Fellow Radsafers:

I have a request from Singapore to identify items that might contain
radiaoctive materials  and likely to end up in scrap metal.  The following
is the actula message.  I can think  of a few like smoke dtectors.  But, I
don't know of a comprehensive list of such items.  If you have information,
please forward it to me at:

Thank you.
