I wonder if lead sheeting is used in areas where X-ray operators duck behind
a screen or barrier.
Yep. A friend's dentist did a new installation and friend was able to salvage a sizable chunk of ~1/16" thick sheet lead which he was kind enough to share. Also a boxful of ~ 1"x2" pieces of lead foil which are part of those cardboard encased pieces of x-ray film with the bite tab they tell you to chomp on when they stick them in your mouth. This stuff mashes into odd-shaped spaces very nicely. Dentists typically save the lead foil for recycling (since it shouldn't be put in the regular trash). Would your dentist give it to you instead? - You can ask! Good Lift!
