The development of effective environmental management programs requires an appropriate assessment of the current state of the environment and contributes to anticipating future changes in the state of the environment. Obtaining such information is one of the main objectives of monitoring the environment, which is subject to anthropogenic stress, including radiological contamination. The distribution of radionuclides and their ability to migrate in ecological chains and concentration in individual parts requires special control in contaminated areas.
The purpose of the study was to analyze the content of radionuclides ( 137Cs and 90Sr) in soils near the settlements of the zone of radioactive contamination of the Volyn region and their spatial differentiation. Priority is given to agricultural lands, soils, crop products, which necessitates the organization of targeted monitoring of the agro industrial complex.
Radioactivity from 137Cs and 90Sr in the soil originating in the Volyn region was studied from 1996 to 2018. Radiation control was carried out on the area of 59852 ha (arable land - 38897 ha, meadows and pastures - 20955 ha).
A significant part of the study area has elevated levels of radioactive contamination. The density of radionuclide contamination of agricultural soils in the settlements of the region has been determined. Density of pollution of all surveyed agricultural lands 137Cs ranges from 0.01 to 2.826 Ci/km2, and 90Sr from 0.01 to 0.048 Ci/km2.
The radiological situation in the Volyn region (Ukraine) remains stable. There are slight fluctuations of 137Cs and 90Sr, which is due to changes in weather conditions, which leads to an increase or decrease in groundwater and as a consequence - the migration of radionuclides. The most polluted were the soils of administrative districts of Manevychi and Liubeshiv.
制定有效的环境管理计划需要对当前环境状况进行适当评估，有助于预测未来环境状况的变化。获取此类信息是环境监测的主要目标之一，环境监测受到包括放射性污染在内的人为压力的影响。放射性核素的分布及其在生态链中的迁移能力和在各个部分的浓缩需要在受污染地区进行特殊控制。
本研究的目的是分析沃伦地区放射性污染区附近定居点土壤中放射性核素（137Cs 和 90Sr）的含量及其空间差异。优先考虑农业用地、土壤和农作物产品，这需要对农业综合企业进行有针对性的监测。
研究了 1996 年至 2018 年来自沃伦地区的土壤中 137Cs 和 90Sr 的放射性。在 59852 公顷的区域内进行了辐射控制（耕地面积-38897 公顷，草地和牧场-20955 公顷）。
研究区域的很大一部分具有较高水平的放射性污染。确定了该地区定居点农业土壤中放射性核素污染的密度。所有调查的农业用地的 137Cs 污染密度范围为 0.01 至 2.826 Ci/km2，90Sr 污染密度范围为 0.01 至 0.048 Ci/km2。
沃伦地区（乌克兰）的辐射状况保持稳定。137Cs 和 90Sr 有轻微波动，这是由于天气条件的变化导致地下水增加或减少，从而导致放射性核素迁移。污染最严重的是马涅维奇和柳比谢夫行政区的土壤。
