Applications of accelerators in physics and chemistry

Accelerator beams are becoming increasingly used in a variety of applied fields, such as material testing, space simulation, radiodiagnostic and radiotherapeutic work, and elemental analysis. Criteria necessary to establish a viable program based upon such a technique are proposed. In light of these criteria, programs involving elemental analysis of environmental, medical and industrial samples are discussed, with special emphasis on methods for reducing the disadvantages associated with an accelerator‐based technique.
