摘要

Spergularia rubra (L.) J. Presl & C. Presl 具有菌根抗性，可增加铀吸收。结果表明，35% 的 238U 保留在碳酸盐部分，59% 保留在残留或非反应部分。226Ra 则显示出不同的模式，平均 19% 存在于有机物部分，10% 存在于碳酸盐化合物中，其余 71% 存在于残留物部分。研究发现，238U 和 226Ra 在土壤组分和 Spergularia 中的活性浓度之间的关系在统计学上分别代表碳酸盐和有机物组分。

Model of U and 226Ra uptake by Spergularia rubra (L.) J. Presl & C. Presl in an area affected by Cu ore mining

Spergularia rubra (L.) J. Presl & C. Presl has a mycorrhizal resistance that leads to increased uranium uptake. The results show that 35% of the ²³⁸U is retained in the carbonate fraction and 59% in the residual or non-reactive fraction. ²²⁶Ra shows a different pattern with an average association of 19% in the organic matter fraction, 10% in the carbonate compounds and the remaining 71% in the residual fraction. The relationships between the activity concentrations of ²³⁸U and ²²⁶Ra in the soil fractions and in Spergularia were found to be statistically representative of the carbonate and organic matter fractions, respectively.
