Radon

Measurements of indoor and outdoor radon concentrations have been made at an experimental facility supported by the US Department of Energy. The main goal is to understand how vegetation near a structure can influence indoor radon concentrations.

Daily averaged radon concentrations measured 1 m above the ground for the calender year 1994. Also shown is the daily averaged barometric pressure.

 

Distribution of daily averaged radon concentrations measured 1 m above the ground from 1993 - 1995.

 

Hourly averaged outdoor radon concentration measured from 1 July 1994 to 31 Dec 1994. This illustrates the diurnal pattern of outdoor radon at 1 m above the ground.
