Static-Master anti-static anti-dust brushes contained minute quantities of polonium 210 and were used to brush off vinyl record albums.
I probably have one or two of my late dad’s of that era stored with his hi-fi accessories.
It is obvious that the Russians were trying to make a statement. Almost any other method might have left questions about its origins. This message was that the Russian state killed this guy and they wanted it slow and painful. They also didn’t care if anybody else was cross contaminated in the process.
