types of radioactive decay
Types of Radioactive Decay
  • alpha production (a, He): helium nucleus
  • beta production (b, e):
  • gamma ray production (g):
nuclear stability
NuclearStability

Decay will occur in such a way as to return a nucleus to the band (line) of stability.

alpha radiation
Alpha Radiation

Alpha decay is limited to VERY large, nuclei such as those in heavy metals.

beta radiation
Beta Radiation

Beta decay converts a neutron into a proton.

fission
Fission

Fission - Splitting a heavy nucleus into two nuclei with smaller mass numbers.

deuterium tritium fusion reaction
Deuterium – Tritium Fusion Reaction

Fusion - Combining two light nuclei to form a heavier, more stable nucleus.

energy and mass
Energy and Mass

Nuclear changes occur with small but measurable losses of mass. The lost mass is called the mass defect, and is converted to energy according to Einstein’s equation:

DE = Dmc2

Dm = mass defect

DE = change in energy

c = speed of light

Because c2 is so large, even small amounts of mass are converted to enormous amount of energy.
