Measurements of cesium-134 and cesium-137 in Greenland snow together with models of long-range transport have been used to assess radionuclide deposition in the Arctic after the Chernobyl accident. The results suggest that a well-defined layer of radioactive cesium is now present in polar glaciers, providing a new reference for estimating snow accumulation rates and dating ice core samples.
对格陵兰雪层中铯-134和铯-137的测量，再结合长距离传输模型，已被用于评估切尔诺贝利事故后北极地区放射性核素的沉积情况。结果表明，极地冰川中现在存在一层明确界定的放射性铯，这为估算积雪速率和确定冰芯样本年代提供了新的参考依据。
