Opis:: 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.

Opis:: The high volume air sampler AZA-1000 was built in the Environmental Protection Laboratory of the Andrzej Sołtan Institute for Nuclear Studies. In July 2002, this air sampler AZA-1000 was installed in the Polish Polar Observatory of the Polish Academy of Science in Hornsund, Spitsbergen. The device was built with numerous specific features which make possible to operate such station in extra difficult climatic conditions of polar region. Since July 2002, radioactive aerosols were collected at the Petrianov filter tissue FPP-15-1.5 and measured using high resolution g spectrometry in the Environmental Protection Laboratory at Świerk. The concentration of the airborn, cosmogenic radionuclide 7Be and of other natural and man maid radionuclides like 137Cs was determined. A comparison of the preliminary results with those from the ASS-500 sampling station operating at Świder is presented.
