The interpretation given by the previous authors on the study of the 47- sec activity in iridium can not be proven. For instance, in measurements of the gamma intensity in the energy range from 100 to 450 kev of an Ir sample exposed to slow neutron, the decay of the 47-sec activity can be followed for more than three lifetimes. The study was made with two different measurement arrangements, and equal results were obtained. The gamma spectrum measured is so different from the Rh gamma spectrum that possible Rh impurities are ruled out. (J.S.R.)
