Fear of atomic radiation-especially from the fallout from nuclear weapons tests-has touched nearly all "mankind. Neither scientists, statesmen nor churchmen agree about...

On March 1, 1954 came Test Bravo, the gigantic U.S. thermonuclear explosion in the Pacific that sifted "death ash" on Japanese fishermen 71 miles away. Public anxiety increased when it became known that Bravo had made the whole of the earth's atmosphere detectably more radioactive...
Danger of genetic damage from fallout radiation that affects the reproductive organs does not alarm Libby either. The amount is too small, he says, "from 0.7% to about 3% of the natural radiation exposure." Another Libby example: a person moving into a concrete-block house in certain countries may get up to 100 times as much additional radiation from naturally radioactive elements in the concrete as he is getting from present fallout. He recognizes that fission products from past tests are still stored in the stratosphere and that they will soon be joined by the products of new tests. This...
...scientists agree with Dr. Libby. Most vocal is Physicist Ernest O. Lawrence of the University of California, Nobel Prizewinner (1939) and inventor of the cyclotron, who finds it "beyond my comprehension" that any reputable scientist should worry about fallout from weapons tests. He thinks the tests could continue forever without damage...
