This book covers the basics of radioanalytical techniques which include sample preparation, irradiation and spectra analysis, and the dimensions and structures of the reactor used for this research. It emphasizes the intake of some essential minerals in some biological samples compared to the appropriate proportion and the amounts recommended by the World Health Organization (W.H.O).It also provides more insight into the method of analyzing samples using Neutron Activation Analysis which is a sensitive analytical technique useful for performing both qualitative and quantitative multi-element analysis with the aid of a research reactor. This work can serve as a guide to the students undergoing their baccalaureate or graduate studies. The novice or researchers in and outside the specialized area would also find this book useful.
