Probably not. All isotopes of Polonium are radioactive, making it very
inconvenient to work with. In addition, Po is unlikely to form compounds
with Na of the given stoichiometry. Further, Po is way too expensive to
use its compounds merely for buffering.
However, if you mean Na2HPO4 than that is a very common chemical known as
Disodium hydrogen phosphate, which indeed can be used to make buffers.
Check the catalogs of supply companies like Fluka, Riedel or Merck.
Of course my answer is a little tongue-in-cheek, but I wanted to
emphasise the importance of correct scientific terminology.
