Radiation detection,etic, can be characterized by establishing (a) the energy and (b) the intensity of the radiation. Various detectors relevant to radioisotope techniques can measure one or both of these parameters. In this chapter we will review the most common types of detector and will see that virtually all detect

Radioactive tracer applications,uantitative assay of the tracer after it has left the system. Looking at this principle from an alternative (problem-solving) point of view, if problems of fluid transport can be described in terms of ‘When?’, ‘Where to?’ and ‘How much?’, then they can probably be solved by means of tracer technique

Measurement of flow using radioactive tracers, solid phases may be measured individually or, if required, together. By employing detection equipment of high efficiencey only small amounts of radioactive material are necessary for determinations of high accuracy. Radiological hazards to personnel therefore can be made extremely small, including
