Uranium concentration in manganese nodules recovered from the Pacific Ocean during the 43th expedition of the R/V Vityaz

Uranium was measured in manganese nodules by alpha-ray spectroscopy after grinding and dissolution. The study included the separation of various rinds (layers) in the rind of the nodules in order to appreciate its various along with manganese nodules growth.

本研究经研磨与溶解前处理后，采用α射线能谱法（alpha-ray spectroscopy）对锰结核（manganese nodules）中的铀元素进行测定。研究过程中对锰结核外壳的不同壳层进行分离，以解析锰结核生长过程中的各类特征。
