Follow-up of Could the entire world have been destroyed by the existing nuclear arsenal in 1962?
- Is it safe to grow food on land that was hit by nuclear bombs? Or will such food kill/fatally sicken anyone that eats it?
- If the food is lethal, how long would it take for land to become arable again?
Expect that bombs are not only detonated in the air, but also on the ground to hit bunkers.
I know that Pripyat and Chernobyl is now flourishing with all sorts of plants, but I wonder if that is safe for eating and whether it would be different if the cause was a nuclear explosion that would have wiped out most plants in its blast, so that it would first have to regrow?
Most radiation from a nuclear explosion is gone in a matter of days, but the protagonist stays in their bunker for about 6 months after which they emerge to scavenge the world because the bunker is running out of supplies. Would it be possible for the player to discover farms growing crops that are perfectly edible?
Edit
I consider it "safe" when people don't die within a year as a direct result from eating it. Only an increased risk of cancer I will consider "safe".
