That's a terrible story. I am so sorry for what your uncle has had to suffer. I think there is a safe limit. When I did a number of shooting sports I got myself tested. I was absolutely fine, despite almost certainly inhaling small amounts of leads, and definitely handling lead. I have only met one person in the shooting sports/shooting industry who was diagnosed with lead poisoning, a young woman who worked at a gun store/range. Many people who I shot with would have had far greater exposure than me and also got themselves tested. The counter argument is that lead poisoning has such a wide range of symptoms it can be misdiagnoses.
