Abstract
Radon 222 was measured continuously in a groundwater system in Nigeria for one year by γ-spectroscopy. The mean Rn concentration for a particular month is 15,1 Bq/l with a standard deviation of 1.0 Bq/l while the mean for the whole year is 14.8 Bq/l with a standard deviation of 1.4 Bq/l. All the values for the year lie essentially within ±δ of the mean. Rainfall appears to be the only major factor causing variations.
