Investigations following five international expeditions to the Kara Sea have shown that no radiologically significant contamination has occurred outside of the dumping sites in Novaya Zemlya bays. Increased levels of radionuclides in sediment have only been observed in Abrosimov and Stepovoy Bays very close to dumped containers. Evaluations of radionuclide inventories in water and sediment of the open Kara Sea and Novaya Zemlya bays as well as soil from the shore of Abrosimov bay have shown that radionuclide contamination of the open Kara Sea is mainly due to global fallout, with smaller contributions from the Sellafield reprocessing plant, the Chernobyl accident run-off from the Ob and Yenisey rivers and local fallout. Computer modelling results have shown that maximum annual doses of approximately 1 mSv are expected for a hypothetical critical group subsisting on fish caught in the Novaya Zemlya bays whereas populations living on the mainland can be expected to receive doses at least three orders of magnitude lower.
对喀拉海进行的五次国际考察结果表明，在新地岛海湾的倾倒场所以外，未发生具有显著放射性的污染。仅在非常靠近倾倒容器的阿勃罗西莫夫湾和斯捷波沃伊湾观察到沉积物中放射性核素水平升高。对喀拉海开阔海域、新地岛海湾的水和沉积物以及阿勃罗西莫夫湾海岸土壤中的放射性核素存量评估表明，喀拉海开阔海域的放射性核素污染主要源于全球沉降，塞拉菲尔德后处理厂、鄂毕河和叶尼塞河因切尔诺贝利事故产生的径流以及局部沉降的影响较小。计算机模拟结果表明，假设存在一个以新地岛海湾捕获的鱼类为生的关键群体，预计其年最大剂量约为1毫希沃特，而居住在大陆的人群预计接受的剂量至少低三个数量级。
