Spatial datasets of radionuclide contamination in the Ukrainian Chernobyl Exclusion Zone

Data comprise radionuclide deposition, radioactivity dose measurements, radioactive particle activity and physical characteristic information from soil samples collected within and around the Chernobyl Exclusion Zone (CEZ) following the Chernobyl nuclear accident in 1986.
Data include radiocaesium, radiostrontium and soil chemistry parameters from soils collected in 1997, plutonium isotope measurements in soil samples and soil layers collected in 2000 and 2001, ‘Hot particle’ dataset presenting radionuclide activity and some physical characteristics of ‘hot particles’ extracted from soils collected in the Ukraine and Poland between 1995 and 1997; and Ivankov region data (radionuclide activity concentrations and natural background dose measurements) ) from a survey of the Ivankov region, immediately to the south of the CEZ conducted in 2014.
All samples after gamma-spectrometry measurements are stored at NUBIP and can be made available on request.

本数据集收录1986年切尔诺贝利核事故发生后，在切尔诺贝利隔离区（Chernobyl Exclusion Zone, CEZ）及其周边采集的土壤样品的放射性核素沉降量、辐射剂量测量数据、放射性粒子活度及物理特性信息。
数据集涵盖多批次采样数据：1997年采集土壤中的放射性铯、放射性锶及土壤化学参数；2000年与2001年采集的土壤样品及土层的钚同位素测量数据；1995至1997年间从乌克兰与波兰采集的土壤中提取的“热粒子”（hot particle）数据集，包含该类粒子的放射性核素活度与部分物理特性；以及2014年针对隔离区南侧紧邻的伊万科夫区域开展调查获取的数据，含放射性核素活度浓度与自然本底剂量测量结果。
所有经γ能谱法（gamma-spectrometry）测量后的样品均储存于NUBIP，可应申请提供使用。
