OK, I know the likelihood that those of us who were on these flights got infected is very low, but IF we were infected with polonium, what should we do as treatment? Is there actually anything we can do about it? Please answer if you know for sure.

I did a lab, but I can't figure out what was made in the reaction because there are so many possibilities. Magnesium was put into a crucible and reheated many times until no reaction (the Mg strip burning or lighting up) was made. Of course, air is not only oxygen. It also has nitrogen in it so it also could have made a different formula than MgO. So what is the formula for this compound?
Also, it was later grounded up and put with water, then burned again until a small vapor came up. This also might have created a new compound, and I have no idea what it is other than MgO with H2O molecules. Any help would be appreciated.
