为了测定不平衡矿石中铀的真实含量,必须将两种方法结合一起使用,例如γ和β测量方法。测定铀的这种方法的依据是,铀系中镭前、后的β和γ放射体之间有着不同的比例关系。大家知道,在铀系中,镭以前和以后的元素之间的β辐射几乎相等,而γ辐射的98％则是镭的衰变产物所放出的。矿石中钍的存在,会使铀系的β和γ放射体的比例失真,所以用综合β-γ测量方法分 In order to determine the true amount of uranium in an unbalanced ore, two methods must be used in combination, such as gamma and beta measurements. This method of determining uranium is based on the fact that uranium systems have different proportions of beta and gamma emitters before and after radium. As we all know, in the uranium system, radium before and after the elements of the beta radiation is almost equal to, and 98% of the gamma radiation is radium decay products released. The presence of thorium in the ore distorts the proportions of uranium-based beta and gamma emitters. Therefore, using the integrated beta-gamma method
