Population Exposure Estimates in Proximity to Nuclear Power Plants, Country-Level Aggregates

The Population Exposure Estimates in Proximity to Nuclear Power Plants, Country-Level Aggregates data set consists of country-level estimates of total, urban, and rural populations and land area, country-wide, that are in proximity to a nuclear power plant. This data set was created using a global data set of point locations of nuclear power plants, with buffer zones at 30km, 75km, 150km, 300km, 600km, and 1200km, and the Global Population Count Grid Time Series Estimates, Version 1 to estimate the population within each buffer zone for the years 1990, 2000, and 2010. Global Rural-Urban Mapping Project, Version 1 (GRUMPv1) Land and Geographic Unit Area Grids were used to estimate land area within each buffer zone. The GRUMPv1 Urban Extents Grid was used to further delineate population and land area estimates within urban and rural areas. All grids used for population, land area, and urban mask were of 1 km (30 arc-second) resolution.

核电站周边人口暴露评估国家级汇总数据集包含全国范围内、距核电站一定范围内的总人口、城镇人口、乡村人口及土地面积的国家级估算值。本数据集依托全球核电站点位数据集（设置30km、75km、150km、300km、600km及1200km缓冲区）与《全球人口计数网格时间序列估算（第一版）》（Global Population Count Grid Time Series Estimates, Version 1），对1990年、2000年及2010年各缓冲区内的人口开展估算。本数据集采用全球城乡测绘项目第一版（Global Rural-Urban Mapping Project, Version 1，简称GRUMPv1）的土地与地理单元面积网格，估算各缓冲区内的土地面积；并借助GRUMPv1城镇范围网格，进一步区分城镇与乡村区域内的人口及土地面积估算值。本次研究所用的人口、土地面积及城镇掩膜类网格均为1km（30角秒）分辨率。
