The Commission of the European Communities organised interlaboratory test measurements on alpha-contaminated waste. The intention was to compare methods and tools used in different laboratories and to determine the plutonium content of real waste drums. The exercise involved measuring drums in which sources of known Pu-content and composition were placed in defined positions. Furthermore, a total of nine sealed drums with unknown Pu-content and composition were measured and the Pu-content determined. The measurements show that more work has to be done. The stated uncertainties are not always realistic. A good calibration is necessary, taking into account matrix and source position effects. The correction for matrix and source position effects proves to be very important and has to be investigated further.
