...Soviets announced in July that they would open a new round of nuclear tests on Aug. 5 in the Arctic testing ground of Novaya Zemlya. Before that, the last reported Russian blast took place in November 1961. It was with more than passing curiosity, therefore, that Western correspondents in Moscow last week came upon a photograph that appeared in the military newspaper Red Star on Aug. 3-two days before the new series began. It showed Russian tanks lumbering across a rolling landscape; there in the background was the mushroom cloud of a nuclear explosion. The caption said the picture...
First measurements came from radio sensitive Japan, where radioactivity had sunk to a comfortably low winter level after last fall's Russian tests in Novaya Zemlya. In December the index figure was an insignificant 6.77 millimicrocuries.* Radioactivity stayed low during January and February, but since then it has climbed steeply. By March it had reached 29-48 millimicrocuries, and scientists of Japan's Meteorological Institute estimate that it will reach about 50 millimicrocuries for the month of April. After the notably "dirty" Soviet tests of 1958, the figure peaked at 94.45 in May of 1959. Japanese meteorologists point...
When the Soviet 50-megaton test-bomb exploded on Novaya Zemlya last October, it set the earth's whole atmosphere vibrating. Last week in London, Seismologists Eric Carpenter, George Harwood and Thomas Whiteside reported how the bomb waves looked when they were recorded on the microbarograph at Britain's Atomic Weapons Research Establishment...
...bomb exploded at 8:33 a.m. British time. By 11:44 a.m., the first air wave reached England, having taken 3 hr. 11 min. to travel from Novaya Zemlya at the speed of sound-about 700 m.p.h. At 4:40 p.m. on the next day, the barograph pen jiggled again, recording the air waves that had taken the long path and circled the earth in the opposite direction and approached England from the southwest. At ten minutes past midnight on Nov. 1, the first wave swept over England again, making almost as strong a record as on its first trip...
...filtering into the AEC, but Seaborg and his colleagues will be picking up clues for weeks to come before they get the detailed answers as to what the Soviet Union actually tested and accomplished. Known is the fact that Russian tests at three different sites-northern and southern Novaya Zemlya and Semipalatinsk in the Soviet Arctic-have totaled more than 110 megatons of yield, bringing the total Russian test yield to date to about 160 megatons v. 125 megatons from known U.S. and British tests since 1946. The Soviet tests ranged from about 10 kilotons (10,000 tons...
