南极大陆约占地球总面积的9％,总面积为1350万km~2,但只有约2％地区是无冰的,其余大片地区均被冰雪覆盖。在这块大陆上铀矿资源至今仍未完全勘查过。1976年,作为美国南极研究计划的一部分,第一次在南极进行系统的铀资源评价,定名为“南极国际放射性测量”。这项计划是由美国堪萨斯大学和联邦德国的科学家联合执行的。测量持续了三个南极野外季节,并将延续工作四年。由于冰雪覆盖、露头分散、气候严寒、地形恶劣,使得在南极开展测量活动既困难又费用高昂。自从1976年开始工作以来,据估计,开展放射性测量的地区为一块长9000 km,宽约50 m的条带,实际测量面积只有225 km~2,占南极大陆总出露面积不足0.1％。
The Antarctic continent accounts for about 9% of the Earth’s total surface area, with a total area of 13.5 million km2. However, only about 2% of the Antarctic continent is ice-free and the rest of the area is covered by snow and ice. Uranium resources in this continent have not yet fully explored. In 1976, for the first time in the Antarctic, a systematic evaluation of uranium resources was conducted as part of the United States Antarctic Research Program and is named “Antarctic International Radiometric Survey.” The program is jointly implemented by scientists at the University of Kansas and the Federal Republic of Germany. The measurement lasted for three Antarctic field seasons and will continue for four years. Due to snow and ice cover, outcrops, cold climate and poor terrain, measurement activities in the Antarctic are both difficult and costly. Since its commencement in 1976, it has been estimated that the radiometric survey area is a strip of 9000 km long and 50 m wide with an actual survey area of only 225 km 2, accounting for less than 0.1% of the total exposed area of the Antarctic continent.
