Studies in humans, cats and dogs have all substantiated positive weight loss results when adding fiber to calorie restricted programs. Canned green beans provide extra fiber, are generally a hit with dogs, and only contain about 50 calories per can. Human subjects report a greater sense of satiation or âfullnessâ with the fiber addition and tend to eat less if given free access to food.
1 Excitation occurs when the radiation excites the motion of the atoms or molecules, or excites an electron from an occupied orbital into an empty, higher-energy orbital.  Ionization occurs when the radiation carries enough energy to remove an electron from an atom or molecule.
Radioactivity is the term used to describe the natural process by which some atoms spontaneously disintegrate, emitting both particles and energy as they transform into different, more stable atoms. This process, also called radioactive decay, occurs because unstable isotopes tend to transform into a more stable state.
