本文介绍了切尔诺贝利核电站事故后，德国亚琛环境中放射性核素的迁移情况。这些测量包括/sup 131/I、/sup 137/Cs、/sup 134/Cs、/sup 103/Ru和/sup 132/Te在空气中的活度浓度和活度尺寸分布，以及/sup 131/I和/sup 137/Cs在地面和植被中的沉积。除了气态碘物质外，所有核素都是粒子束缚的。沉积速度来自测量，连同雨水中的活性浓度和清除系数。结果进行了比较，从模型的干和湿沉积的计算。（英国）。
Results are presented on the transport of radionuclides in the environment of Aachen, Germany, after the Chernobyl reactor accident. The measurements include activity concentrations and activity size-distributions in the air for /sup 131/I, /sup 137/Cs, /sup 134/Cs, /sup 103/Ru and /sup 132/Te, and deposition on the ground and vegetation for /sup 131/I and /sup 137/Cs. Besides gaseous iodine species, all nuclides were particle bound. Deposition velocities derived from the measurements are given, together with activity concentrations in rainwater and the scavenging coefficient. The results are compared with calculations from models of dry and wet deposition. (U.K.).
