Abstract ： In the recent charts of the nuclides an accepted half-life of 79 Se is only an upper limit, < 6.5 x 104 a. In this letter, A new half-life of 79 Se has been measured to be (1.13 ± 0.17) x 106 a. The number of 79 Se atoms was determined from measured 79 Se /Se ratios with the accelerator mass spectrometry technique and the decay rate of 79 Se was determined by counting the emitted β rays with a liquid scintillation spectrometer.
