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 experimental technique based on scanning of positron implantation profile, hereafter referred to as the DSIP is used for the determination of linear absorption coefficient for positrons emitted from a 48V source into water. This coefficient is equal to 1/(299š62) mi m–1. The determined value is in agreement with the one obtained from the computer simulations using the well known EGS nrc 4.0 and GEANT4 codes. The experimental technique was used for the determination of linear absorption coefficients for 48V positrons in materials of biological origin. The presented data can be useful for PET studies because of similarities of the 18F and 48V positron implantation profiles.
