BACKGROUND
In 1954, the Soviet Union established its largest nuclear testing grounds at Novaya Zemlya.[1,2]. During the testing program, the Soviet Union conducted tests at different sites in several zones, the numbers and designations of which frequently changed.[3] Most of the testing was consolidated in three zones at Novaya Zemlya (please see the map of Novaya Zemlya). At Zone A in the Chernaya Gulf region, low- and medium-yield atmospheric explosions, and underwater and surface nuclear tests were staged from 1955-1962. After 1963, six underground tests were staged.[3] From 1964 through 1990, nuclear tests were conducted in deep underground shafts in Zone B on the Gulf of Matochkin Shar's southern bank.[2,3] Zone B also houses the test site's administrative and scientific center.[3] Zone C, where atmospheric tests were conducted from 1957 through 1962, is located on Sukhoy Nos peninsula, north of Matochkin Shar strait. In February 1992, President Boris Yeltsin signed the decree On the Test Site at Novaya Zemlya, designating the official name of the site as the Central Test Site of the Russian Federation.
