“…One of these research areas is about water, which is one of the basic needs of human. Such studies are widely available in the literature (Fatima et al 2006;Kitto and Kim 2005;Kobya et al 2011;Ehsanpour et al 2014;Mashiatullah et al 2016;Alseroury et al 2018). Chemical analysis [such as pH, conductivity, total dissolved solids (TDS)], have added to the radiological analysis of water by a number of researchers (Lin et al 2003;El Arabi et al 2006;Asaduzzaman et al 2016;Goher et al 2019;Ahmad et al 2019).…”

Water; it is the basic necessity of living things that exist in the world like air and food. An adult person consumes an average of 2 L of water per day by drinking. This consumed water contains a number of radionuclides. For this reason, it is important to determine the effect of these radionuclides on human biological structure. In studies up to now, researchers calculate activity concentrations of radionuclides in drinking water and calculate annual equivalent doses based on these activity concentrations. However, it is always overlooked that this consumption is constant in calculations. This results in the inability of drinking water to fully determine the effect on human health. In this study, a new and comprehensive perspective was introduced in the gamma analysis of drinking water. This viewpoint includes the activity concentration, the annual equivalent dose, lifetime average annual dose, and lifetime cancer risk assessment depending on age groups. Thus, it is aimed that the radionuclides present in water can make more reliable calculations on affecting human health and water cleaning in terms of radiation. The proposed model was applied to some drinking water sources in Gümüşhane. We found out that the obtained values of annual effective dose equivalent in all samples do not exceed the WHO recommended levels. The risk of cumulative cancer at the end of the 70th year of a person using these drinking water sources has been about determined as 1 in 100,000. Positive correlations were obtained between 226 Ra, 232 Th, and 40 K concentrations versus pH. In addition, a negative correlation was obtained 40 K concentration with conductivity.

“…Whereas natural radioactivity comes mainly from long-lived primordial radionuclides that are widespread in the Earth's crust (Alharbi and El-Taher 2013), human activities such as mining and generation of nuclear power add artificial radionuclides to the environment. Human beings are therefore exposed to radiations from sources outside the body and from radionuclides that are ingested through consumption of food and water or inhaled radioactive gases such as radon (Ehsanpour et al 2014;Taskin et al 2009). …”

Activity concentrations of radionuclides in water, soil and tuber crops of a major food-producing area in Ghana were investigated. The average gross alpha and beta activities were 0.021 and 0.094 Bq/L, respectively, and are below the guidelines for drinking water and therefore not expected to pose any significant health risk. The average annual effective dose due to ingestion of radionuclide in water ranged from 20.08 to 53.45 μSv/year. The average activity concentration of (238)U, (232)Th, (40)K and (137)Cs in the soil from different farmlands in the study area was 23.19, 31.10, 143.78 and 2.88 Bq/kg, respectively, which is lower than world averages. The determined absorbed dose rate for the farmlands ranged from 23.63 to 50.51 nGy/year, which is within worldwide range of 18 to 93 nGy/year. The activity concentration of (238)U, (232)Th, (40)K and (137)Cs in cassava ranges from 0.38 to 6.73, 1.82 to 10.32, 17.65 to 41.01 and 0.38 to 1.02 Bq/kg, respectively. Additionally, the activity concentration of (238)U, (232)Th, (40)K and (137)Cs in yam also ranges from 0.47 to 4.89, 0.93 to 5.03, 14.19 to 35.07 and 0.34 to 0.89 Bq/kg, respectively. The average concentration ratio for (238)U, (232)Th and (40)K in yam was 0.12, 0.11 and 0.17, respectively, and in cassava was 0.11, 0.12 and 0.2, respectively. None of the radioactivity is expected to cause significant health problems to human beings.

The radioactivity and radiological hazards associated with sediment samples collected from 13 locations along the Euphrates River as well as 12 associated irrigation wells were tested using a high-purity germanium system (HPGe). The radioactivity of isotopes 226Ra, 232Th, and 40K (Iso-RTK) in these sites exceed the worldwide limits, which makes them a human health risk. The estimated radiological parameters of the Euphrates and the well sediments exceed the radium equivalent (RE), absorbed dose rate (ADR), annual effective dose external (AEDE), internal - external hazards indices (IEHI), , and gamma index (Iy) . The radioactivity of 238U and 232Th (Iso-UT) are constant along the Euphrates River; 40K (Iso-K) concentrations are elevated after the Hindyia barrage and exceed worldwide limits.
