Single-player, multiplayer. Call of Duty: Modern Warfare 3 is a 2011 first-person shooter video game, jointly developed by Infinity Ward and Sledgehammer Games and published by Activision. The game was released worldwide in November 8 2011 for Microsoft Windows, the Xbox 360, PlayStation 3, Wii, and OS X. [ 1] It is the sequel to Call of Duty ...
Plutonium is a chemical element; it has symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states.
Weapons-grade nuclear material is any fissionable nuclear material that is pure enough to make a nuclear weapon and has properties that make it particularly suitable for nuclear weapons use. Plutonium and uranium in grades normally used in nuclear weapons are the most common examples. (These nuclear materials have other categorizations based on ...
Call of Duty: Modern Warfare III is a 2023 first-person shooter game developed by Sledgehammer Games and published by Activision. It is the twentieth installment of the Call of Duty series and is the third entry in the rebooted Modern Warfare sub-series, following Call of Duty: Modern Warfare II (2022). The game was released on November 10 ...
Isotopes of plutonium (94Pu) Plutonium ( 94 Pu) is an artificial element, except for trace quantities resulting from neutron capture by uranium, and thus a standard atomic weight cannot be given. Like all artificial elements, it has no stable isotopes. It was synthesized long before being found in nature, the first isotope synthesized being ...
Plutonium-239 ( 239Pu or Pu-239) is an isotope of plutonium. Plutonium-239 is the primary fissile isotope used for the production of nuclear weapons, although uranium-235 is also used for that purpose. Plutonium-239 is also one of the three main isotopes demonstrated usable as fuel in thermal spectrum nuclear reactors, along with uranium-235 ...
Criticality accident. A criticality accident is an accidental uncontrolled nuclear fission chain reaction. It is sometimes referred to as a critical excursion, critical power excursion, divergent chain reaction, or simply critical. Any such event involves the unintended accumulation or arrangement of a critical mass of fissile material, for ...
Plutonium-238 (238 Pu or Pu-238) is a radioactive isotope of plutonium that has a half-life of 87.7 years. Plutonium-238 is a very powerful alpha emitter ; as alpha particles are easily blocked, this makes the plutonium-238 isotope suitable for usage in radioisotope thermoelectric generators (RTGs) and radioisotope heater units .
