    Radiotracer applications: case studies from four continents
    (International Atomic Energy Agency, 2015-01-01) Jung, SH; Bandeira, JV; Brisset, P; Wörman, A; Airey, PL; Hughes, CE
    Case studies are a simple way to demonstrate how radiotracers can be successfully used in the environment in addressing water resources contaminant transport and coastal management issues. This paper presents ten case studies from Korea, France, Brazil, Hong Kong, Australia, Belgium and Sweden using a variety of radiotracers including 99mTc, 198Au, 3H, 82Br, 32P, 175+181Hf, 160Tb, 51Cr(III), 65Zn, 54Mn and 35S. These studies address physical transport processes such as dispersion and mixing, reactive transport and adsorption and contaminant uptake. Traced components include water, effluent, nutrients, contaminants and mud in rivers, lakes, wetlands and coastal waters.

    Radiotracer methodology
    (International Atomic Energy Agency, 2015-01-01) Brisset, P; Airey, PL; Jung, SH; Hughes, CE
    Methods for the use of radiotracers in aquatic environments have been established over the past five decades. The basic principles involve definition of the system or problem to be investigated, selection of a suitable tracer, design of tracer deployment and measurement systems and analysis of the data collected to address the initial problem. These aspects are covered in detail in this paper covering the current state of the art in tracer technology. New developments in the use of nano-particle tracers are also addressed. © The authors.
