Polska - Opis:
- In this paper results of natural radioactivity of 40K, 208Tl, 212Pb, 212Bi, 214Pb, 214Bi and 228Ac in common rocks raw materials mined in the Krakow vicinity measured in situ using a portable gamma-ray spectrometry are presented. The study area occupies the SE edge of regional geologic unit called Krakow–Lubliniec Zone. Most Upper Paleozoic rocks exposed in this area like tuff, porphyry, limestone, dolomite, diabase and melaphyre have great economic importance and are used in building and road construction industry. The activity concentrations of 40K for the measured Paleozoic rocks ranged from 53 Bq/kg (Carboniferous limestone) to 3150 Bq/kg (Permian tuff). The activity concentrations associated with 228Ac (232Th) varied from about 7 Bq/kg (Carboniferous limestone) to 56 Bq/kg (Permian tuff), whereas activity concentrations of 226Ra (238U) ranged from 19 Bq/kg (Devonian dolomite) to 43 Bq/kg (Devonian limestone). Besides, the natural radioactivity of the Jurassic limestones (widespread in this region) was measured for comparision with Devonian and Carboniferous limestones.
