The "Resuspension" scenario is designed to test models for atmospheric resuspension of radionuclides from contaminated soils. Resuspension can be a secondary source of contamination after a release has stopped, as well as a source of contamination for people and areas not exposed to the original release. The test scenario describes three exposure situations: (1) locations within the highly contaminated 30-km zone at Chernobyl, where exposures to resuspended material are probably dominated by local processes; (2) an urban area (Kiev) outside the 30-km zone, where local processes include extensive vehicular traffic; and (3) a location 40 to 60 km west of the Chernobyl reactor, where upwind sources of contamination are important. Input data include characteristics of the 137Cs ground contamination around specific sites, climatological data for the sites, characteristics of the terrain and topography, and locations of the sampling sites. Predictions are requested for average air concentrations of 137Cs at specified locations due to resuspension of Chernobyl fallout and for specified resuspension factors and rates. Test data (field measurements) are available for all endpoints.
“再悬浮”情景旨在测试放射性核素从受污染土壤中大气再悬浮的模型。再悬浮可能是释放停止后的二次污染来源，也是未暴露于原始释放的人员和区域的污染来源。该测试情景描述了三种暴露情况：（1）切尔诺贝利高度污染的30公里区域内的地点，在这些地点，对再悬浮物质的暴露可能主要由当地过程主导；（2）30公里区域外的城市地区（基辅），当地过程包括大量的车辆交通；（3）切尔诺贝利反应堆以西40至60公里处的一个地点，上风向污染源很重要。输入数据包括特定地点周围137Cs地面污染的特征、这些地点的气候数据、地形和地貌特征以及采样地点的位置。要求预测由于切尔诺贝利沉降物再悬浮以及特定的再悬浮因子和速率，在指定地点137Cs的平均空气浓度。所有终点都有测试数据（现场测量）。
