No problem. You're not going to get yourself killed by being overly cautious. Besides, there's just something fun about going into your stash, grabbing a big wooden box that weighs a LOT, then opening it up and seeing yet another lead box inside of there, then opening that up and taking out a vial of about half an ounce of Uranium metal. It's very 'atmospheric' and creates quite the shock when people see it. I typically 'admire' my uranium sample at most once a month for a few minutes. Nothing longer than that. While the radiation is weak, it is radiation.
