This "confirms" what I thought.

A review of the MSDS for Polonium 210 in ChemWatch indicated that
there is "no acute toxicological data identified in literature
search."  All of the exposure limits in the MSDS are based upon the
radiological exposure limits and the biological effects related to
radiation exposure.  For NFPA labeling it is classified as 2 for
flammability and instability and 1 for health.  Polonium
tetrachloride is similar with the exception of being a 3 for
flammability (spontaneous ignition in air) and a 1 for instability.

Seems like an a extremely inefficient way to kill someone to
me.  Maybe it was added as a contaminant to the real poison to
confound the investigation.
