“…48 " 49 Tungsten-178 (21.7day half-life) is the parent of l78 Ta (9.3-minute half-life), and 191 Os (15.3-day half-life) is the parent of 191 Ir m (4.9-second half-life). Currently, 178 W is produced by means of the (p,4n) reaction on 181 Ta by using «40-MeV protons. Thin targets («8 MeV thick) are used and yield a 1.5 mCi/uAhour.…”
