A time projection chamber with a selenium double-beta decay source as the central electrode has yielded a lower limit of 1.0 x 10/sup 20/ yr at 68% confidence level for the two-neutrino half-life of /sup 82/Se. This limit is consistent with the results of geochemical measurements, and disagrees with the shorter half-life predictions of nuclear theory. For the neutrinoless mode we find a corresponding lower limit of 7 x 10/sup 21/ yr, also at 68% confidence level.
