I'm confused by that map. My childhood home is 10-30% of Maxmimum Radon potential but no idea how that relates to the absolute figures showing what the risk is.
Looking at that map shitloads of places are "Affected Areas". I never remember it being an issue round me when I was growing up, don't think anyone had sumps or whatever.
