# Does being in the air provide any protection from an asteroid?

How does radiation and shock waves from a radioactive asteroid or atomic explosion disperse throughout Earth's atmosphere?

Are there specific areas on Earth that are less likely to receive the shock wave or radiation by being on the other side of the Earth and/or land or wind characteristics like being in a deep valley?

I'm trying to go with the worst case survivable scenario if the asteroid hit with the possibility of hitting a nuclear reactor, arsenal or deposit of uranium.

This is from a broad question that I am breaking up in 3 questions. Feel free to edit.

Which of these scenarios would have a smaller chance of being struck?

• In the air of some type blimp or aircraft on the opposite side of the Earth?

• The link to the asteroid question has an answer posted, so there's a solution to that one. – Eevee Mar 3 '18 at 17:18

• So you're asking it again (heads up: it might be marked [duplicate])? – Eevee Mar 3 '18 at 17:30
• I think it's clearer now. But why do you think there would be a 'natural atomic explosion from an asteroid impact'? Asteroid or meteor impacts release simply gravitational energy, not nuclear ones. – AtmosphericPrisonEscape Mar 4 '18 at 15:40
• I think you have a fundamental flaw in your thinking. "Radiation" isn't really a separate thing, it's just dust which happens to have radioactive atoms in it. So the dispersal of radioactive fallout isn't really different from say ash (which really isn't ash :-)) from a volcano or smoke from a forest fire. – jamesqf Mar 5 '18 at 20:20
