...uranium nucleus splits into barium and krypton atoms, which are highly excited, unstable and artificially radioactive. They throw off gamma and beta radiation, and finally, in an effort to lose mass, they spout neutrons. If these neutrons are slowed by such substances as graphite, paraffin, heavy water or ordinary water, they will touch off other uranium nuclei. In a tiny fraction of a second the reaction will run through a good-sized sample of uranium, containing trillions of atoms, and the result will be a cataclysmic blast...
Shouts & Echoes. The basic secret of radar is that short radio waves behave very much like light. In the spectrum of electromagnetic radiation, which ranges from the extremely short cosmic rays (trillionths of an inch) and gamma rays (which are released in an atomic bomb) to extremely long electric power waves (6,000 miles), radio and light waves are almost next-door neighbors, though light waves are much shorter than radio...
...best drug yet found for African sleeping sickness, according to U.S. Public Health Service doctors, is gamma (paraarsenosophenyl) -butyric acid. In tests conducted for U.S. troops in Africa, the new drug apparently cleared up early cases entirely, helped somewhat in late cases...
