One piece of safety advice I got early on is simple: wash your hands after shooting. Wash your face too before eating. The ladies at the Wake County Ladies Handgun league mention this at every meeting.
If you shoot frequently, the lead exposure over time can add up. This is a simple way to address that issue for most shooters. If you work at a range or shoot daily, you may want to add lead testing to your annual physical. One of the instructors I’ve worked with does that. I may well ask for a lead test at my next physical to get a baseline for the future.
Much more information can be found here, on my favorite Shooting reference site, The Cornered Cat: http://www.corneredcat.com/article/firearms-safety/aiming-for-lower-lead-exposure/
