Alpha spectrometry for measuring activity of glass-embedded 210PO isotope.
Measurements of exposure to radon are performed using numerous research methods which register either temporary or periodic radon concentrations. At the end of the 1990s reports on the possibility of defining past exposure to radon on the basis of measurement of the contents of 210Pb embedded in surface layer of glass were published. The registration of alpha particles emitted with glass was made using the spectrometric system. Use of the system for alpha spectroscopy leads finally to a significant lowering of the bottom threshold of detection and limits the influence of the negative background on the examined glass.
