As aging nuclear reactors require increased maintenance, and even shut down completely, the strain on their production is being felt far beyond the energy industry: inside oncology and cardiac clinics. But help is on the way. Every year, doctors order as many as 40 million medical imaging scans that require a radioactive isotope called technetium-99m (Tc-99m).

2017-04-15 · Germanium has five naturally occurring isotopes: the stable isotopes are 70 Ge (20.4% abundance), 72 Ge (27.3%), 73 Ge (7.8%), and 74 Ge (36.7%), while 76 Ge (7.8%) is slightly radioactive (half life of 1.55 × 10 21 years) (Klapdor-Kleingrothaus et al., 2001, de Laeter et al., 2000). Het chemisch element germanium (Ge), met een atoommassa van 72,64(1) u, bezit 5 stabiele isotopen: 70 Ge, 72 Ge, 73 Ge, 74 Ge en 76 Ge, waarvan de voorlaatste het meest abundant is (ongeveer 37%). De overige 27 radio-isotopen zijn onstabiel en hebben een relatief korte halveringstijd (de meeste minder dan een seconde ). insight into the evolution of collectivity in light even-even Ge and even-odd As isotopes. Methods: We investigate the low-lying levels and collectivity of the neutron deficient 67As and 66Ge An isotope is a form of a chemical element whose atomic nucleus contains a specific number of neutron' s, info@sgg.ge.
