Abstract

|
|
|
Samples of fishery products were tested for radioactivity by using the intake frequency data from Korea Health Statistics. The radioactivity of 40K, 137Cs, 134Cs, and 131I was analyzed using gamma spectrometry with a simplified sample pre-treatment procedure. The radioactivity range for 40K was 21.9-3050 Bq/kg, whereas the radioactivities of 137Cs, 134Cs, and 131I were under minimum detectable activity which were in the range of 0.140-1.97, 0.0900-1.89 and 0.124-1.94 Bq/ kg, respectively, for the three species. The results suggest that the Fukushima accident did not have a significant impact on domestic fishery products, which were analyzed during the period from 2013 to 2015. Additionally, there seemed to be no significant impact of additional exposure dose by the analyzed radionuclides.
