An international exercise, registered as EUROMET project n° 907, was launched to measure both the activity of a solution of 124Sb and the photon emission intensities of its decay. The same solution was sent by LNE-LNHB to eight participating laboratories. Activity measurements were performed using the 4 pi beta-gamma coincidence counting technique, CIEMAT/NIST liquid scintillation counting, a well-type ionization chamber and a well-type crystal detector. The results are compared and possible explanations for discrepancies are sought. Six participants sent results for photon emission intensities both in absolute and in relative values. From these results and including previous published values a consistent decay scheme was worked out, proving that problems in activity measurements are not due to decay scheme data.
