Sept. 12, 1961 - The Soviet Union conducted the seventh atomic test in its current series by detonating a multi-megaton device in the atmosphere early today at its Arctic proving ground. The Atomic Energy Commission said the detonation, presumably of a hydrogen bomb, took place in the vicinity of the island of Novaya Zemlya (pictured). The island, which lies between the Barents and Kara Seas, has been used by the Soviets in recent years to test large thermonuclear weapons. On Sunday, the Soviet Union tested two devices in the same area.
