Re: And the heavy blanket put over your chest when the dentist takes xray pictures?

does it have a name besides a lead (as in the metal) blanket?
My destist used to have one, labeled Brand X (i forget the brand) lead blanket.

i suspect is either has a thin sheet of lead foil, or is quilted with lead wool-- which is very similar to steel wool. In my youth, lead wool was used to fill up holes created by rodents, before they were plastered over.. if the mouse/rat/squirrel tried to eat their way through again, they got lead poisoning and died.
oh, the fond memories of a dickensian childhood!
