The radioactive element radium ({\rm Ra}) decays by a process known as alpha decay, in which the nucleus emits a helium nucleus. (These high-speed helium nuclei were named alpha particles when radioactivity was first discovered, long before the identity of the particles was established.) The reaction is ^{226} {\rm{{\rm Ra}}} \;\to\; ^{222} {\rm{{\rm Rn}}}\; +\; ^4 {\rm{{\rm He},}} where Rn is the element radon. The correctly measured atomic masses of the three atoms are 226.025, 222.017, and 4.003. (The energy released in radioactive decay is what makes nuclear waste "hot.")
