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 ...
Since the E1 component of nuclear EMP depends on the prompt gamma-ray output, which was only 0.1% of yield in Starfish Prime but can be 0.5% of yield in low-yield pure nuclear fission weapons, a 10 kt (42 TJ) bomb can easily be 5 * 8%= 40% as powerful as the 1.44 Mt (6.0 PJ) Starfish Prime at producing EMP.
Sub-MeV radiation from a nuclear explosion may be more important in (empty) space. Given this realization, during the 1960s [3] the U.S. military began to investigate whether military systems could be tested for their response to nuclear-weapon generated pulsed x-rays with flash x-ray machines. At the time these were fairly small, primarily ...
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.
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 the nuclear energy sector continues to grow, the international rhetoric surrounding nuclear warfare intensifies, and the ever-present threat of radioactive materials falling into the hands of dangerous people persists, many scientists are working hard to find the best way to protect human organs from the harmful effects of high energy radiation.
All nuclear weapons up to about 10 kilotons in yield have prompt neutron radiation [2] as their furthest-reaching lethal component. For standard weapons above about 10 kilotons of yield, the lethal blast and thermal effects radius begins to exceed the lethal ionizing radiation radius.
It has a half-life of 30 years, and decays by beta decay without gamma ray emission to a metastable state of barium-137 (137m Ba). Barium-137m has a half-life of a 2.6 minutes and is responsible for all of the gamma ray emission in this decay sequence. The ground state of barium-137 is stable. The photon energy (energy of a single gamma ray) of ...
