Radon as a function of ceiling height and occupant behaviour influencing building air dynamics Panel A: Pie chart shows distribution of reporting. Graph shows geometric mean radon (grey bars) and arithmetic mean radon with 95% confidence intervals (black diamonds with bars) by reported number of storeys for the building (as indicated by the cartoon). Panel B: Using the quantile divisions of construction period as in Fig. 4B, data distribution for basement ceiling height. Colours are indicated in legend. Panel C: Using the quantile divisions of construction period as in Fig. 3B, data distribution for main floor (left) and upper floor (right) ceiling height. Colours are indicated in legend. Panels D-F: Pie charts show distribution of reporting. Graph shows geometric mean radon (grey bars) and arithmetic mean radon with 95% confidence intervals (black diamonds with bars) by ceiling height (in feet) reported for either basement/cellar (D), main floor (E) or upper floor (F). Panel G-I: Pie charts show distribution of reporting. G Graph shows geometric mean radon (grey bars) and arithmetic mean radon with 95% confidence intervals (black diamonds with bars) by window opening behaviour reported for either basement/cellar (G), main floor (H) or upper floor (I). ANOVA analysis outcomes are indicated on all graphs. Red dotted lines are a reference point of arithmetic mean radon for cohort.
