How Nuclear Decay Works

Select an element and decay type above to see the nuclear equation that represents the decay process.

Nuclear Decay Types

Decay Type Particle Emitted Change in Mass Number (A) Change in Atomic Number (Z)
Alpha (α) He-4 nucleus (²⁴He) -4 -2
Beta (β) Electron (e⁻) 0 +1
Gamma (γ) Photon (γ) 0 0
