“…Apart from the non-detectable concentrations of 40 K in the Awa7, Awa25, and Awa34 samples, the concentration of the radionuclide is higher in each of the samples than the corresponding concentrations of the radionuclides 226 Ra and 228 Ra. This trend has always been observed generally in various studies conducted for the radioactivity in surface soil samples ( 38 , 39 ), in building materials ( 40 – 42 ), and in drilled and dug well waters ( 22 , 24 , 43 , 44 ), all from the region to which the study area belong. As a primordial isotope with a half-life of 1.28 × 10 9 years, 40 K occurs in abundance in all terrestrial media and its activity depends greatly on the local geology in any location like other radionuclides.…”

Radiological investigation of 35 brands of most popularly used sachet drinking water in Ondo state, Nigeria has been carried out using a spectrometric method for evaluating the concomitant health risks to the members of the public. Activity concentrations of the investigated radionuclides 40K, 226R, and 228Ra were in the range from 16.35 ± 4.10 to 199.94 ± 38.40 Bq L−1 with an arithmetic mean (AM) of 66.22 ± 54.99 Bq L−1, from 1.35± 0.79 to 17.06 ± 5.13 Bq L−1 with an AM of 6.88 ± 3.66 Bq L−1, and from 1.95 ± 0.08 to 17.22 ± 3.87 Bq L−1 with an AM of 9.49 ± 4.98 Bq L−1, respectively. The determined annual effective doses and the corresponding excess lifetime cancer risks due to 226Ra and 228Ra were found to exceed the acceptable limits of 0.1 mSv y−1 and 10−3 respectively, as suggested by the World Health Organization (WHO). This implies a non-negligible carcinogenic health hazard due to the intake of the surveyed drinking water, especially for the lactating babies (0–1) y and teenagers (12–17) y. The data from this research may form an invaluable component of radiometric values of the database in Nigeria, as well as the world for setting up guidelines and control policies for the use of sachet water.
