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.

该《核电站邻近人口暴露估计：国家层面汇总》数据集包含了全国范围内，在核电站邻近地区的总人口、城市人口和农村人口的估计值，以及相应的土地面积。该数据集的构建基于全球核电站点位数据集，并利用了距离核电站30公里、75公里、150公里、300公里、600公里和1200公里的缓冲区，结合《全球人口计数网格时间序列估计》第1版（Global Population Count Grid Time Series Estimates, Version 1）的数据，对1990年、2000年和2010年各缓冲区内的总人口进行了估算。此外，采用了《全球城乡映射项目》第1版（Global Rural-Urban Mapping Project, Version 1，简称GRUMPv1）的土地和地理单元面积网格，以估算每个缓冲区内的土地面积。同时，利用GRUMPv1的城市范围网格进一步划分了城市和农村地区的人口及土地面积估计。用于人口、土地面积和城市掩膜的网格均具有1公里（30弧秒）的分辨率。
