...continued testing, at Nevada and in the Pacific, from Operation Teapot through Operation Hardtack in October of 1958. During that period, the scientists tested tactical atomic weapons, dropped an H-bomb from a B-52, fired a depth charge, triggered a missile warhead 100 miles high, tried fallout-free underground testing...
...Soviet tests of 1958, the figure peaked at 94.45 in May of 1959. Japanese meteorologists point out that their last winter was very dry with rainfall registering only about half that of three years ago. They predict that when the heavy spring rains arrive, they will pull down enough fallout to equal or exceed the 1959 peak...
...where fallout watchers are neither as prompt with their reports as the Japanese nor as frank, few figures have been released. But radioactivity is known to be showing its expected spring rise. In the Northern states cows are still feeding mostly on fodder gathered last fall before the Soviet tests, and their milk is still low in radioactivity. But Southern cows are already grazing on green grass, and the spring fallout that has collected on it is passing into their milk. As spring moves north and the grass greens up in Vermont and Wisconsin, the radioactivity of Northern milk will...
...authorities, including the Atomic Energy Commission, the Public Health Service and the Weather Bureau, feel sure that the 1962 fallout will probably equal or exceed the 1959 peak, but they are not alarmed. The fission energy yield of the Soviet 1958 tests was 10 to 15 megatons. The total energy of last fall's Soviet tests was much greater (170 mega tons), but most of it came from nuclear fusion, which creates little fallout. Only about 25 megatons came from nuclear fission of uranium or plutonium, and since many of the Russian tests were exploded at high altitudes, their...
Even if the 1962 spring fallout sets a new record, says the Public Health Service, it is not likely to endanger health...
