Does anyone recognise these Ra-226 plates?

Dear Radsafers,

Does anyone recognise the items on the attached photograph?

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.
