Radiological warfare is any form of warfare involving deliberate radiation poisoning or contamination of an area with radiological sources.. Radiological weapons are normally classified as weapons of mass destruction (WMDs), [1] although radiological weapons can also be specific in whom they target, such as the radiation poisoning of Alexander Litvinenko by the Russian FSB, using radioactive ...
Canada is a member of every international disarmament organization and is committed to pushing for an end to nuclear weapons testing, reduction in nuclear arsenals, a ban on all chemical and biological weapons, bans on weapons in outer space, and blocks on nuclear proliferation. However, in recent years it has become less vocal on the issue of ...
As Canada did not own any nuclear weapons outright, much of Canadian anti-nuclear activism focused on eliminating their presence in Canada. Advocacy for nuclear-weapon-free zones during the cold found the most success on the municipal level, [32] while the federal level met similar proposals with little interest.
This form of radioactive contamination is known as nuclear fallout and poses the primary risk of exposure to ionizing radiation for a large nuclear weapon. Details of nuclear weapon design also affect neutron emission: the gun-type assembly Little Boy leaked far more neutrons than the implosion-type 21 kt Fat Man because the light hydrogen ...
Map of nuclear-armed states of the world NPT -designated nuclear weapon states (China, France, Russia, United Kingdom, United States) Other states with nuclear weapons (India, North Korea, Pakistan) Other states presumed to have nuclear weapons (Israel) NATO or CSTO member nuclear weapons sharing states (Belgium, Germany, Italy, Netherlands, Turkey, Belarus) States formerly possessing nuclear ...
On 2 July 1967, at 14:19 UTC, the Vela 4 and Vela 3 satellites detected a flash of gamma radiation unlike any known nuclear weapons signature. [8] Uncertain what had happened but not considering the matter particularly urgent, the team at the Los Alamos Scientific Laboratory, led by Ray Klebesadel, filed the data away for investigation. As ...
There are two main considerations for the location of an explosion: height and surface composition. A nuclear weapon detonated in the air, called an air burst, produces less fallout than a comparable explosion near the ground. A nuclear explosion in which the fireball touches the ground pulls soil and other materials into the cloud and neutron ...
Gamma-ray bursts were discovered in the late 1960s by the U.S. Vela nuclear test detection satellites. The Velas were built to detect gamma radiation pulses emitted by nuclear weapon tests in space. The United States suspected that the USSR might attempt to conduct secret nuclear tests after signing the Nuclear Test Ban Treaty in 1963. While ...
