Volume 2 May 1954 Number 9 ATOMIC BATTERY TUESDAY, MAY 11 "For more than 40 years, science has searched for a practical way of convert- ing radiation from the atom's nucleus to . Though our research is far from completed, successful operation of RCA's Atomic Battery in our labora- tories represents a major breakthrough toward that goal." With these words General Sarnoff announced the success of an atomic bat- tery in which the Beta particles from 50 millicuries of radioactive - 90 are used to bombard a semiconductor p-n junction, releasing 200,000 for each received—enough to operate a transister.
