You might end up with one of those ventilating blowers with PVC pipe stacks running up the side of your house if done after the build as a fix.
This is typically a specialty item/installation, perhaps there is a way to run the PVC pipe vent inside a wall if that meets your state code.
You might be able to vent a slab for Radon the way they do for Methane (people do build on old landfills), but again you need to talk to an installer or code official about this.
Our Michigan Building Code here is based on the International Code and has a special Radon Chapter. Now might be the time to look at your code and start talking to someone local about it.
EDIT: regarding mold and concrete ground slabs..............a crawl is looking better all the time. I know that for commercial concrete counter-tops/bars in food service areas there are several additives which prevent the build up of germs. Just a wild thought and deserving of some research, perhaps there are
additives in addition to the traditional vapor barriers and rigid insulation (never use expanded beadboard (white), use only extruded polystyrene pink/blue) which can be used on a ground slab in your area.
