...Since the RS-70 could not be adapted for airborne alert-patrolling the skies with a full load of arms-it would be a sitting duck on the ground for any surprise attack. Nor could the high-altitude RS-70 dodge enemy radar by streaking in for low-level attacks...
...have been climbing too steeply to make a safe turn. Said Halaby: "It appears to have been some kind of mechanical failure in some part of the control system." Pilots theorized that the strict antinoise laws that force them to ascend rapidly after take-off and make perilous low-level maneuvers over heavily populated areas might have caused the crash of the huge jet. The Air Line Pilots Association has long argued that noise-abatement regulations were endangering flight safety...
...product of their activity is radioactive waste that cannot be flushed or tossed away. There is low-level radioactivity, for instance, in the carcasses of laboratory mice injected with isotopes-and in the hypodermic needle that injected them, and in the laundry water that washed the laboratory coat of the technician. In 1955 the total amount of land-buried waste in the AEC's main burial grounds came to 316,000 cu. ft.; by last year that figure...
...packing necessary for safe sea disposal makes it expensive: to dispose of radioactive waste at sea costs $10 to $20 per cu. ft. In comparison, disposal firms can bury low-level waste on land for 70? a cu. ft. in atomic graveyards maintained by AEC at Oak Ridge, Tenn., and Idaho Falls. Here drums are deposited in 15-ft. holes and covered with concrete and earth. The disposal fields cost the U.S. $6,000,000 a year to maintain, and AEC expects to establish from five to ten more...
Clean Record. Inevitably, a few accidents have occurred. Last year in Long Beach, Calif., a barrel of low-level waste blew up and scattered its contents over almost a mile because of improper handling by the disposal company, which lost its AEC license. In Antioch. Calif., two years ago, another low-level barrel leaked slightly into the San Joaquin River, from which Antioch draws its drinking water; after much testing and explaining by AEC, townspeople were persuaded that the water was still safe...
