本世纪六十年代中期,核裂变径迹技术开始应用于地球化学研究中。由于它对微粒微量及低含量样品的铀、钍分折具有高灵敏度,很快得到地球化学工作者的重视,并在
In the mid-1960s, nuclear fission track technology began to be used in geochemical research. Because of its high sensitivity to uranium and thorium fractions in both trace and low-content samples, it is rapidly gaining attention by geochemical workers
