Determination of 226Ra in TENORM Sample Considering Radon Leakage Correction

Background: Phosphogypsum is material produced as a byproduct in fertilizer industry and generally used for building materials. This may contain enhanced radium-226 (226Ra) activity concentration compared to its natural that lead indoor radon accumulation. Therefore, an accurate measurement method proposed this study determine 226Ra phosphogypsum sample, considering the potential leakage from sample container.Materials Methods: The International Atomic Energy Agency (IAEA) reference was study. High-purity germanium (HPGe) gamma spectrometry measure of decay products, i.e., 214Bi 214Pb. Marinelli beakers sealed with three different sealing methods were containers. Due beaker (MB), correction resulted needed. leaked fraction escaped container calculated added measured values.Results Discussion: Total determined by summing up method. results obtained peak 723.4 ± 4.0 Bq· kg-1 MB1 719.2 3.5 MB2 showed about 5% discrepancy certified activity. Besides, 214Pb 741.9 3.6 740.1 3.4 2% difference activity.Conclusion: show insignificant values provided improvement spectrometry. measuring TENORM (technologically naturally occurring radioactive material) using can be concluded convenient easily conducted simple calculation.
