Re: Deadly contamination
Check out my post below.
The effects of small numbers (~100 or less) of nuclear detonations in the atmosphere are not that big a problem on a global scale. Of course, it is still better not to have it happen at all, particularly for those at ground zero.
I do have geiger counters and dosage meters (available as surplus on places like e-bay), but they are for accidents or "dirty bomb" terrorism, not for nuclear explosions on the other side of the planet.
