Jeffrey Mahn, Radiation Basics - Energy Deposition in Matter.Ionizing and Non-Ionizing Radiation. Radioactive Decay, the process by which an unstable atomic nucleus becomes more stable by emitting energy in the form of particles or ionizing electromagnetic waves.

Jeffrey Mahn, Nuclear Reactor Safety. All energy forms have upsides and downsides - nuclear energy is no exception. Upside, enormous amount of energy produced by U-235 fission - ~1.5 million times more energy per gram of fuel than hydrocarbon fuels. Downside, energy from decay of radioactive fission products continues to produce heat, which must be removed.

Ramón Cruz has a story about growing up in poverty in the Dominican Republic and deciding to study nuclear engineering in the United States. It is a tremendous success story with many interesting personal details.
