Summary After many interlaboratory trials, several EPR methods for the detection of irradiated foods are being prepared as standard protocols. The works of Goodman et al. (1994) and Raffi et al. (1992) present conflicting general recommendations for optimum parameter sets in the EPR protocols. Here we demonstrate the shortcomings of recommending general parameter sets for the varying types of food samples and the different spectrometer configurations employed to examine them.
