Don't disagree with me, disagree with the half life of radioactive compounds.
The three factors for protecting oneself from radiation and fallout are distance, shielding, and time.
Distance - the more distance between you and the fallout particles, the better. An underground area such as a home or office building basement
offers more protection than the first floor of a building. A floor near the middle of a high-rise may be better, depending on what is nearby at that
level on which significant fallout particles would collect. Flat roofs collect fallout particles so the top floor is not a good choice, nor is a floor
adjacent to a neighboring flat roof.
Shielding - the heavier and denser the materials - thick walls, concrete, bricks, books and earth - between you and the fallout particles, the
Time - fallout radiation loses its intensity fairly rapidly. In time, you will be able to leave the fallout shelter. Radioactive fallout
poses the greatest threat to people during the first two weeks,
by which time it has declined to about 1 percent of its initial radiation
Continuing on.... It does have to do with the blast, so you are right...
After a Nuclear Blast
Decay rates of the radioactive fallout are the same for any size nuclear device. However, the amount of fallout will vary based on the size of the
device and its proximity to the ground. Therefore, it might be necessary for those in the areas with highest radiation levels to shelter for up to a
The heaviest fallout would be limited to the area at or downwind from the explosion, and 80 percent of the fallout would occur during the first 24
People in most of the areas that would be affected could be allowed to come out of shelter within a few days and, if necessary, evacuate to unaffected
