...theory of neutrinos predicts that when one hits a 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...
...allowed to the average individual up to 30 years, about 3 to 4 r, the committee was shocked to discover, is being currently expended on medical ", and dental X rays, which have the same effect as gamma rays from radioactive sources. A dental X ray may give .005 r to the gonads, and general fluoroscopic examinations may give 2 r or more. The committee suggests that doctors and dentists should go easy with X rays. Patients who read the committee's report (especially those who intend to have more children) will surely think twice before they permit prolonged...
...meet the plane at Pittsburgh, and he had already conferred by phone with Virus Expert Jonas Salk, who was at a meeting in New York City. Salk's advice: give each member of the crew, and the baggage smashers in Baltimore and Washington, a double dose of gamma globulin and a dose of polio vaccine, and disinfect the plane. The passengers were allowed to take their luggage after it had been sluiced down with alcohol. The plane's interior got a dousing with hydrogen peroxide (the entire stock of three drugstores), Lysol and isopropyl alcohol. After consulting...
