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.
Ionizing radiation is energy that is carried by subatomic particles and photons capable of causing atoms to lose electrons and become ions. 1  For example, this radiation is given off by the radioactive decay of unstable atoms, X-ray machines, particle accelerators, and nuclear reactions such as fission.
