This series provides a uniquely comprehensive and integrated coverage of analytical chemistry, covering basic concepts, classical methods and instrumental techniques. The learning objectives of each text are clearly identified and the student’s understanding of the material is constantly challenged by self assessment questions with reinforcing or remedial responses. The overall objective of Analytical Chemistry by Open Learning is to enable the student to select and apply appropriate methods and techniques to solve analytical problems, and to interpret the results obtained. Radiochemical Methods This book presents the analytical uses of radioactive isotopes within the context of radiochemistry as a whole. It is designed for scientists with relatively little background knowledge of the subject. Thus the initial emphasis is on developing the basic concepts of radioactive decay, particularly as they affect the potential usage of radioisotopes. Discussion of the properties of various types of radiation, and of factors such as half-life, is related to practical considerations such as counting and preparation methods, and handling/disposal problems. Practical aspects are then considered in more detail, and the various radioanalytical methods are outlined with particular reference to their applicability. The approach is ‘user friendly’ and the use of self assessment questions allows the reader to test his/her understanding of individual sections easily. For those who wish to develop their knowledge further, a reading list is provided.
