Opis:: Our aim was to obtain and isolate the carrier-free gamma emitter, 54Mn. Manganese-54 was produced via cyclotron activation in the 51V(alfa,n)54Mn reaction, and separated from HCl solution on Dowex-50 . 8 resin. The effectiveness of chemical separation was checked using the internal tracer 48V, produced in a cyclotron via the natTi(p,xn)48V reaction. The microcomponent 54Mn was eluted from the column with 3 M HCl, and vanadium with a 0.1 M HCl/ethanol/H2O2 mixture. The pair Ti/48V was separated on Dowex-50 . 8, using 0.03 M HClO4 as the eluent for 48V and 1 M HClO4 for natTi. The carrier-free 54Mn was of 99.9% radionuclide purity. In separation of the carrierfree pair 54Mn/48V, the recovery yield was 98.7% for 54Mn and 96.4% for 48V.

Opis:: The method of obtaining carrier free tracers, 85Sr and 83Rb from proton-irradiated natRbCl target is described. The separation of the radionuclides was done using Sr-Resin, the resin based on a crown ether. Current and some other possible applications of the tracers are discussed.

Opis:: The artificially produced isotopes of polonium are valuable tracers for radiochemical procedures for the determination of natural 210Po. In this work, the isotopes of polonium (206Po to 208Po) were produced by activation of metallic bismuth targets with 40 MeV protons. The thick target yield of 206Po was 16 MBq/ěAh. Polonium was separated from bismuth by a thermochromatographic method under reduced pressure in static conditions. The bismuth target can be considered as the multiple-use material.

Opis:: In this work empirical functions which relate the full-energy peak efficiency with sample height, energy, matrix composition and bulk density for voluminal samples in a cylindrical counting geometry were found. Accurate determination of the radioactivity of gamma-emitting radionuclides in environmental samples requires taking into account self-absorption. For the obtained self-absorption correction factor, a direct transmission method was chosen. Finally, this paper proposes a simple correlation between the self-absorption correction factor and the bulk density and height of the measured sample for a given energy.
