Discussion Overview

The discussion revolves around the methods and implications of conducting underground nuclear tests, including concerns about environmental damage and the nature of ballistic missile tests. It touches on theoretical aspects of nuclear testing and its geological effects.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions how underground nuclear tests are conducted and whether they cause damage.
  • Another participant suggests that if a nuclear test is deep enough underground, it releases minimal radiation and may create a cavity that collapses, potentially forming a small surface crater.
  • There is a claim that nuclear tests do not generate significant geological effects such as earthquakes.
  • A participant raises a question about the permanence of the cavities created by tests, recalling a show that depicted a crew entering a cavity long after a test.
  • Another participant speculates that a cavity from a low yield device at a shallow depth might remain intact.

Areas of Agreement / Disagreement

Participants express differing views on the permanence of cavities created by nuclear tests and the potential for environmental damage, indicating that the discussion remains unresolved.

Contextual Notes

There are uncertainties regarding the conditions under which cavities may remain intact and the specific geological impacts of different yield devices at varying depths.

Many countries have been found building Nuclear weapons,
I want to know how Nuclear test are done underground, and doesn't it cause any damage?
Many countries do test Missiles(firing them towards sea), are they loaded ones/ unloaded missiles?

WONT NUCLEAR TEST'S CAUSE DAMAGE​
 
Physics news on Phys.org
If a nuclear test is conducted sufficiently deep underground, only a small amount of radiation is released to the environment. An underground test can create a cavity up to several hundred meters in diameter. Soon after the test, the cavity collapses in on itself which may cause a small surface crater as well, depending on the depth. Nuclear bombs are not powerful enough or detonated deep enough to cause earthquakes or any other significant geological effect.

Ballistic missile tests performed by North Korea and Iran are not loaded with warheads, they are testing the functionality of the launch and guidance system.
 
Do they always collapse? I think I saw a show on TV once where they sent a crew down into one of these cavities, decades after the test, of course.

Maybe I'm thinking of something else.
 
I don't know. A cavity from a low yield device at a relatively shallow depth might remain intact.
