Use of a model data set to test methods for mapping radon potential.
It is difficult to test the accuracy of mapping methods using real measurement data of radon levels in houses, as different methods produce different maps, and there is no standard to compare them with. A model data set, Linevar, was therefore constructed, having features which allow the accuracies of different mapping methods to be compared. Data for Linevar were generated such that they had a geometric mean that varied across the map in a pattern of stripes of higher and lower radon potential. with widths of 1, 2, 4, and 8 km over an area 100 km square. The geometric standard deviation was kept at a constant value. Data were generated at densities varying from 1 to 100 results per 1 km grid square in different parts of the map. The data set was used to develop a mapping method that shows as much detail as possible without generatin, artefacts.
