Table 2
Minimum and maximum values, geometric means, and geometric standard deviations for the total number concentration of general aerosol ((tot)), geometric mean of number size distribution of general aerosol (), number fractions of particles smaller than 10โnm ((<10)) and smaller than 20โnm ((<20)), radon activity concentration (), equilibrium equivalent concentration of radon short-lived decay products (), equilibrium factor between radon and radon short-lived decay products (), activity fraction of the unattached radon short-lived decay products (), and number fraction of the unattached radon short-lived decay products (), for the entire period of measurements indoors (28โ31 October, 21-22 November, and 5-6 January), only when the door and window were closed and without any human activity.
