You would not be able to administer this form, as it is an active metal. Remember, it is only ~10 micrograms, not readily handle-able. The handle-able form is a solution, for small amounts. And as for tort lawyers, Po210 emits a characteristic gamma ray, and this would be the type of evidence that would have to be presented in court to prove actual exposure. The amount of characteristic gamma ray emission would tell the amount of exposure, and a comparison then would be made to the background amounts in people.
