Abstract: The content of ~(237)Np in 13 kinds of foodstuffs is determined by a combined analysis method.Frist, the ~(237)Np in the foodstuff dust is radiochemically separated and enriched, then the α-sourceof ~(237)Np is prepared by electrodeposition and the α-particle is detected using a Au(Si) detector.The analytical results show that the content of ~(237)Np in such foodstuffs is in range of 10~(-4)--10~(-3)Bq·kg~(-1).
