2. Nuclear fission is the source of energy for nuclear power and weapons. (True) (False)

3. Nuclear energy arises because the mass of fission products is greater than the mass of the fissionable starting material such as Uranium 235. (True) (False)

4. A rapid, chain reaction can occur in nuclear fission because each neutron that impacts a Uranium 235 or Plutonium 239 creates more than one neutron.  As more neutrons are produced and react, an explosive release of energy can take place.  (True) (False).

5. Gamma rays and beta rays are light and so they fly off and are not damaging.  It is the heavier neutrons and alpha particles that cause damage to living things.  (True) (False).
