Alpha Decay of Thorium-232

232Th → 228Ra + 4He

概述

Thorium-232 alpha decays to radium-228 with a half-life of 14.05 billion years, longer than the age of the universe. Thorium is about 3-4 times more abundant than uranium in Earth's crust. The thorium fuel cycle is an alternative to uranium for nuclear energy with proliferation-resistance advantages.
