...reach the solar system's largest planet, a flight that could take two years or more. Pioneer F will have to survive a hazard never before encountered by a spacecraft: it will have to pass through the asteroid belt, which consists of some 50,000 asteroids that circle the sun between the orbits of Mars and Jupiter. If Pioneer runs the rocky gauntlet successfully, the way will be cleared for further explorations of the outer planets by unmanned spacecraft making Grand Tours* later in the decade, as well as future flights by man himself. A serious accident...
...time. Such materials may accumulate to 1000 times the radioactivity of one Hiroshima-sized bomb. Although a reactor cannot sustain a nuclear explosion, the presence of many hundreds of tons of material which is one billion times more toxic than any known industrial substance is an unparalleled hazard, especially during fuel replacement. Such replacement is an extraordinarily delicate operation and, in the case of Con Edison's Indian Point ?I plant at Buchanan, N. Y., took six weeks during which 40 of the 120 fuel elements were removed, each weighing nearly four tons...
Even worse, though, the plant is not equipped to trap any gas released during reprocessing and over 30,000 curies of gaseous radioactive krypton (K85) are released every month. One curie, fully absorbed, is fatal. With prevailing winds from the west a serious hazard is posed for Buffalo 30 miles to the northeast and for Vermont, which thought its problems had ended when the wastes first left the state...
...eliminate the dust, the soap companies began making their products in the form of tiny, coated beads. As for skin irritations, the detergent makers tested their products on many volunteers and pronounced enzymes safe. Disagreeing, the American Academy of Allergy declared in January that enzymes are indeed a potential hazard. The Federal Trade Commission has just completed a study of enzymes but has not yet released its findings...
Though the detergent industry continues to defend the use of phosphates, manufacturers are casting about for a substitute cleaning agent. NTA, a nitrogen-based ingredient, seemed briefly promising until it was found to be a potential health hazard. A return to soap chips is not feasible because they would literally gum up the works of most automatic washing machines...
