Article Synopsis
- The study focused on measuring levels of plutonium and strontium isotopes in domestic seafood in Korea due to public concerns about radionuclide contamination.
- Regulatory authorities typically analyze other radionuclides like cesium, but there was a need to investigate plutonium and strontium specifically.
- Ultimately, 40 seafood samples were collected and tested, with results showing no detectable levels of plutonium or strontium, reinforcing seafood safety for consumers.

As a national project, obtaining information on the amount of heavy metal exposure of individuals through food intake is an important basic parameter for risk assessment. This study was conducted to evaluate dietary exposure levels and various risks from mercury (Hg) in Korean foods. In total, 342 samples comprising 114 food items were collected and then cooked prior to analysis.
