"Can that result in the kind of tumors and radiation sickness that normally occur with exposure to radioactive materials?" No. The level is pretty low. U-238 has a half life measured in billions of years. That means, over 4 billion years half of it would have decayed. And, when U-238 decays, it gives off alpha radiation, basically a helium nucleus, which aren't very dangerous. Granted, once it decays, the decay products have a much shorter half life. And some give off beta particles, which are fast electrons and more dangerous. But, still, there is never very much of them. health.state.ny.us
