← ScienceWhich consequence during strontium-90 beta decay enables radiocarbon dating?
A)Neutron capture rate declines negligibly
B)Carbon-14 abundance changes predictably✓
C)Electron tunneling emits alpha particles
D)Radioactive equilibrium instantly re-establishes
💡 Explanation
Beta decay from strontium changes the neutron-proton ratio, which via the carbon cycle impacts the abundance of radioactive C-14 levels. Therefore, radiocarbon dating methods become inaccurate rather than staying constant because the atmospheric baseline shifts.
