Title

Geochemically Measured Half-Lives of 82Se and 130Te

Abstract

We have repeated the measurement of radiogenic 82Kr and 130Xe in the mineral kitkaite, NiTeSe, and obtained half-life values of (1.2 ± 0.1) × 1020y for 82Se and (7.5 ± 0.3) × 1020y for 130Te based on the parent/daughter ratios in the kitkaite and the xenon retention age of associated uraninite. The mineralization age of the kitkaite is used to set upper limits of T1 2 82 ≤ 2 × 1020y and T1 2 130 ≤ 12.5 × 1020y.
