heal.abstract	The present study demonstrates radioactive tracer technology as a reliable source of information in scaling experiments in porous media. The critical information obtained from such experiments is the induction time of scaling and the profile of the scale deposition along the deposition medium. In a series of calcite scaling experiments in sandpacks,47Ca2+ was used as a tracer to monitor CaCO3 precipitation. In these experiments the induction time and the distribution of scale deposition were studied as a function of saturation ratio, temperature, flow velocity, the presence of Mg ions and the type of packing material. The results show that the radiotracer method gives a fast response to scaling events. The technique is applicable for dynamic scaling investigations in any flowing system in porous media and constitutes a valuable tool for further studies of scaling mechanisms involved in processes occurring in a variety of systems (oilfield, geothermal, desalination etc).	en
