Paul, you are absolutely right. 

The shileding windows of our hot cells are made from lead glass. The
thickness is approx. 1 meter. Before removal we have to discharge the
windows with a special device with thick cables from the manufacturer of the
windows.The manufacturer is Schott Glass in Mainz, Germany. They have an
english website with the following URL http://www.schottglasstech.com. Maybe
you can get additional informations there.

Hope this helps.
