Tile

Tiles are areas within Fallout: The Board Game that usually hold ruins, settlements, or enemy spawn locations. At the beginning of the game, all tiles, except spawn locations, are flipped over and unknown until a player uses an Explore action. If a tile has an enemy spawn location, an enemy of that type will spawn immediately.

Green tiles
Green tiles are usually safer than red tiles, and usually hold low leveled settlements and ruins.

Red tiles
Red tiles are dangerous tiles holding many high leveled creature spawn locations, higher leveled ruins and settlements, and processing more radioactive spaces.
