...anniversary of the world's first test, in Grand Rapids, of an attempt to fluoridate water supplies so that children would need fewer fillings-and fewer extractions. The Grand Rapids program was soon followed by a similar test in Newburgh, N.Y. The results were checked against the dental decay rate of children in comparable cities without fluoridation: Muskegon, Mich., and Kingston...
...ideal amount of fluorine salts in public water has been established as one part per million. Less than that gives inadequate protection against decay; double that, or more, causes mottling. The question that has agitated hundreds of U.S. communities is whether fluorides,-even in a dilution of one part per million, are safe. The answer, from scientifically controlled studies in many countries, is an unequivocal yes on the basis of the evidence. But strident opposition has come from Christian Scientists, the Ku Klux Klan, the John Birch Society and a handful of physiologists and dentists. They assert that fluorides (among...
Admittedly, fluoridation of water is not the whole answer to dental health. The fluorides protect the sides of the teeth more than the grinding surfaces of molars, which have tiny fissures in them where decay often begins, especially in adolescents. For these surfaces, Dr. Michael Buonocore of the Eastman Dental Center in Rochester has devised a technique of coating with plastic film. Fluoridated toothpastes have won the approval of the American Dental Association (though not of all individual dentists) as a useful adjunct to water fluoridation. Another possibility, on which the National Institute of Dental Research is working...
They are probably right. Americium emits almost exclusively alpha particles, the nuclei of helium atoms produced by the isotope's slow decay into lighter elements. The alpha particles are so weak that they remain confined inside the victim's body. While contagion is virtually impossible, this is only slight comfort to the victims. As americium spreads through the body, it may linger in such areas as the liver, spleen and lymph system and eventually settle into the marrow of the bones. According to Pittsburgh Radiologist Niel Wald, a leading radiation specialist, the effect over a year-long period...
...their views on the people who are directly affected by the laws. Their view of morality seems to be limited to disapproval of premarital sex. "Sex, sex, sex-that's all I've heard this morning," ranted William Carey (R-Suffolk). In fact, his fifteen-minute diatribe on the decay of morality in young people was the only prolonged discussion of sexual intercourse the committee heard. They listened sympathetically. The chairman at one point asked the spectators, most of whom supported the bill, to quiet down and listen to Carey. "You don't have a monopoly on the right point...
