Studies of the radioactivity of Amang effluent

Total integrated γ counts of the spectrum and γ counts corresponding to the peaks 295 keV and 352 keV of 214Pb, 609 keV and 1120 keV of 214Bi, 511 keV, 583 keV and 860 keV of 208Tl, 911 keV of 228Ac emanating from amang effluent samples were recorded using a GeLi detector. Results have shown the principal source of radioactivity to be the 232Th series. The solubility of thorium oxide in increasingly acidic aqueous solutions has been shown to produce elevated levels of γ activity.
