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 ...
The deposited cobalt-60 would have a half-life of 5.27 years, decaying into 60 Ni and emitting two gamma rays with energies of 1.17 and 1.33 MeV, hence the overall nuclear equation of the reaction is: 59 27 Co + n → 60 27 Co → 60 28 Ni + e − + gamma rays. Nickel-60 is a stable isotope and undergoes no further decays after the ...
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 ...
Intense thermal radiation at the hypocenter forms a nuclear fireball which, if the explosion is low enough in altitude, is often associated with a mushroom cloud. In a high-altitude burst where the density of the atmosphere is low, more energy is released as ionizing gamma radiation and X-rays than as an atmosphere-displacing shockwave.
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 incident prompted the U.S. Nuclear Regulatory Commission and Customs Service to install radiation detection equipment at all major border crossings. [ 14 ] [ 15 ] March 19, 1984 – Casablanca, Morocco – A 16.3 Ci (600 GBq) iridium-192 source was lost and taken home by a laborer, who placed the source on a table in the family bedroom.

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 ...
