1972年法国科学家从对加蓬出产的铀矿石的分析中发现其同位素组成与正常的不一样,同位素含量为0.4％的矿石,迥异于正常的0.7％的矿石。经过长期的测试和研究后证明:由于天然原子反应堆的存在,轻同位素被裂变掉了。反应堆的存在,需要三个条件;高纯度的铀235燃料、使中子减速的介质和某种冷却介质。研究表明:在20亿年前这些条件是存在过的,大雨造成岩石侵蚀把铀分离开来。然后沉淀淤积于极化的砂层中。在粘土层保护下厚达6米的砂层浓缩了铀(大约只含32％的铀235同位素)。随着时间的推移,铀
In 1972, the French scientists found that the isotopic compositions of uranium ore from Gabon were different from the normal ones. The ore with 0.4% isotope content is different from the normal 0.7% ore. After long-term tests and studies, it has been proved that light isotopes are fissioned due to the existence of natural atomic reactors. The existence of the reactor requires three conditions; high-purity uranium 235 fuel, neutron deceleration medium and some cooling medium. Research shows that these conditions existed more than two billion years ago, and heavy rains caused rock erosion to separate uranium. It is then deposited in a polluted sand bed. Uranium is enriched in sand layers up to 6 meters thick (about 32% uranium 235 isotopes) under the protection of clay layers. Uranium over time
