Web30 dec. 2014 · Dec 30, 2014 I believe you were referring to the beta decay of Thallium-207 ( Tl-207 ), not Ti-207, since the latter, Titanium, has an atomic mass of 47.89u, not even close to 207u. So, Tl-207 is one of the 37 isotopes of Thallium and has a half-life of 4.77 minutes, the longest half-life of naturally-occuring radioisotopes. Web27 jan. 2024 · THE SCIENCE. A cyclotron is a type of particle accelerator which repeatedly propels a beam of charged particles (protons) in a circular path. Medical radioisotopes are made from non-radioactive materials (stable isotopes) which are bombarded by these protons. When the proton beam interacts with the stable isotopes, a nuclear reaction …
