Data on the concentration of radon in ground water were compiled from the literature. From this compilation and data collected for this study, the means, medians, modes, standard deviations, coefficients of skewness and histograms have been calculated. The histograms were compared with the normal and lognormal distribution functions using chi‐square test values for goodness of fit. Based on this, the concentrations were found to be lognormally distributed in all cases studied but one. The measured medians and modes were compared with their theoretical counterparts assuming either normality or lognormality, and lognormality was found once more.
