Show H-Bomb Could Kill Everyone in Nation Dr. Harrison Brown, associate professor in the Institute for Nuclear Studies at the University of Chicago and an atom scientist during the war, has come up with some shattering warnings about the hydrogen bomb. . , Dr. Brown said: A string of hvdro?en bomb ex- ' plosions off the Pacific coast could kill every living thing in the United States with radioactivity. Similarly, Similar-ly, a string of, H-bombs exploded along the line "of the iron curtain could kill every living thing 3,000 miles into Russia. "If the bomb works at all," he declared, "there may well be no upper limit (or at least a very high limit) to the size of the nuclear explosion ex-plosion that may be created. One might well ask, of what use is a bomb that will destroy an area greater than, say, 500 square miles, by its blast effect? "The answer is that one would not use such a weapon to destroy by blast effect. Instead, one would utilize the radioactivity that could be produced by such an exDlosion and permit the westerly winds to carry it over the enemy territory." The radioactivity of a hydrogen bomb could be increased greatly by adding material that would become be-come radioactive to the other ingredients in-gredients of the weapon. Dr. Brown visualized a series of hydrogen bomb explosions carried out along a north - south line through Prague. The radioactivity produced by the explosions would be carried eastward .by the pre- vailing westerly winds. "All life would be destroyed," he said, "within a stvip 1,500 miles wide, extending from Leningrad to Odessa, and 3,000 miles deep, extending ex-tending from Prague to the Ural Mountains. "By the time the radioactivity passed the Urals (approximately three days) the intensity would be lower and the destruction would be less. By the time the Pacific had been crossed and the West Coast of America reached the radioactivity radioactiv-ity would not be dangerous." Admitting that many human beings be-ings might survive such an attack by protecting themselves, Dr. Brown declared that unprotected animals and vegetation within the area would be destroyed. "Such an attack," he said, "would produce a scorched earth of an extent unprecedented in history." his-tory." Russia could use the same tactics tac-tics on the United States, he ' added. Hydrogen bomb explosions could be set off on a north-south line in the Pacific approximately 11,000 miles west of California. |
