Abstract
The characteristics of a modified scintillation detector based on a large NaI(Tl) crystal with a well for a quantitative method of determining the concentration of radon in the air by measuring the gamma spectra of daughter products lead and bismuth are considered in the paper. A technique is proposed to improve the energy resolution of the detector by using one FEU-173 with the installed reflective ring on the window of the NaI(Tl) crystal instead of using of the three FEU-110. Such modification makes it possible to increase the efficiency of light collection, ultimately increasing the accuracy of the quantitative method.
