Evaluation of the activity of gamma-emitting natural radionuclides in seafood and estimation of the annual effective dose for different age groups in KSA

Research output: Contribution to journalArticleResearchpeer-review

Abstract

Twenty-six brands of canned tuna and sardines imported from several countries in Southeast Asia to consume in the KSA. All samples were prepared and analyzed by using a High Pure Germanium Detector of 40% efficiency. Natural radionuclides 40K, 238U (226Ra) and 232Th(228Ra) series were observed with a varying range in all analyzed samples. The values found to be 192.3 ± 14.6, 1.5 ± 0.8 and 1.0 ± 0.6 Bq kg-1 for canned tuna and 219.8 ± 15.8, 0.37 ± 0.3 and 1.2 ± 0.3 Bq kg-1 for canned sardines, respectively. Cesium-137 was not detected at any sample. The comparison between the average activity concentrations of 40K, 238U(226Ra) and 232Th(228Ra) in both canned tuna and sardines was performed and discussed. The dose assessment due to consume/ingestion of seafood was calculated and observed that the calculated committed effective dose is within the global internal dose (290 μSv/y).
