Description

The Center for Development of Nuclear Technology (CDTN) of the Brazilian National Nuclear Energy Commission (CNE) has been active in performing tracer studies for about four decades. Both radioactive and stable isotopes, artificial and natural radiotracers, as well as fluorescent dyes have been used. Studies of transport in industrial systems and in the environment (mainly in hydrological systems) have been carried out. This activity started in the late sixties of last century with the measurement of sediment transport in harbors and channels. Most of the work has been connected with field applications to pollution and contamination problems. Lately we have started the application of radiotracers to studies of water movement in oil field, which required an analytical upgrade in our facilities. Besides we have started seven years ago a Graduate Course at CDTN which opens new perspectives for research and cooperation on this subject, as well as many challenges regarding the education and inception of young students in these investigations. The talk will be about of some of these past, present and planned activities.
