This article reflects a partial resume of research in applied nuclear physics performed in our country during the last 50 years. As the first example we can quote the successes of B. Lalovic and V. Ajdacic in developing and applying new instrumentation for nuclear measurements. V. Ajdacic developed the long pipe method for the absolute measurement of neutron flux in power reactors. Together with B. Lalovic, he managed, among the first few people in the world, to produce semiconductor Ge(Li) spectrometers. Practically all of the measuring equipment currently being used by the Novi Sad nuclear physics group has been purchased with funds obtained for radioecological investigations, so that actually the applied nuclear spectroscopy kept alive the experimental work. Background reduction, sensitivity increase, detection efficiency calibration and development of coincidence techniques are research directions through which this group tries to measure as low as possible radionuclide concentrati...ons, as well as the probability of exotic rare nuclear processes. Very strong radiation sources in Vinca have been used for some decades for sterilization of food and medical equipment. Hyperfine interactions of nuclei with the electric and magnetic fields of their crystal environment give extensive possibilities to investigate phenomena in solid-state physics and new materials. The highly advanced techniques of perturbed angular correlations and Mossbauer spectroscopy were adopted here as bridges between nuclear and condensed matter physics. The bridges are partly destroyed, partly still standing, but almost nobody passes them.
