Intercomparison exercise on the determination of plutonium in biological material.
This paper gives the results of an intercomparison exercise on the determination of plutonium-238 in urine. The urine, containing metabolised plutonium, was analysed by 6 laboratories in the United Kingdom and 5 in France. Three solutions were provided, a high and low level solution and a blank solution comprising the diluent urine. Several different methods were used by the various laboratories and the results showed good agreement between them.
