Storage of Radioactive Fission Product Samples William J. Maeck and James E. Rein, Atomic Energy Division, Phillips Petroleum Co., Idaho Falls, Idaho
It is well known that many ions in very dilute solutions are adsorbed on the surfaces of their containers. To evaluate the storage of dilute fission product solutions the degree of adsorption of M a y cooled and 1-year cooled fission products was measured for two

to develop accurate
methods for the determination of the burnup of nuclear fuels requires the preparation and storage of dilute, standard solutions of fission product nuclides, both stable and radioactive.
