The spatial distribution of Radon-222 in Soil: SaTScan and Geographic Information System

\nThis study identifies clustering and hotspot radon concentrations in the city of Najaf's soil samples with the RAD-7 detector. The radon concentration varied from 0.16 kBq /m3 to 10.04 kBq /m3 with an average value of 3.69 ±2.26 Bq/m3 were a normal level according to the Sweden Criteria. Radon concentrations were mapped using a geographic information system approach, and a clustered distribution was found using local spatial autocorrelation analysis. Three regions were found to be H-H clusters (hot spots) based on the Moran index study of spatial autocorrelation within local regions, whereas five regions were found to be L-L clusters (cold spots). Three important spatial clusters were found using a spatial scan analysis.\n
