Tungsten Isotopes are used in several applications. W-180 is used for the production of the therapeutic radioisotope W-181. W-186 is used for the production of W-188 which is used in so-called Tungsten-Rhenium generators. The W-188 daughter Re-188 is “milked” from there generators and used as a therapeutic radioisotope. W-184 has been used to study the elastic and inelastic scattering of heavy ions. |
