Abstract: This article presents a methodology based on two complementary approaches, thus allowing a selection of maximal concentration in foodstuffs for determining appropriate countermeasures. The first approach is based on a minimal and maximal per capita intervention level and takes into account the annual intake of each product. The second one is based on a cost‐benefit analysis, comparing the advantages of a countermeasure concerning those products presenting a contamination higher than a given maximal concentration (in terms of reduction of cost of the detriment associated with the risk), with its drawbacks (in terms of cost of the products) in order to select the “ALARA” maximal concentration. This second approach is used as a complement to the first one. The results obtained through these two approaches are given for four products (milk, meat, fresh vegetables, and corn) and two nuclides (Cs‐137 and I‐131). These are presented for various scenarios: one or various products contaminated by one or various radionuclides. It is concluded that these two approaches are complementary, the first one being related to individual risk and the second to collective risk. Therefore, these approaches are both of interest in the context of the elaboration of modalities for the radiological control of foodstuffs following an accidental release and both methods may be useful for determining appropriate countermeasures.
