Long-term biological consequences of nuclear war
Science (New York, N.Y.)
|December 23, 1983
Summary
A large-scale nuclear war could trigger a nuclear winter, causing global starvation and mass extinctions. Human survival is uncertain, with potential for extinction or reduction to prehistoric population levels.
Area of Science:
- Environmental Science
- Ecology
- Climate Science
Background:
- Large-scale nuclear war poses catastrophic threats beyond immediate destruction.
- Post-war environmental conditions could be extreme and long-lasting.
Purpose of the Study:
- To assess the potential long-term environmental and biological consequences of a large-scale nuclear war.
- To evaluate the impact on global ecosystems and human civilization.
Main Methods:
- The study likely involves climate modeling and ecological impact assessments.
- Analysis of potential effects of reduced sunlight, extreme cold, and radiation.
Main Results:
- Severe disruption of natural and agricultural ecosystems is predicted.
- Prolonged periods of subfreezing temperatures, darkness, and radiation exposure.
- Global biosphere disruption, potentially affecting both hemispheres.
Conclusions:
- Civilization's biological support systems could be destroyed.
- Mass extinctions of plants, animals, and microorganisms are possible.
- Human extinction or drastic population reduction is a plausible outcome.

03:18Nuclear 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.

02:50Nuclear 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...
02:36Nuclear 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.

03:20Nuclear 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...
02:59Biological Effects of Radiation
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they produce ions...
01:23Toxicity Testing in Animals
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
