The impact factors on dose control were systematically analyzed as there are some dose control prob-lems in the γ irradiation process with the single plate source in dynamic gamma irradiation plant. The establishment of irradiation dose measurement system and the improvement of irradiation facility were carried out for the dose control technology. Through lots of dose tests and statistical analysis, dose control ability in the irradiation was assessed. The result show that the irradiation stability and dose nonuniformity can be improved easily meanwhile the quality of irra-diation processing becomes better. It may give some good suggestion to irradiation processing production.Cited
