W Katedrze Inżynierii Materiałów i Procesów Budowlanych Politechniki Śląskiej przez wiele lat były prowadzone prace naukowo-badawcze obejmujące m. in. promieniotwórczość naturalną kruszyw budowlanych. Dotyczyły one kruszyw pochodzenia naturalnego oraz kruszyw sztucznych, powstających w procesie wypału zgranulowanych i wysuszonych surowców ilastych i/lub mineralnych odpadów przemysłowych. W artykule zaprezentowano wybrany wycinek uzyskanych wyników wzmiankowanych prac.

This paper is devoted to the comprehensive description of the implementation of the RODOS System in the Center for Radiological Events (CEZAR) of the National Atomic Energy Agency in Poland. First the history of the RODOS Project of the European Commission is presented, followed by the description of the structure and modules of this comprehensive Software Package, aimed to assist in the management of the nuclear emergency problems following the nuclear accident in Europe. Then the adaptation of the software to Polish national conditions is explained taking into account the radiological data prevailing on the Polish territory. All the data bases connected with meteorology, contamination transport parameters in humans and their ecological systems have been collected and applied to meet the specific dietary habits, soil structures, agricultural situation and other specific condition in this country. Those data have been introduced into the system after appropriate adaptations to the specific requirements of the modules of the RODOS System. Furthermore, the network system connected with the RODOS prc-operational version in CEZAR is described enabling on-line cooperation with the Institute of Meteorology and Water Management (IMWM) and the Central Laboratory for Radiological Protection (CLOR) as well as with the Institute of Atomic Energy (IAE), which plays the role of Technical Support Organization with respect to this System. IAE has participated in the development of the RODOS System within tlie 4-th and 5-th Research Frameworks of EU and acknowledges here with gratitude the Implementation Grant from the State Committee of Scientific Research and National Atomic Energy Agency in Poland. This Grant has created the basis for the implementation of the RODOS System in Poland within tlie framework and assistance of the ECHO contract of the EU.

The influence of leaf feeding with nitrogen in urea solution and application of chlorocholine chloride (CCC) on the uptake of 137Cs by spring wheat from the investigated soil samples and through leaves was studied in pot experiments. Spray application of nitrogenous fertilizer in urea solution with additional use of growth retardant were found to have brought about an increased accumulation in the grain of 137Cs taken up by the plants from the contaminated soil. It was found that 2–4 times more 137Cs accumulated in wheat grain from leaves contaminated in the flowering stage in comparison with that found in the grain of plants contaminated in the propagation stage. The application of leaf feeding with urea and chlorocholine exerted no influence on the accumulation of 137Cs in grain if the plants had been contaminated superficially in their earlier development stages. Contamination with 137Cs sprayed upon the plants after application of chlorocholine chloride appeared to pass to the spring wheat crops more readily.
