A dispersion of radionuclides (3H, 90Sr, 137Cs, 239Pu) potentially released from the Mururoa and Fangataufa atolls through the South Pacific Ocean has been studied by means of computer models. The models used consisted of three differently structured compartmental models for the regional field and a hydrodynamic world ocean model for the far-field simulations. The outcome of regional modelling is predicted activity concentrations with time in different regions of French Polynesia (over up to 10,000 years for plutonium). The far-field model simulates large-scale dispersion in the South Pacific Ocean over periods of up to 50 years. The overall result suggests that there will not be radioactive contamination of any radiological interest at inhabited sites in French Polynesia or anywhere else in the ocean at present or in the future.
已通过计算机模型研究了穆鲁罗瓦环礁和方阿陶法环礁可能通过南太平洋释放的放射性核素（氚、锶-90、铯-137、钚-239）的扩散情况。所使用的模型包括用于区域范围的三个结构不同的分区模型以及用于远场模拟的一个水动力世界海洋模型。区域建模的结果是预测法属波利尼西亚不同区域随时间变化的活度浓度（钚长达10000年）。远场模型模拟了长达50年期间南太平洋的大规模扩散。总体结果表明，目前或未来，法属波利尼西亚有人居住地区或海洋中其他任何地方都不会出现具有任何放射学意义的放射性污染。
