The radiations of 2.33-hr ${\mathrm{I}}^{132}$ have been investigated with magnetic lens and scintillation spectrometers. Beta rays of 2.12 (18 percent), 1.53 (24 percent), 1.16 (23 percent), and 0.9 (20 percent) Mev have been identified. Gamma rays of 0.528 (25 percent), 0.624 (6 percent), 0.673 (100 percent), 0.777 (75 percent), 0.96 (20 percent), 1.16 (8 percent), 1.40 (11 percent), 1.96 (5 percent), and 2.2 (2 percent) Mev have been observed, and their coincidences are tabulated. A possible decay scheme is proposed which is consistent with the experimental data.
