Dear Cindy,

I don't have an anwswer to your question about lead sheets.   But I want to
tell you a funny story.  Many years ago (30+) I attended a lecture at Yale
about radiation and the measures that should be taken to guard against it
in the laboratory. The speaker (who shall remain nameless) had a very heavy
accent, but he was very well known, and the audience paid great attention.


He went on about how to position these items in the wall--the thickness and
the height--to guard against the problem.   We all came away fully prepared
to install dead sheep (!) wherever and however they were necessary!

Pity the poor children!
