Abstract

Three-dimensional transient process of transport of indoor radon has been imitated with numerical differential method

and effects of air pressure

temperature and wind have been quantitatively discussed. The calculation results show that the radon concentration indoors is decreased with the height increasing

and while the air pressure

temperature and wind outside the room change

the pressure differences and radon concentrations indoors will change too

but their phase differences are more than 180°. The experiment proved the measured results consistent with the calculation.
