A study of radon‐222 in ground water in Northern Ireland has revealed a range of concentrations from 5.8Bql −1 to 36.6Bql −1 (158pCil −1 (158pCil −1 to 989 pCil −1 ). Radon‐222 was measured using a portable degassing system with scintillation cells and a portable radiation detector. Twenty‐six samples were taken within the Sherwood Sandstone Aquifer underlying Belfast and Newtownards, County Down.; All samples collected were below the National Radiological Protection Board (NRPB) suggested limit of 100Bql −1 . Several hypotheses were considered for the distribution pattern in the sandstone, the most probable being the presence of faults and lithological differences.
