ゲルマニウムの同位体
1. Isotopes of germaniumGermanium (Ge) has five naturally occurring isotopes, Ge, Ge, Ge, Ge, and Ge. Of these, Ge is very slightly radioactive, decaying by double beta decay with a half-life of 1.78 × 10 years (130 million million times the age of the universe), giving it the distinction of being the nuclide with the longest directly measured half-life (tellurium-128 has a half-life > 1000 times longer, but it has been indirectly measured by decay products in ancient rocks).
