Bismuth try much time named low-radioactive, however, 209Bi (their longest existed isotope) in reality decays having a 1 / 2 lifetime of dos.01×1019 decades or around a very important factor 10 slower than simply 180W. However, on account of naturally occurring bismuth being 100percent 209Bi, their specific activity is largely more than regarding sheer tungsten during the step 3 milli-becquerel for each kg.
