Lets assume if we were able to gather ALL the Radioactive waste on Earth, eg. depleted Uranium, and also other un-recyclable materials - drink bottles, plastic bags etc... and fire them into the Sun. Would then, the sun be contaminated for the next billion years since most radioactive materials have half-lives of millions of years. Or would there be NO effect at all? I've always been intrigued at possibility of using our sun as a waste storage system, but not sure about the consequences. Thanks!
