초록

A total of 138 samples corresponding to 24 different types of imported processed food items, distributed between January and November 2019, were collected in order to test their radioactive contamination levels. The radioactivity of 131I, 134Cs, and 137Cs was measured via gamma spectrometry using an HPGe detector. Radiation levels of 131I and 134Cs higher than the minimum detectable activity value were not detected in any of the samples. However, in 20 samples, radiation levels of 137Cs, ranging between 0.86 and 79.28 Bq/kg, were detected. The food items tested included cashew nuts, hazelnuts, noni juice, Neungi mushroom, pine pollen, and aronia powder; the food items had been imported from India, Vietnam, Turkey, the United States of America, Russia, China, and Poland. Among these food items, the radiation level corresponding to 137Cs in Neungi mushroom, imported from Russia, was the highest, with a concentration of 79.28 Bq/kg. In this study, the radiation concentrations of all the collected food items were below the maximum permitted level of 100 Bq/kg. In the future, it may be necessary to monitor various food items based on consumption trends in order to alleviate consumer anxiety regarding radioactivity in food.
