Verification of declared content in the transport of radioactive material

The illicit trafficking of nuclear and other radioactive materials during legal transport (in the presence of a licence and other certified documents) across borders by substituting the quantity or quality of the declared materials poses a serious problem for customs authorities at border checkpoints. To prevent such cases of illicit trafficking, the parameters of the declared nuclear or other radioactive materials must be compared to the actual measured parameters of the material being transported. The paper describes procedures and methods for carrying out a customs control of nuclear and other radioactive materials during their legal transport across borders. (author)
