So from someone who had a high level waaaay back when...
Some people's physiology makes them more susceptible to soaking up lead more readily than others. I'm one of them.
There was a group of us that were shooting at a range called the Gunbarrel here in the 'springs years ago (the range no longer exists). Basically all of our exposure was identical. On a whim I got my lead level tested. It was very high. So high it triggered letters from the state saying, quite literally, that they were going to take my kids away if I could not identify and mitigate the source (fortunately, I have no kids). Sorry, I don't remember what the number was.
Everyone I shot with immediately got their lead levels checked as well. All were zero to near zero. It was only me.
So yhea, do everything you can to mitigate exposure - but still get tested every once in awhile.
O2 (or should I sign this "Pb"?)
