 "He removed the tritium contained in a waxy substance inside the sights, and then, using a variety of pseudonyms, returned the sights to the store or manufacturer for repair—each time collecting another tiny quantity of tritium. ​ When he had enough, David smeared the waxy substance over the beryllium strip and targeted the gun at uranium powder. He carefully monitored the results with his Geiger counter over several weeks, and it appeared that the powder was growing more radioactive by the day." "He removed the tritium contained in a waxy substance inside the sights, and then, using a variety of pseudonyms, returned the sights to the store or manufacturer for repair—each time collecting another tiny quantity of tritium. ​ When he had enough, David smeared the waxy substance over the beryllium strip and targeted the gun at uranium powder.

 +"Now seventeen, David hit on the idea of building a model breeder reactor. He knew that without a critical pile of at least thirty pounds of enriched uranium he had no chance of initiating a sustained chain reaction, but he was determined to get as far as he could...David took the highly radioactive radium and americium out of their respective lead casings and, after another round of filing and pulverizing,​ mixed those isotopes with beryllium and aluminum shavings, all of which he wrapped in aluminum foil. What were once the neutron sources for his guns became a makeshift “core” for his reactor. He surrounded this radioactive ball with a “blanket” composed of tiny foil-wrapped cubes of thorium ash and uranium powder, which were stacked in an alternating pattern with carbon cubes and tenuously held together with duct tape."

 +"“It was radioactive as heck,” he says. “The level of radiation after a few weeks was far greater than it was at the time of assembly. I know I transformed some radioactive materials. Even though there was no critical pile, I know that some of the reactions that go on in a breeder reactor went on to a minute extent.”"​

 +"​warned him that real reactors use control rods to regulate nuclear reactions. Miller recommended cobalt, which absorbs neutrons but does not itself become fissionable...David purchased a set of cobalt drill bits at a local hardware store and inserted them between the thorium and uranium cubes. But the cobalt wasn’t sufficient. When his Geiger counter began picking up radiation five doors down from his mom’s house, David decided that he had “too much radioactive stuff in one place” and began to disassemble the reactor. He placed the thorium pellets in a shoebox that he hid in his mother’s house, left the radium and americium in the shed, and packed most of the rest of his equipment into the trunk of the Pontiac 6000."
