDR）协调。通过低水平伽马射线光谱法分析沉积物样本中的伽马发射放射性核素。在使用一种新的放射化学分离方法分离出放射性锶后，通过液体闪烁计数法（LSC）测定锶的活度浓度。给出并讨论了近期河床沉积物中锶、铯以及天然存在的放射性核素钾、铅、镭、镭的辐射分析结果，重点关注公共健康。
