...protein contains 2.2 percent cadmium...
...battle begins. It rages within the four relentless walls like a chain reaction in a uranium furnace. Time and again a scene starts to run wild; but just at the last instant, Scriptwriter Rose inserts the dramatic equivalent of a cadmium rod-a space of near inactivity. And the excitement simmers down to the point where he can safely start it up again...
...proton (an infrequent event), a positron (positive electron) is emitted, and the proton turns into a neutron. Both new particles are unstable. The positron hits an electron, and both are "annihilated," turning into gamma rays. The neutron is absorbed by almost any kind of matter, and if a little cadmium is around, the neutrons captured by it give another burst of energy...
...Eyes. The Reines and Cowan apparatus for detecting neutrinos contains more than 1,000 gallons of liquids (water and hydrocarbons) that are rich in protons. The water contains dissolved cadmium to capture neutrons, and the hydrocarbons give scintillations of light when gamma rays pass through them. The scintillations are recorded by 330 photomultiplier tubes that watch the scintillating liquid like large, unblinking eyes...
...Reines and Cowan built the world's biggest and most complex scintillation counter. They filled a 28-in. cylinder with toluene, a scintillating liquid that contains lots of protons. In the toluene, they dissolved a small amount of a cadmium compound. Then they surrounded the cylinder with 90 photomultiplier tubes hooked up to respond to pairs of flashes caused by positrons and neutrons...
