Radon mapping in Belgium using local estimates of the lognormal radon distributions in regularly spaced grid points

    Research outputpeer-review


    In order to estimate the local probability that a dwelling will show an indoor radon concentration above a chosen threshold, one should be able to make an estimate of the local distribution of indoor radon values. We tried to make estimates of local radon distributions for the province of Limburg in Belgium, by interpolating a regularly spaced grid of radon values starting from the original set of irregularly spaced radon measurements. In each node of the grid, the local radon distribution was estimated using the radon value in the node and in its 24 nearest neighbours, that is the first and the second neighbouring rows and columns around the node. We investigated the influence of the distance range encompassed by these 25 points, on the resulting radon probability maps. It appears that in order to obtain reliable radon probability maps, this range should ideally be of the order of the average distance between initial radon measurement points.
