The current status of some decay data used in nuclear astrophysics and cosmochronology is presented. The half-life of Se has been evaluated as 3.6(3) × 10 yr. The total energy of non-neutrino radiation released in act of Ar decay has been obtained being 2.709 (16) keV per disintegration. The recommended half-life values of the long-lived radionuclides ( T ≳ 10 yr) of Al, K, Mn, Fe, Rb, Zr, Tc, Pd, I, Cs, Sm, Lu, Hf, Re, Pb, Th, U, U, Pu, and Cm are given based on the evaluations published until 2010.
