Actually, if you can get some uranium and break into a doctors office, you could make plutonium from it.
Also, plutonium may be radioactive, but guess what? It is not going to kill you, the radiation when it is not undergoing a nuclear reaction is very minimal. Although the substance itself is toxic for other reasons, if you injest it. But just its normal decay is harmless, and so is that of uranium.
And don't try to say the Curie's died of it, they were doing expiraments and were accelerating the decay rate and causing small scale reactions. Of course they would have more exposure, it wasn't normal decay. (I have held in my bare hands a peice of U-238, about 85% pure) Guess what, it didn't do anything to me, I held it for about 15 minutes. Heck it couldn't even get rid of my warts.
There is more radiation coming from your monitor than from a peice of uranium when its decaying naturally.
Radon is the same way, its radioactive yes, but when its naturally present it decays at a slow safe rate. Even in radon mines where it radon gas is in higher concentrations are safe, and you recieve about the equivelent of 2 xrays every day in a radon mine. Why do you think people pay money to sit in radon mines? Because the radiation kills bacteria and virii, which makes people healthier.
Okay, end of rant. I just get so sick of enviromentalists saying that radiation in any amount is going to kill you. Heck, did you know that YOU ARE RADIOACTIVE?
