The beta and gamma radiations from the radioactive decay of the isotopes I/sup 134/ and I/sup 133/ have been studied by means of magnetic beta spectrometers and scintillation techniques. A Fermi analysis of the beta-ray spectrum from the decay of I/sup 134/ shows that it is very complex. The maximum energy is found to be 2.35 Mev, and the measured energies of two further components are 1.57 and 1.3 Mev. The energies of the gamma rays following the decay of I/sup 134/ are 0.138, 0.21, 0.42, 0.63, 0.86 (there seem to be two gamma rays with about this energy), periments have been carried out, and the beta disintegration energy (Q/sub BETA /- value) for the decay of I/sup 134/ to Xe/ sup 134/ is estimated as 4.1 Mev. As regards the decay of I/sup 133/, the maximum energy of the beta-ray spectrum is found to be 1.27 Mev. Furthermore, beta components are found having energies of about 0.94 and 0.7 Mev. Gamma rays with the following energies are associated with this decay: 0.35, 0.53, 0.71, 0.87, 1.05, 1.22, and 1.30 Mev. (auth)
