研究指出,在氟化钠中不同的元素,对铀螢光的影响不同;而且其影响还决定于它们在珠球中的含量[表1]。根据影响的程度,我们将所研究过的元素分为五组。第一组:是指它们在珠球中的含量很大时,对铀螢光没有影响,或者是影响可以忽略的元素,这样的元素有Li,Na,K,Rb,Cs,Zn Ti,S,Mo,W,Cl,Br,I。第二组:是指它们在5毫克珠球中的含量为1·10~(-6)至1·10~(-4)克时,即有影响的元素,这样的元素有Cu,Be.Mg,Ca,Sr,Cd,Ba,B,Si,Zr,Th,P,Se
The study indicates that different elements in sodium fluoride have different effects on uranium fluorescence, and their effects are also dependent on their content in the beads [Table 1]. According to the degree of influence, we divide the elements studied into five groups. The first group means that they have no effect on uranium fluorescence or have a negligible effect on the content of the beads when they are abundantly contained in beads. Such elements include Li, Na, K, Rb, Cs, Zn Ti, S , Mo, W, Cl, Br, I. The second group: refers to their content in the 5 mg beads in the 1.10 ~ (-6) to 1.10 ~ (-4) grams, the influential elements, such elements are Cu, Be. Mg, Ca, Sr, Cd, Ba, B, Si, Zr, Th, P, Se
