^(210)Po法在铀矿勘察中的应用

Application of ^(210)Po method in prospecting uranium

^(210)Po作为放射性测量方法广泛运用在铀矿勘察中。铀元素在衰变过程中形成能溶于水惰性气体222Rn,当发生构造运动时,含222Rn地下水会沿着构造运动产生的断裂等通道运移至地表,然后经过一系列的长、短期衰变形成稳定的^(210)Po,吸附在土壤中。通过^(210)Po测量可以推断断裂构造的位置,间接的指导铀矿勘察工作。本文通过土壤^(210)Po测量大致查明研究区内,北东向断裂为主干断裂,并发育多条北西向次级断裂。

^(210)Po radioactive measurement method,and is used to prospecting uranium.222Rn is formed when the uranium decay,and dissolve in water.222Rn will be transported to the ground,through the track,for example fracture and so on.According to a series of decays and form^(210)Po which is a stable element,and adorbed on the soil.So according to measurement of^(210)Po infer the location of the fracture and indirect the work of uranium prospecting.According to measurement of^(210)Po in this paper ascertain the main fracture locateNE and there are some secondary fracture which locate NW in the research area.
