Neutronová aktivační analýza pomocí generátoru 14 MeV neutronů

Abstract

The purpose of this thesis is to examine the neutron flux of Thermo Fisher Scientific MP 320 14 MeV Neutron generator, construct pneumatic transport system for samples in the Laboratory for Neutron Activation Analysis and Gamma Spectrometry in Ostrava and present first detection of short-lived radionuclides using 14 MeV neutrons. The determination of neutron flux was performed by Texas convention technique. Successfully constructed pneumatic transport system was used during neutron activation of samples in which short-lived radionuclides were formed, to obtain gamma spectra of activated samples using scintillation spectrometer. Masses of selected isotopes in sample contents were analyzed by means of the results from neutron flux measurement and gamma spectrometry data of activated samples.
