Figure 22: Time run of: (a) total number concentration of general aerosol particles ( 𝐶 N g e n ( t o t ) ) and geometric mean values of their diameters ( 𝑑 G M ), (b) activity concentration of radon ( 𝐶 A R n ) and equilibrium equivalent activity concentration of radon decay products ( 𝐶 A R n D P ), (c) number fraction of particles smaller than 10 nm ( 𝑥 g e n (<10)) and smaller than 20 nm ( 𝑥 g e n (<20)), (d) activity fraction of the unattached RnDP ( 𝑓 u n ) and number fraction of the unattached RnDP ( 𝑥 u n ), (e) activity concentrations of the unattached RnDP atoms ( 𝐶 A u n 2 1 8 P o , 𝐶 A u n 2 1 4 P b , and 𝐶 A u n 2 1 4 B i ), (f) activity concentrations of the attached RnDP atoms ( 𝐶 A a t t 2 1 8 P o , 𝐶 A a t t 2 1 4 P b , and 𝐶 A a t t 2 1 4 B i ), (g) number concentrations of the unattached RnDP atoms ( 𝐶 N u n 2 1 8 P o , 𝐶 N u n 2 1 4 P b , and 𝐶 N u n 2 1 4 B i ), and (h) number concentrations of the attached RnDP atoms ( 𝐶 N a t t 2 1 8 P o , 𝐶 N a t t 2 1 4 P b , and 𝐶 N a t t 2 1 4 B i ), in indoor air on January 6 (boiling water in the kitchen from 20:00 to 20:12).
