Digest topic: Radioactivity testing

My laboratory uses a dilute aqueous solution of Thorium nitrate in one of its processes. Thorium nitrate is considered weakly radioactive. A request has been made for us to obtain information regarding the specific radioactivity of the solution. Does anyone know of a laboratory that will perform certified radioactivity testing? We have been unable to find a laboratory to help us!

Thank you for any help you can provide!

Janine
