Radiation. The emission of energetic particles The study of it and the processes that produce it is called nuclear chemistry. Unlike the chemistry we have studied to this point, nuclear chemistry often results in one element changing into another one. Tragedy. April 26, 1986, 1:24 am

Radiation. Basics of Radiation. Energy that comes from a source and travels through material or space. Light, heat and sound are types of radiation. The kind of radiation discussed in this presentation is called ionizing radiation because it can produce charged particles (ions) in matter.

Radiation. Alpha, Beta, Gamma. Parts of a Nuclear Reactor. Nuclear Fission. Fission means “to split apart” just like the word fissure is a crack or split in a surface. Fission occurs when free neutrons are fired at a nucleus and it splits apart, giving off a tremendous amount of energy.
