“…Quarries are considered a potential source of increased radioactivity, as stone digging can bring material containing increased radioactive content to the surface ( 3 , 4 ). Research into potentially negative radiological impact of quarries has been focused on the exposure of quarry workers to ionising radiation ( 5 , 6 , 7 , 8 ) and on radioactive content analysis of quarry products ( 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ). However, research of radiological effects of a quarry on its surroundings is not common.…”

Papuk Nature Park, unlike most similar parks and preserves in the world, contains active quarries. Quarries dig stone from the ground, creating dust and exposing deeper, potentially more radioactive layers. Since the forest trails in the Park lead right up to the quarries, we believed it was important to determine the radiological impact of the quarries on the Park environment. We measured ambient dose rate equivalent H*(10) and sampled moss at 26 Park locations along two of four quarries, along the road between them, and near Lake Orahovac, a very popular tourist destination close to the quarries. Moss is a standard bioindicator of exposure to heavy metals, including radionuclides. Using-gamma ray spectrometry we determined the activity concentration of 137Cs and of representative naturally occurring radionuclides – 238U, 226Ra, 210Pb, 232Th, and 40K – in sampled moss. H*(10) at selected locations was similar to the background H*(10) measured continuously all over Croatia. The ranges of measured activity concentrations of 137Cs and naturally occurring radionuclides in moss did not differ significantly from other parts of Croatia and nearby countries.

Sepio lite is a nat u rally oc cur ring clay min eral of sed i men tary or i gin and is a mag ne sium hydrosilicate. Sepio lite has been widely used as an ad di tive raw ma te rial in ce ram ics and cement in dus try, phar ma ceu ti cal, clean ing-de ter gent, pa per, paint, cos metic ag ri cul ture, fer tilizer, etc. In this study, the nat u ral ra dio ac tiv ity lev els, ra don em a na tion co ef fi cients and ra don ex ha la tion rates of 30 sepio lite sam ples col lected from open three sepio lite quar ries (Beylikova, Polath and Sivrihisar) in Cen tral Anatolia re gion of Tur key were de ter mined by us ing a gamma-ray spec trom e try with an HPGe de tec tor. The av er age ab sorbed gamma dose rates di rectly mea sured in Beylikova, Polath and Sivrihisar open three sepio lite quar ries located in Cen tral Anatolia re gion of Tur key were found as 59, 65, and 64 nGyh-1 , re spec tively. The av er age ac tiv ity con cen tra tions of 226 Ra, 232 Th, and 40 K in 30 sepio lite sam ples col lected from those quar ries were found as 38.6, 12.4, and 67.4 Bqkg-1 , re spec tively. The av er age ema na tion co ef fi cient and ex ha la tion rate of ra don of sepio lite sam ples were de ter mined as 22 % and 0.065 Bqkg-1 h-1 , re spec tively.

The radiological hazard of building materials originating from clay, rock and other mineral wastes has attracted more attention because they contain natural radionuclides (226Ra, 232Th, and 40K). The activity concentration of radionuclides in red-clay brick samples obtained from three different brickyards in Shangluo, China waHs measured. Various indexes, including radium equivalent activities, Raeq, external hazard index, Hex, internal hazard index, Hin, indoor air absorbed dose rate, D, and annual effective dose, AED, of the aforementioned radionuclides in the bricks were used to assess the radiation hazard for people. The average activity concentrations of 226Ra, 232Th, and 40K were respectively 34.5 ? 1.9, 62.5 ? 2.1, and 713.7 ? 19.8 Bqkg?1 for the studied red-clay bricks. The Raeq values of the red-clay brick samples varied from 167.0 to 184.7 Bqkg?1, which are lower than the limit of 370 Bqkg?1. Moreover, the activity concentrations of natural radionuclides in unfired brick, clay and coal were also determined and the results were compared with that in the red-clay brick samples. This study shows that the red-clay bricks produced in Shangluo, China can be used safely in construction industries.
