222Rn in groundwater in Nigeria: a survey.
222Rn in groundwater was measured in wells of different rock types in Nigeria by direct gamma counting. Concentrations ranged between 1.7 +/- 0.1 and 161.6 +/- 2.4 Bq L-1, with only slight variations (maximum 2.1 sigma from the mean) in a year in a typical well.
