How radionuclides decay and how they are made — the physics behind the pharmacy, pitched for R2 boards.
1 Radioactive decay
Toggle a decay mode, study an example clinical nuclide, then trigger a decay event and watch the particle leave the nucleus. Side panel stays at R2 / ABR depth — mechanisms and the numbers that matter, not derivations.
