I've stripped woodchip wallpaper with lead paint on it. I think I have all the dust in my carpet and furnitre. What do I do?
What can I do?

You could get a sample tested for lead. For example there is a 3M product called LeadCheck.

From what I've read: in the UK, lead-based paint was mostly used on woodwork. The relevant Wikipedia article suggests this. lead chromate was not used on walls after the early 1970s.
