Summary

A technique for studying short-lived radio-activities is described. It is suitable for half-lives in the range from a second to several minutes. The activity is induced at one point in the sample spread over a moving, endless conveyor belt and is studied at another point. The equilibrium counting rate then depends on the speed of the belt. The activity of 22 sec. Ag110 and that of 2·3 min. Ag108 have been studied. The maximum energies of beta-ray groups were determined from absorption curves. Gamma-ray energies were obtained with a scintillation spectrometer. It is shown that in favourable cases, when two short-lived activities are present, the shorter-lived one can be filtered out by adjusting the speed of the belt.

The authors believe that the technique can easily be adapted to an experiment where irradiation is obtained by means of a reactor and can be of great value when making detailed investigation of radiations from short-lived isotopes.
