Bad news, skippy. Polonium has no stable isotopes and is highly radioactive. It's generation and distribution are controlled by the Nuclear Regulatory Commission. Ya can't just thumb through the nuclear goods catalog and order some up. The good news is that you can probably acquire some on the Russian black market. And it's probably cheaper than here, plus there's no "red" tape. (Couldn't resist that.) Just to answer your question, it is possible to acquire a "needle source" of Po for your own "research" purposes without a lot of license requirements. But the quantity is soooooo small that it's actually plated onto something you can manipulate and is waaaaay less than would be visible with the naked eye. A couple of hundred bucks would cover your "project" costs, but this stuff is hot. Be straight on this one. You can get dead fooling around with this stuff. It's really nasty. It's the poison used to murder Alexander Litvinenko. Please direct your curiosity at something "good" and useful and that will make you some money and benefit you, your family and your community. Oh, and don't forget to read about the famous "physicist" David Hahn. A link to the Wikipedia article on this guy is provided. He has a frightening need to play with radioactive substances, and the picture of him in the post (a mug shot of him taken because he was stealing smoke detectors to disassemble them to recover radioactive americium) might convince you that radioactive materials are dangerous. Check this out if you only check out one thing. As a p.s., it is a known fact that determined people who are making inquiries to satisfy their own curiosity are going to get the information where ever it may be and by whatever means necessary. David Hahn is a prime example. The information in the answer here is supplied with the idea that in getting answers in this place, a curious person will also get a good idea of the down side to pursuing a line of investigation. The down side here is that one can end up with radiation poisoning if one pursues obtaining polonium. (And others may be exposed. Usually family and friends.) The radiation poisoning may not kill for some time, as with Marie Curie. But a foolish investigator will end up a dead man walking. David Hahn is just such a man.

Polonium ( /pɵˈloʊniəm/ po-LOH-nee-əm) is a chemical element with the symbol Po and atomic number 84, discovered in 1898 by Marie Skłodowska-Curie andPierre Curie. A rare and highly radioactive metalloid,[1] polonium is chemically similar to bismuth[2] and tellurium, and it occurs in uranium ores. Polonium has been studied for possible use in heating spacecraft. It is unstable; all isotopes of polonium are radioactive.I think you might be referring to Palladium, which is a precious metal like gold or silver. At the moment Palladium is worth app. $640 per troy oz, or $32 per gram. Their are 20 grams in a troy oz.
A lot. Isotopic copper ranges from 1,300 to over 3,000 euro per gram.
