Invierno nuclear: consecuencias globales de múltiples explosiones nucleares
Resumen
Una guerra nuclear podría causar un cambio climático global severo, incluyendo frío extremo y oscuridad, amenazando a los sobrevivientes. Incluso un conflicto de 100 megatones puede desencadenar consecuencias atmosféricas y climáticas significativas en todo el mundo.
Área de la Ciencia:
- Ciencias de la atmósfera Ciencias atmosféricas.
- Climatología y climatología.
- Estudios de invierno nuclear Estudios de invierno nuclear.
Sus antecedentes:
- Los modelos de erupción volcánica proporcionan una base para evaluar los impactos de la guerra nuclear.
- Estudios anteriores ponen de relieve las posibles perturbaciones atmosféricas de los eventos a gran escala.
Objetivo del estudio:
- Investigar las consecuencias atmosféricas y climáticas globales de una guerra nuclear.
- Para determinar el impacto potencial de las detonaciones nucleares en la radiación solar, la temperatura y la distribución de la radiactividad.
Principales métodos:
- Utilizó modelos desarrollados para estudios de erupciones volcánicas.
- Intercambios nucleares simulados de rendimientos variables (por ejemplo, de 100 megatones a 5000 megatones).
- Se analizó la inyección de polvo y humo, la atenuación de la radiación solar, los cambios de temperatura y la lluvia radiactiva.
Principales resultados:
- Es probable que haya una reducción significativa de la radiación solar y temperaturas bajo cero debido al polvo y el humo.
- Incluso conflictos relativamente pequeños (100 megatones) pueden causar importantes efectos ópticos y climáticos.
- Las lluvias radiactivas y la radiación UV aumentada representan amenazas a largo plazo para los sobrevivientes.
Conclusiones:
- La guerra nuclear representa una seria amenaza para el clima global y la supervivencia humana.
- El umbral de consecuencias climáticas severas puede ser más bajo de lo que se pensaba anteriormente.
- El transporte atmosférico de partículas y radioactividad puede afectar a ambos hemisferios.

Nuclear Fission
Many heavier elements with smaller binding energies per nucleon can decompose into more stable elements that have intermediate mass numbers and larger binding energies per nucleon—that is, mass numbers and binding energies per nucleon that are closer to the “peak” of the binding energy graph near 56. Sometimes neutrons are also produced. This decomposition of a large nucleus into smaller pieces is called fission. The breaking is rather random with the formation of a large number of different...
Nuclear Power
Controlled nuclear fission reactions are used to generate electricity. Any nuclear reactor that produces power via the fission of uranium or plutonium by bombardment with neutrons has six components: nuclear fuel consisting of fissionable material, a nuclear moderator, a neutron source, control rods, reactor coolant, and a shield and containment system.
Nuclear Fuels
Nuclear fuel consists of a fissile isotope, such as uranium-235, which must be present in sufficient quantity to provide a...

Nuclear Transmutation
Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed protons being...
Nuclear Stability
Protons and neutrons, collectively called nucleons, are packed together tightly in a nucleus. With a radius of about 10−15 meters, a nucleus is quite small compared to the radius of the entire atom, which is about 10−10 meters. Nuclei are extremely dense compared to bulk matter, averaging 1.8 × 1014 grams per cubic centimeter. If the earth’s density were equal to the average nuclear density, the earth’s radius would be only about 200 meters.

Nuclear Fusion
The process of converting very light nuclei into heavier nuclei is also accompanied by the conversion of mass into large amounts of energy, a process called fusion. The principal source of energy in the sun is a net fusion reaction in which four hydrogen nuclei fuse and ultimately produce one helium nucleus and two positrons.
A helium nucleus has a mass that is 0.7% less than that of four hydrogen nuclei; this lost mass is converted into energy during the fusion. This reaction produces about...

Global Climate Change
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
