There's a big scramble in the Department of Energy to preserve (and declassify, where possible) a lot of the data from the days of atmospheric testing, which is literally rotting. It's some of the only real world data we have on e.g. fallout dispersal, which is important for building the simulations that would allow emergency workers to safely operate in the aftermath of a nuclear attack. It's also of interest for nuclear forensics, which is highly relevant at the moment with the situation in Korea.
