Analytical importance of some secondary and threshold reactions induced in nuclear reactors

The feasibility of threshold and secondary reactions as analytical alternatives for some special elements is discussed. Examples of applications, at the author's laboratory for determination of lithium, fluorine, titanium and thallium are presented. The importance of threshold reactions as interferences of capture reactions is also discussed. The pairs of elements where the interference was experimentally evaluated were calcium and titanium, scandium and titanium; manganese and iron; copper and zinc.
