这项模拟研究考察了1969至1988年间从塞拉菲尔德排放的137Cs在英国周围陆架海内的扩散情况,以及切尔诺贝利事件(1986年4月)后的大气沉积情况。计算的分布与观测的分布之间的密切一致增加了对冲刷时间的估计的信心,冲刷时间是确定污染物浓度的基本参数。此外,这项研究第一次证实了大气扩散模型所提供的切尔诺贝利核泄漏的估计。
This modelling study examines the dispersion within the shelf seas surrounding the UK, of 137Cs discharged from Sellafield between 1969 and 1988 together with the atmospheric deposition following Chernobyl (April 1986). The close agreement obtained between computed and observed distributions lends confidence to estimates of flushing times-fundamental parameters in determining pollutant concentrations. Moreover, this study confirms, to first-order, the estimates of Chernobyl fall-out provided by atmospheric dispersion models.
