This paper reports the thermoluminescence (TL) analysis performed on the oyster shells powder. TL response of 60Co gamma-rays irradiated samples were studied in the range from 80 Gy to 8kGy doses. TL signal of irradiated shell powder was higher as compared to the unirradiated control samples, which allowed to identify the irradiated oysters. Results show that the oyster shell shave good TL properties and can be useful for the identification of irradiated seafood as well as for the evaluation of the treatment dose.
