Determine whether each statement about electromagnetic radiation is true or false. The term “radiation” includes all radio waves and visible light. Visible light has enough energy to remove electrons from atoms and molecules. Alpha-particles are the most dangerous to humans if they are swallowed. Beta-particles are unable to travel through human skin. Gamma rays are approximately 1 pm long. Gamma-emission does not alter cither the mass or identity of an atomic nucleus. All nuclear decay processes are governed by first order kinetics. Heating a sample of radioactive material will help to increase the rate of decay.
