Measuring alpha and beta activity of filter and swab samples with LSC

Original language description

Analysis of alpha and beta emitters in aerosol filters and swabs of different materials by liquid scintillation counter is discussed. This method appears suitable for fast determination of activity of radionuclides due to direct alpha and beta separation, measurement in 4? geometry and without sample treatment. The selected group of radionuclides was chosen with respect to military significance, radiotoxicity, and possibility of potential misuse. 90Sr and 239Pu were selected as model radionuclides. Three types of filters were examined, and the attention was also focused on optimizing the type and volume of LSC cocktail. The efficiencies for 239Pu and 90Sr were 90 % and 79 %, respectively. This method was the most effective for the glass fiber filters measured with the MaxiLight cocktail.
