“…coming from the fallout from atmospheric nuclear weapons testing and the accidents at nuclear reactors. In consequence of radioactive fallout after the Chernobyl nuclear reactor accident in 1986, 137 Cs radionuclide (T 1/2 ¼ 30.07 y) was widely dispersed in the Turkish environment (Turhan et al, 2012). These radionuclides could present a risk to human health (WHO, 2011).…”

Ra 40 K 137 Cs a b s t r a c t Concentration levels of 226 Ra, 228 Ra, 40 K and 137 Cs were determined in 52 drinking water samples collected from the different supplies in Samsun province to evaluate annual effective dose due to the ingestion of the drinking water samples. The activity concentrations of 226 Ra, 228 Ra and 40 K natural radionuclides in the drinking water samples varied from <27 to 2431 mBq L À1 , <36 to 270 mBq L À1 and <47 to 2880 mBq L À1 respectively. The activity concentrations of the artificial radionuclide 137 Cs in the drinking water samples were lower than minimum detectable activity except in one drinking water sample (DW14)with an associated activity concentration of 2576 mBq L À1 . Contributions of the consumed water samples to annual effective dose from 226 Ra, 228 Ra and 40 K varied from 1.6 to 33.4 mSv y À1 with a mean of 6.1 mSv y À1 , 2.2 to 46.8 mSv y À1 with a mean of 8.6 mSv y À1 , 4.7 to 97.5 mSv y À1 with a mean of 17.9 mSv y À1 for infants, children and adults, respectively. The results showed that all values of the annual effective dose of ingestion of these water samples were below the individual dose criterion of 100 mSv y À1 reported by World Health Organization (WHO).

“…Samples were dried in an oven at about 105°C for 24 h, pulverized, homogenized and sieved through 2 mm mesh. All samples were transferred to containers, weighed, hermetically sealed and stored for 4 weeks to ensure that 238 U and 232 Th attained the secular equilibrium with their short-lived decay products (Turhan et al 2012).…”

“…Distributions of 238 U, 226 Ra, 232 Th and 40 K in soils depend on the radionuclide distribution in rocks from which they originate and on the processes through which the soils are concentrated (Song et al 2012). Soil is the most important source of terrestrial gamma radiation levels, containing trace quantities of terrestrial radionuclides, whose concentrations depend on the local geology of each region in the world (UNSCEAR 2000;Montes et al 2012;Turhan et al 2012).…”

“…The high natural radiation levels commonly are associated with igneous rocks, such as granite, and lower levels commonly with sedimentary rocks [6]. Soil is the most important source of terrestrial gamma radiation levels, containing trace quantities of terrestrial radionuclides, whose concentrations depend on the local geology of each region in the world [7,8]. Measurement of natural radioactivity in rocks and soils is vital in determing and monitoring the amount of change of the natural background activity with time for environmental protection [9].…”

Natural radioactivity is a source of continuous exposure to human beings. It originates from both extraterrestrial sources and radioactive elements in the earth crust. Assessment of radioactive elements in the study area is very important from different point of view especially for human health. The natural radioactivity of soil samples were measured by Gamma spectrometry using 3ʺ×3ʺ NaI (Tl) well detector. Cultivated soil samples were collected from eight regions in El-Minia governorate including; Maghagha, BaniMazar, Mattay, Samallot, El-Minya, Abo Qurqas, Mallawy, and Deir Mawas district. The activity concentration ranged from12.43±0.62 Bq.kg -1 to 30.15±1.51 Bq.kg -1 with average 20.58±1.04 Bq.kg -1 for 226 Ra, 7.27±0.35 Bq.kg -1 to 25.74±1.28 Bq.kg -1 with average14.37±0.75Bq.kg -1 for 232 Th and 149.24±7.45 Bq.kg -1 to 270.94±13.59 Bq.kg -1 with average 210.20±10.55 Bq.kg -1 for 40 K. The measured values are comparable with other worldwide radioactivity and are within the range specified by UNSCEAR 2000 .Also radiological hazard indices were evaluated. All hazard indices are below the permissible limit. Therefore, the radiation hazard and cancer risk are insignificant in the investigated area.
