Its also interesting that the topic is about Honest Hearts because in Honest Hearts it tells us how long the radiation lasted:
Randall Clark Notes:
Oct 31, 2077: "Black rain falling outside. http://fallout.wikia.com/wiki/Geiger_counter jumping. Should let it kill me but bottling water from back of cave all the same."
Nov 2, 2077: "Sounds dead outside, but can't look. Geiger goes crazy 15 feet from cave mouth. Do the math. Radiation goes down before water runs out or I never leave this cave."
Jan 1, 2078: "Two months in cave. Still lethal outside. Don't get it. In army they said 2-4 weeks cleared fallout.
Jan 10, 2078: "Sounded like windstorm out there for 2 days. Radiation down 500. What happened?"
Jan 15, 2078: "Took a peek. Snow. It glows green."
Jan 28, 2078: "Radiation low enough I could risk short exposure outside. More important, cave stream now drinkable if I use Rad drugs."
Jan 30, 2078: "There is nothing alive out there."
So lets do the math. October 23, 2077 was the nuclear war. Jan 28, 2078 is when it was finally safe enough, so that's 97 days. Far short of 200 years.
Not true. watched a documentary about chernobyl recently and there are still levels of radiation around the area
Yeah I explained that. Chernobyl wasn't like an A-bomb going off. There was an explosion that tossed a crap load of radioactive nuclear fuel and material around. That is why its radioactive and even then alot of it is buried in the ground now and the plant life is uneffected.
When a nuclear bomb goes off the radioactive fuels gets used up to make the big Boom! and is then destroyed forever, it is transformed into verious radiations which then go away (become none lethal) after a couple months.
