Bottom line you should be concerned. Me and 4 other people all tested very high on lead. All from the same indoor gun club.
One guy had to have transfusions to get his level down. I had to take meds and stay off the range for 6 months.
Using a brass cleaner indoor is also a huge source of lead and can hurt your entire family.
If you are serious go to your doc. for a simple blood test.
And BTW--- the older gun clubs have all been grandfathered from the laws governing air flow etc and DO REPRESENT A SERIOUS THREAT.
