...prize went to Rudolf L. Mössbauer, 32, of West Germany, who is now working at Caltech. In 1958, while he was still a graduate student at Munich's Institute of Technology, Mössbauer published in Zeitschrift für Physik a sensational paper reporting that gamma rays given off by certain radioactive isotopes can be used for infinitely delicate measurements. When projected toward suitable absorbers, those gamma rays can gauge extremely small motions and distances. They have even been used to register the slight change of frequency that results when they travel a few feet vertically...
Roentgen is a unit used in measuring gamma and X rays. It is named after Wilhelm Konrad Röntgen, a German physicist who discovered X rays...
...Gamma Rays, generated by a nuclear explosion, are similar to X rays and form the radiation that is most dangerous to life. They are the main reason for fallout shelters...
...unshielded nuclear reactor for Air Force research on atom-powered airplanes. The reactor was set among wooded hills and abandoned fields that were reverting to forest, and in June 1959 it was allowed to operate for a short period at high level, spraying its surroundings with gamma rays and neutrons, the total dose simulating the effect of fallout after a nuclear...
...Last week, after much toil by Enders and others, a group of Pennsylvania physicians and virologists announced that they had successfully tested a measles vaccination technique. Children are first inoculated with Enders vaccine, which gives nearly 100% protection. Then, almost immediately, they are injected in the same arm with gamma globulin, which holds undesirable side effects, such as fever and rash, to a minimum. The Public Health Service still must approve the new measles technique, establish manufacturing standards. If all goes well, a vaccine will be on the market next year, just as measles heads toward its next cyclical peak...
