Abstract — The paper discusses the forms of anthropogenic radionuclides in natural waters at radiation-contaminated territories. The data were obtained using techniques of cascade filtration and flow field flow fractionation coupled with multi-detector analysis. The size and nature of the colloid and suspended particles in the tunnel waters were determined in the range of 1 to 10 000 nm. The average hydrodynamic diagram of the colloid particles was evaluated. The distribution of anthropogenic radionuclides ( 137 Cs, 90 Sr, 239 + 240 Pu, and 241 Am) between the suspended matter, colloid particles of different size, and dissolved forms was estimated. The fraction of colloid forms of 239 + 240 Pu in the tunnel waters of the mountain massif was typical of each object, differs from one tunnel to another, and does not show any common trends at given geochemical parameters. The migration of radionuclides outside the Degelen Mountains is controlled by the most mobile fraction: particles smaller than 3 nm.

塞米巴拉金斯克试验场德格伦山隧道水域人为放射性核素迁移形式

摘要 — 本文讨论了受辐射污染地区天然水域中人为放射性核素的形式。数据是使用级联过滤和流场流分馏技术结合多检测器分析获得的。隧道水中胶体和悬浮颗粒的大小和性质在 1 到 10 000 nm 范围内确定。评价胶体颗粒的平均流体动力学图。估计了人为放射性核素（137 Cs、90 Sr、239 + 240 Pu 和 241 Am）在悬浮物、不同大小的胶体颗粒和溶解形式之间的分布。山体隧道水域中 239 + 240 Pu 的胶体形式的分数是每个物体的典型特征，从一个隧道到另一个不同，并且在给定的地球化学参数下没有显示任何共同的趋势。放射性核素在 Degelen 山脉外的迁移由最易移动的部分控制：小于 3 纳米的粒子。
