The ESR signal of black sesame, soybean, peanut irradiated with 0?9 kGy absorbed dose was determined and the characteristics and intensity were different. The relationship between signal intensity and absorbed doses was also investigated .The results showed that the ESR spectra of irradiated samples inhibited obvious variation compared to those un-irradiated. The dose-response curves of the samples exposed to gamma rays could be described well by binomial function. Besides, the ESR signal intensity was related to the species of samples. This study may be a method for detection of irradiated oilseed by ESR.
