Absolute determination of low-energy X-ray emission rates with a proportional counter

A defined-solid-angle proportional counter has been designed for the absolute determination of X-ray emission rates between 2 keV and 10 keV. The main features of the counter are described in this work, and spectra of two radionuclides with low-energy X-ray emissions are presented. The activity conc...

Description
Summary:A defined-solid-angle proportional counter has been designed for the absolute determination of X-ray emission rates between 2 keV and 10 keV. The main features of the counter are described in this work, and spectra of two radionuclides with low-energy X-ray emissions are presented. The activity concentration of an 55Fe solution was determined by measuring the emission rate of three samples and using tabulated emission probabilities. This activity concentration is compared with the value obtained by liquid scintillation counting, and an excellent agreement has been found. •Proportional counter for absolute measurement of low-energy X-rays designed and built.•Performance tested measuring 55Fe and 54Mn X-ray spectra.•Activity concentration of an 55Fe solution has been measured.
