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?
Does being under water provide any protection from a asteroid?
