Seeds and cereal grains can be treated with low energy (<300 keV) or high energy (1–10 MeV) electrons for decontamination of phytopathogenic and spoilage organisms. In this preliminary study, maize samples were treated with low energy electrons of 125 keV or high energy electrons of 10 MeV. To identify the electron treatment different detection methods were(More)
