Abstract

To detect γ-ray irradiation traces for foods, thermal chemiluminescence spectra of food packages were measured with a multichannel Fourier-transform chemiluminescence(FT-CL) spectrometer, where the irradiation dose was chosen in the range between 10Gy and 10kGy. It was found that the highest sensitivity for the γ-ray irradiation was ?? 10Gy dose, which was much better than that of the ESR method. In addition, the γ-ray irradiation traces of the samples were detectable after 14 months. It was confirmed that the FT-CL is useful as a screening method to detect γ-ray irradiation traces for foods.
