Sorry to hear that about your family.I've got a jar with a lot of marbles in it . How does a person find out if they are with Uranium ? I hope I don't have any ! My uncle owned stock in a Uranium mine and had a big chunk of it sitting on his fireplace mantle for years for everyone to gander at ! He died from Cancer. My dads older brother had a copper burst plate from a test in Nevada and it was a "used" part bowed out and used as a ash tray for many years. He also died of Cancer. My younger Brother finally got that Burst plate and had it in his garage shelf for a long time and don't remember what happened to it ! It was about 6-8 inch's in Diameter and the bolt holes were ovaled out and the middle of it was dished out big time ! Makes me wonder !!
