Analytical approach for <sup>226</sup>Ra, <sup>228</sup>Ra and <sup>210</sup>Pb measurements for environmental monitoring using liquid scintillation spectrometry.
Ra activity concentrations were generally low in most monitored matrices. The results were consistent with literature data reported for uranium mining and milling sites in comparable geological and operational contexts, providing no evidence of URA radiological impact on the environment. This study reinforces the importance of rapid and accurate radionuclide monitoring to ensure environmental safety and regulatory compliance in uranium mining operations.
