Abstract
The programme consists of development and testing of metrologically supported laboratory measurement methods, in-situ measurement methods, mathematical models for measurement data processing, models of propagation of contamination in the environment, and development of measuring equipment all based on nuclear measuring methods and techniques. The programme also covers research in radioecology, research of models of radionuclide migration and elemental analyses in various environments (air, water, soil, materials). In the field of gamma-ray spectrometry the programme includes research in characterization of detectors with point sources, development of new methods of calculation of activities of gamma- and X-ray emitters in volume samples in the presence of coincidence summing effects, determination of efficiencies for samples of irregular shapes, characterization of inhomogeneous samples, detection of neutrons with gamma-ray spectrometers and construction of active shields. Concerning the elemental analysis the programme is devoted to development of sensitive techniques based on total reflection X-ray spectrometry for the analysis of environmental, geological and industrial samples (alloys, thin metal layers, new materials, etc.), food products (meat, honey, fruit juices, wines, etc.) and animal food (fermented mixtures, hay, etc.). Intercomparison research of dosimetry standards is focused on improving measurements of small electrical currents in the nanoamperes range and on calibration of ionization chambers in international dosimetry laboratories. Optimization of the measurement system is essential for measurements of small doses in the range of natural background. Intercomparisons are planned partly in cooperation with EUROMET. Improvement of thermoluminiscent dosemeter for measurements in the environment will be continued in order to achieve maximum efficiency for gamma radiation as well as energy compensation for low-energy radiation. Research is directed into testing of different combinations of TLD materials and filters. Finally the programme comprises forecasting of air pollutant concentrations, which is in Slovenia that is characterised by complex terrain, low winds and thermal inversion in the basins and valleys a very interesting problem. For such conditions deterministic models such as "mass consistent" 3 D wind field reconstruction and Lagrangian dispersion models are preferred. Our studies are also focused to prognostic non-hydrostatic models and model based on artificial neural networks.
