# Atomic Alchemy

Atomic Alchemy is building a bank of reactors to produce the nuclear material that goes into nuclear medicine. Radiopharmaceuticals are vitally important in biological tracers, diagnostic imaging, and cancer treatments. Currently, the world's supply of Molybdenum-99, the cornerstone of 80% of all nuclear medicine procedures, is sourced from just six government-run, scientific research reactors abroad. Five of these reactors are 45-65 years old and are quickly coming to the end of their operation
