Effective strategic management is determined by several factors. Firstly, it is influenced by knowledge, experience and skills of all stakeholders responsible for preparation of strategic decisions and decision taking. Secondary and no less important

The emission intensities of 186.21keV, 46.54keV, XL(Bi) and XK(Rn) photons were measured with calibrated HPGe detectors. The efficiency was computed with the MCNP Monte Carlo code and validated using experimental points. Sources of Ra-226 were prepar

The activity of the radionuclide 64 Cu was determined by the efficiency extrapolation method applied to 4π(PC)−γ coincidence counting. The standardisation was performed by software coincidence counting—a digital method for primary activity meas

The activity of 210Pb in a solution with 210Pb-210Po in the radioactive equilibrium was determined through its decay product 210Po by liquid scintillation counting (LSC), which has, after separation, as a pure α emitting nuclide, detection efficienc

Since 2000 the software coincidence counting (SCC) system has been used for activity standardisation of about 15 radionuclides. Their activities were determined by the efficiency extrapolation method applied to 4π (PC)-γ coincidence. Some standardi

Activities of the radionuclides (124)Sb and (152)Eu were determined by the efficiency extrapolation method applied to 4pi(PC)-gamma coincidence counting. The (124)Sb sources were prepared from a solution with the chemical form of 50 microg g(-1) SbCl
