Isotopes of tungsten - Wikipedia
网页Naturally occurring tungsten (74 W) consists of five isotopes. Four are considered stable (182 W, 183 W, 184 W, and 186 W) and one is slightly radioactive, 180 W, with an extremely long half-life of 1.8 ± 0.2 exayears (10 18 years). On average, two alpha decays of 180 W occur per gram of natural tungsten per year, so for most practical ...
