The average concentrations in two experimental areas, called A6 and A5, were measured to be 53.4$\\pm$0.2 Bq/m3 and 33.5$\\pm$0.1 Bq/m3, respectively. The lower value in the A5 area reflects the presence of better temperature control and ventilation. The radon concentrations sampled within the two A5 experimental rooms' air are found to be correlated to the local surface temperature outside of the rooms, with correlation coefficients r = 0.22 and r = 0.70.
