8. True or False (use your periodic table/data sheet when appropriate) a. A Geiger counter detects radiation from flashes of light generated by phosphors. b. When the ratio of neutrons to protons is too high or too low an element will exhibit radioactive decay. c. Water surrounding the cylinders of a reactor core slows neutrons down so that the U-235 can capture them more efficiently. d. Bombarding an element with electrons may change an element into another element.
