Abstract: | Radioactive tracers which have several advantages over conventional tracers made significant contributions to the development
of the injected tracer method in hydrology. A review of the nuclear and the physico-chemical characteristics of the possible
radiotracer compounds leads us to conclude that the most effective groundwater tracers are tritiated water (HTO),82Br− and58Co or60Co as a hexacyanocobaltate complex.
A discussion of the various case studies in India and abroad covering the three groups of applications mentioned helps us
to conclude that well established radiotracer methods with associated interpretational techniques are available for many short
range studies in surface and subsurface hydrology. |
