...Sprint caused an incoming ICBM to explode at an altitude of 50 miles or less, the results would be more devastating. Quoting from an AEC publication, Lapp reported that in a test of a megaton-range weapon exploded 50 miles over the Pacific in 1958, exposed rabbits had suffered retinal burns at slant distances up to 345 miles from the blast. Furthermore, the AEC document read, "it is felt that there would be some danger to human beings at distances greater than 200 miles under similar circumstances...
...Atomic Energy Commission. While not disputing that items in the public-works section of the bill could be cut, I feel journalistic accuracy should reflect the dual nature of the Public Works and Atomic Energy Commission Appropriation Bill. You might wish to express your opinion on whether the AEC portion should be cut. HOWARD W. ROBISON Congressman 33rd District, New York Washington...
Last week's nuclear explosion, on the other hand, should have produced such extensive shattering and cracking, according to AEC experts, that as much as 70% of the gas i in the surrounding rock should flow into the well over a 20-year period, cotnpared with only 10% that would be recovered by hydraulic fracturing or nitroglycerin blasting. Within a minute after the searing blast formed a 160-ft.-diameter cavity in the earth, they calculate, the roof of the cavity should Save begun to collapse (TIME, Nov. 3), eventually forming a chimney of fractured rock as tall...
...Congress and the AEC approve, scientists will drill a 20-in. shaft 1,200 ft. down into the ore deposit. They will then lower a 20-kiloton device to the bottom, plug the shaft, and set off a nuclear blast. From experience with previous tests, the AEC knows that the explosion will create tremendous pressures that will literally push the rock away from the blast center, fracturing it in all directions. The result will be a cavity about 200 ft. in diameter; the surface of the earth will quake, but the AEC does not expect any radioactive debris...
Scientists from the AEC, the U.S. Bureau of Mines, the University of California's Lawrence Radiation Laboratory and the Kennecott Copper Corp. have proposed a test (named Project Sloop* by the AEC) near Safford, Ariz. There, under a layer of volcanic rock more than 500 ft. thick, Kennecott test drillings have revealed a 2-billion-ton reserve of ore containing about 4/10 of 1% of copper...
