>Dear Radsafers,

>I put a photograph on http://home.wxs.nl/~sonsbeek/home.htm

>Who does recognise these plates?
>
>They were found between lead scrap.
>
>Their size is about 10 mm x 15 mm x 1 mm.
>
>At the long side, the plates are bend.
>
>At the short side, the plates have small clamps.
>
>On one side they are contaminated with Ra-226. We estimate the original
>activity to be 2E+5 Bq(= 5 uCi).
>
>There is no equilibrium with Pb-210.
