Optical trapping of selected species of radioactive atoms has great potential in precision measurements for testing fundamental physics such as the electric dipole moment, atomic parity nonconservation, and parity-violating {beta}-decay correlation coefficients. We report on the trapping of 10{sup 4} radioactive {sup 82}Rb atoms (t{sub 1/2}=75 s) with a trap lifetime of {approx}55 s in an optical dipole trap. Transfer efficiency from the magneto-optical trap is {approx}14%. We further report evidence of spontaneous spin polarization of the atoms in optical dipole trap loading. These advancements are an important step toward a new generation of precision nuclear-spin-{beta}-emission direction correlation measurements with polarized {sup 82}Rb atoms.
