“…However, all the measured values are within the worldwide average concentrations of these natural radionuclides in drinking water as reported by the United Nations of Scientific Committee of the Effects of Atomic Radiation (UNSCEAR) [1] and other studies [3,4,11]. The levels of radioactivity measured in wells are usually higher than in flowing or well waters because a significant proportion of the radioactivity transported by rivers into wells accumulates there [8].…”

“…Humans are also exposed by contamination of the food chain which occurs as a result of direct deposition of radionuclides on plant leaves, root uptake from contaminated soil, sediment or water [7], and from direct ingestion of contaminated water [8]. To assess these exposures, radioactivity studies have been previously carried out in water samples [8,9].…”

Exposure to radioactive elements or having them through drinking water causes many biological risks.Therefore, it is important to investigate the drinking water especially in regions where people depend on well water for drinking. Concentrations of some radionuclides in some water wells, in Arar city of Saudi Arabia, were measured by using Hyper Pure Germanium (HPGe) Detector. Concentrations of 226 Ra (Radium), 232 Th (Thorium) and 40 K (Potassium) were measured in drinking water of 5 water Selling Stations from different water wells; Alshark, Alsahab, Ghdeer, Katr Elnada and Almohamadia. The radiation hazard indices of water were also calculated. The results showed that the average values of either radionuclides concentration or radiation hazard indices of all water stations under study were in the internationally permissible range. Results therefore emphasize that the investigated wells from which the water was taken are suitable for drinking concerning the measured radionuclides. The work recommends more studies to investigate another radionuclides might be present in the drinking water.

“…Furthermore only 27.5% of the alpha activity is below the contaminant limit of 0.5Bq/L, as set out by WHO, while 72.5% of the alpha activity is above the contaminant limit. Comparing the value of alpha activity found in Sokoto with 0.0063Bq/L obtained in Zaria (Onoja, 2004), and 0.0039Bq/L in Kano (Tajudeen, 2006), that of Sokoto is relatively higher. However, the mean alpha activity obtained in Jos (0.68Bq/L) by Habila (2008) Figure 1 is the distribution of alpha activity and shows few elevated alpha activities.…”

“…Not much work has been done on measurement of radioactivity in water in Nigeria. Onoja (2004) determined gross alpha activity in well water from Zaria area and reported geometric mean values of 6.32Bq/m 3 for alpha activity. Tajudeen (2006) from work in Gwammaja area of Kano metropolitan city reported geometric mean values of 3.99Bq/m 3 for alpha activity.…”

A survey of the gross alpha radioactivity in drinking water from wells and bore holes in Sokoto city was carried out. Forty samples were drawn at random from locally dug wells and bore holes in Sokoto city, Northern Nigeria. The samples were analyzed using the Eurysis system-eight channel gas filled proportional counter. The result shows that the range of alpha activity varied from 0.01 to 6.00Bq/L, with a geometric mean of 0.26Bq/L. Seventy five percent (75%) and 25% of alpha activity were respectively below and above the USEPA contaminant limit of 0.55Bq/L radioactivity in water. Thirty two and half percent (32.5%) and 67.5% of the alpha activity were respectively below and above the contaminant limit of 0.5Bq/L, as set out by WHO. The gross alpha effective dose was 0.068msv/y (WHO range is 0.04-0.1mSv/y).

The increase in economic activities as a result of population surge in Dutsin-Ma has culminated into increase in waste and environmental quality degradation. Hence, this study examined the risk associated with different drinking water sources (dam water (DM), borehole water (BW), Hand dug well water (WW) and tap water (TW)) in Dutsin-Ma, Katsina using concentrations of gross alpha (α) and gross beta (β) activity, and heavy metals cadmium (Cd) and lead (Pb) in the water. A total of Thirty six (36) samples were collected from the study area. Standard methods were deployed for the determination of pH, concentration of gross alpha and gross beta activity and concentrations of Cd and Pb in the water samples were done using chemical fraction method. The results of the pH showed values not within the recommended limits for drinking water quality with exception of 8.30 (WW). Also, the measured activity concentrations of gross alpha in all water samples are below 0.1 Bq/L with few exceptions, while the measured activity concentrations of gross beta in 50% of the total water samples collected are higher than 1.0 Bq/L permissible limit. The mean annual dose equivalent all the water sources is higher than 0.1 mSv recommended dose for radionuclides in water, hence the life cancer risk assessment showed higher values, indicating the water are unsafe for drinking. The results in this study showed that Cd and Pb in all the water fractions (mobile, dissolved, total and particulate) are above the WHO recommended limit of 0.003 and 0.01 mg/L in drinking water. Similarly, the hazard index (HI) for the water samples are greater than one (1), hence, a possible concern for potential carcinogenic effect for consumer of the water sources.
