The Treaty banning Nuclear Weapon Tests In The Atmosphere, In Outer Space And Under Water, often abbreviated as the Partial Test Ban Treaty (PTBT), Limited Test Ban Treaty (LTBT), or Nuclear Test Ban Treaty (NTBT) (although the latter also refers to the Comprehensive Test Ban Treaty) is a treaty prohibiting all test detonations of nuclear weapons except underground. It was developed both to slow the arms race (nuclear testing was, back then, necessary for continued nuclear weapon advancements), and to stop the excessive release of nuclear fallout into the planet’s atmosphere. It was signed by the Governments of the USSR (represented by Andrei Gromyko), the UK (represented by Sir Alec Douglas-Home)
Atmospheric 14C, New Zealand[1] and Austria[2]. The New Zealand curve is representative for the Southern Hemisphere, the Austrian curve is representative for the Northern Hemisphere. Atmospheric nuclear weapon tests almost doubled the concentration of 14C in the Northern Hemisphere [3]. The Delay of some years after the test ban of the peak on the Southern Hemisphere can be explained by the time for the propagation of C-14 from the Northern Hemisphere to the Southern Hemisphere. and the USA (represented by Dean Rusk), named the "Original Parties", at Moscow on August 5, 1963 and opened for signature by other countries. It was ratified by the U.S. Senate on September 24, 1963 by a vote of 80 to 19. The treaty went into effect on October 10, 1963.[1] [2] Much of the initiative for the treaty had its focus in what was the rising concern about radioactive fallout as a result of nuclear weapons testing underwater, in the atmosphere, and on the ground’s surface, on the part of the nuclear powers. These concerns became more pronounced after the United States successfully tested a hydrogen bomb and a thermonuclear device with the power of eight megatons of TNT in the early 1950s and when the USSR detonated a 50-megaton nuclear warhead in 1961. Initially, the Soviet Union proposed a testing ban along with a disarmament agreement dealing with both conventional and nuclear weapon systems. The Western nuclear

powers and the Soviet Union traded positions on this issue over the course of negotiations in the 1950s through offers and counteroffers proposed under the aegis of the U.N. Disarmament Commission. It was only later during 1959 and into the early 1960s that the United States, the United Kingdom, and the Soviet Union agreed to detach a general agreement on nuclear disarmament from a ban on nuclear weapons testing. The Soviet Union, however, only agreed in principle to a testing ban with no verification regime or protocols. It was over what measures and the method by which they could be effectively be carried out that caused much of the deadlock in the latter half of 1961 over a test ban agreement. The problem of detecting underground tests — that is, distinguishing it from an earthquake — proved to be particularly troublesome. Therefore the United States and United Kingdom insisted on intrusive, inspection-based control systems as a means to verify compliance. The Soviet Union, on the other hand, maintained the position that surveillance and seismic detection equipment operated from outside the boundaries of any signatory was adequate to verify compliance. The Western powers felt that any agreement not subject to a control system rigorous enough to verify compliance would set a bad precedent in nuclear arms control for future agreements. Deadlock ensued until July 1963 when Premier Khrushchev signaled his willingness to forgo a ban that would include underground testing. In effect, this meant the Soviet Union would agree to a test ban in the atmosphere, outer space, and under water environments; a position the Western powers had long favored as an alternative to a more comprehensive (underground environment) ban. This opened an opportunity for a threepower meeting among the United States, the United Kingdom, and the Soviet Union on July 15, 1963 in Moscow. The Moscow negotiations, in reflecting the long deliberations that had gone on for nearly a decade, took relatively little time as the treaty was signed by representatives of the three governments only 21 days later.
