The United States opened the nuclear era in July 1945 with the test of a 20-kiloton atomic bomb at Alamogordo, New Mexico, in July 1945, and then dropped atomic bombs on the Japanese c ...
Nuclear weapons testing did not produce scenarios like nuclear winter as a result of a scenario of a concentrated number of nuclear explosions in a nuclear holocaust, but the thousands of tests, hundreds being atmospheric, did nevertheless produce a global fallout that peaked in 1963 (the bomb pulse), reaching levels of about 0.15 mSv per year ...
The test weapons produced a combined yield of about 77–78.6 Mt of TNT in explosive power. After the inhabitants agreed to a temporary evacuation, to allow nuclear testing on Bikini, which they were told was of great importance to humankind, [3] two nuclear weapons were detonated in 1946. About ten years later, additional tests with ...
The USA also conducted one live weapons test involving a missile launched nuclear depth charge: Test of the RUR-5 ASROC during the Dominic-Swordfish test on May 11, 1962. The Soviet Union tested nuclear explosives on rockets as part of their development of a localized anti-ballistic missile system in the 1960s. Some of the Soviet nuclear tests ...
MOSCOW (Reuters) -President Vladimir Putin said on Thursday that Russia had successfully tested a potent new strategic missile and declined to rule out the possibility it could carry out weapons ...
In addition to the two superpowers, France and China are known to have tested neutron or enhanced radiation bombs. France conducted an early test of the technology in 1967 [25] and tested an actual neutron bomb in 1980. [26] China conducted a successful test of neutron bomb principles in 1984 and a successful test of a neutron bomb in 1988.
Since conducting its first nuclear test more than a decade ago, North Korea has advanced its weapons capabilities, with the ambition of miniaturizing a warhead so that it can fit on a long-range ...
Underground nuclear testing is the test detonation of nuclear weapons that is performed underground. When the device being tested is buried at sufficient depth, the nuclear explosion may be contained, with no release of radioactive materials to the atmosphere.
