Abstract

Uranium, thorium and rare earth elements (REEs) in soil samples contaminated by Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident was determined using inductively coupled plasma-mass spectrometry (ICP-MS). This information provides knowledge about concentration levels of REEs in soil samples as a background data after FDNPP accident. Chondrite-normalised REEs pattern does not show enrichment in concentrations of REEs, which could be related to FDNPP accident. The high concentration of these elements at few sampling points may be due to soil formation process from granitic rocks.

摘要

采用电感耦合等离子体质谱法（ICP-MS）测定了受福岛第一核电站（FDNPP）事故污染的土壤样品中的铀、钍和稀土元素（REEs）。该信息提供了关于FDNPP事故后土壤样品中REEs浓度水平的知识，作为背景数据。球粒陨石标准化REEs模式未显示REEs浓度的富集，这可能与FDNPP事故有关。少数采样点这些元素的高浓度可能归因于花岗岩形成土壤的过程。
