An international intercomparison of internal proportional gas counting
of Kr-85 and H-3 has been carried out under the auspices of EUROMET,
a European Collaboration in Measurement Standards. A sample of Kr-85 m
ixed with inactive krypton gas was measured at three laboratories and
a sample of H-3 mixed with nitrogen gas was measured at four laborator
ies. In each case agreement was achieved within the stated uncertainti
es. The experimental techniques employed at each of the participating
laboratories are described and a statement of the results and conclusi
ons is provided.
