Wh does recognise Ra-226 plates; second try

["Richard van Sonsbeek" <sonsbeek@wxs.nl>]

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.
