“…The table below shows that the activity concentration of gross alpha and beta are lower than reported studies in Nigeria ( Fasae, 2013 , 2015 ). The tap water results for concentration of gross alpha and beta in this study is higher than similar studies reported in literature ( Damla et al., 2006 ; Darko et al., 2014 ; Saleh et al., 2015 Korkmaz et al., 2016 ). For the ground water: borehole and well water, the activity concentration of gross alpha and beta are higher and lower than reports of Kobya et al.…”

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.

“…Following the procedure of Fernandez et al [66], according to which more than 50% of the annual effective dose is due to the contribution of the radium, some authors [51][52][53][54] estimate the annual effective dose due to the ingestion of radionuclides through drinking water consumption by using the following formula [67]:…”

In the present paper the different ways of assessing the annual effective dose due to ingestion of radionuclides by drinking water consumption were examined and exemplified. On a set of 10 samples the gross alpha activity, the gross beta activity, the concentration of 210Po, 210Pb, 238U, 232Th and, 226Ra were measured. The highest annual effective dose values assessed by relying on the investigated sample set were found by using the rationale according to which all the gross alpha and beta activity is due to the alpha and beta radionuclide, with the highest effective dose coefficient, namely 210Po and 210Pb/228Ra, respectively.

The activity concentrations of 226 Ra, 232 Th and 40 K in 91 soil samples collected from proposed housing sites in Tiruchirappalli district were measured using gamma ray spectrometer, 222 Rn activity using SSNTD technique and ambient absorbed gamma dose employing hand held scintillometer. The mean activity concentrations of 226 Ra, 232 Th and 40 K were found to be 6.5, 61.7 and 379.8 Bq kg -1 , respectively. The mean ambient gamma dose rate was 66.7 nGy h -1 and the mean radon activity 210.8 Bq m -3 . The study identified two stations in which Ra eq levels exceeded the permissible limit (370 Bq kg -1 ).
