Gamma irradiation was applied to dried pollack to improve its microbiological quality and evaluate quality stability of irradiated samples. Thermoluminescence (TL) properties of minerals separated from irradiated samples were measured for possible use in identifying irradiation treatment. Dried pollack was packaged in commercial unit (PVC film, 0.06 mm thickness) and stored at 15±1℃ for 6 months. Samples showed over 10∨4 CFU/g in total aerobic bacteria or yeasts and molds, which increased during storage, reaching 10∨6-10∨7 CFU/g at 3rd month of storage.
