AB  - Kako bi se dobile krive efikasnosti detekcije za In-situ merenja gama zračenja poreklom
iz zemljišta, potrebno je izvršiti odgovarajuće Monte-Karlo simulacije. U simulacijama
je korišćena gustina zemljišta od 1,046 g/cm3
, dok je elementalni sastav zemljišta u
kojem se generiše gama zračenje bio: O - 47%, Si - 35%, Al - 8%, Fe – 3,9%, C – 2,1%,
Ca – 1,4%, K – 1,3%, N – 0,6%, Mg – 0,6%, N – 0,1%. Matrica zemljišta je predstavljena cilindričnom zapreminom prečnika 1,5 m i debljine 0,5 m, iznad koje je na visini
od 1 m postavljen germanijumski detektor. Razmatrane su homogene distribucije različitih radionuklida (Ra-226, Th-232, K-40) u matrici zemljišta. U simulacijama su
dobijeni i analizirani odgovarajući gama spektri, koji uz podatke o simuliranim efikasnostima detekcije, omogućuju poređenje sa realnim eksperimentalnim merenjima i
praktičnu primenu simulacionih rezultata.
AB  - In this work, the Monte-Carlo simulations for In-Situ gamma spectrometry of soil were
performed. The simulated gamma spectrum, originated from K-40, as well as from
members of Th-232 chain, and daughters of Ra-226, was obtained. We obtained the
corresponding detection efficiency curve for HPGe detector, which can be applied for
In-Situ measurement of radionuclide concentration in soil, assuming uniform
radionuclide distribution.

AB  - 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 concentrations, 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.

AB  - The results of a detailed study of the low-level performance of a NaI(Tl) shield added to an iron shielded HPGe spectrometer are presented. Both the slow and the fast anticoincidence gating modes were tested, the slow mode being found better suited for general low-level spectroscopy applications. In long runs the stability of the system in this mode is satisfactory. The anticoincidence action of the NaI(Tl) shield lowers the integral background of the iron shielded HPGe detector in the energy range from 30 keV to 2 MeV by a factor of 6.5, and suppresses the continuum above 150 keV by a factor larger than 10.

AB  - The gamma spectrum of Cs-137 was measured by means of a low-level shielded and Compton-suppressed HpGe spectrometer. The gamma line with the energy 283.4 keV and absolute intensity of 5.3(14)X10(-6) was found. It was concluded that the 283.4 keV intermediate level in Ba-137 [seen earlier in (n,ngamma) measurements] is populated in the beta decay of Cs-137 with the comparative half-life of log ft=15.3(3).
