Ionizing radiation intensity data and estimation of equivalent absorbed doses from solid and liquid samples from prospecting shale gas and oil at select sites in Pomerania are presented. Naturally occurring radioactive materials (NORM) are associated with geological formations or fluids and can be enhanced during oil and gas production. They appear in e.g. drilling cuttings, flow-back water, produced water, scale, and sludge. In this study only gamma rays were detected and their intensity was comparable to the background radiation, which is 20.0±4.6 [min-1]. The highest value of 27.3 [min-1] was detected in solid residue from evaporated flow-back fluid after hydraulic fracturing. The equivalent absorbed dose from this sample was ~ 2 Sv/a, which is lower than the global average dose from 2.4 Sv/a background radiation. In this regard, workers and others in the vicinity of drilling well sites will not be exposed to external or internal ionizing radiation.
