Nuclear Weapons Create Their Own Security Codes With Radiation

Nuclear weapons are a paradox. No one in their right mind wants to use one, but if they're to act as a deterrent, they need to be accessible. The trick is to make sure that access is only available to those with the proper authority. To prevent a real life General Jack D Ripper from starting World War III, Livermore National Laboratory's (LLNL) Defense Technologies Division is developing a system that uses a nuclear weapon's own radiation to protect itself from tampering.
