so u mean u cant fire guns with out knowing ur being poisoned?
Goodness gracious.
You can can fire guns without knowing a lot of things (like spelling and punctuation). You can also poison yourself in many ways (not using guns) without knowing it. I'm guessing, however, that what you wrote is not what you intended to ask. I suggest you reread my posts in this thread.
1) There is a difference between being exposed to some lead and being "poisoned." Many, many compounds are "poisonous" at high exposure levels, but innocuous at low exposure levels.
2) There is a difference between a well-designed, well-ventilated indoor range and a poor one.
3) You would not want to let your child play on the floor of an indoor range, particularly downrange of the firing line.
4) Most airborne lead at shooting ranges comes from two things: a) if the base of the bullet is exposed lead, then a small portion of the base is vaporized when the round is fired, and b) lead compounds in the primer that vaporize when the primer is discharged.
5) You can reduce the amount of airborne lead by using bullets that have a jacket covering the base, like JHP, TMJ, or plated bullets. Note that FMJ bullets are NOT jacketed on the base.
6) Frangible, non-toxic rounds do not have lead in bullet or in the primer, so they do not contribute to airborne lead. However, they are significantly more expensive than rounds containing lead.
7) Any decent NRA safety course will cover standard hygiene recommendations that will help reduce your exposure.
8) The NSSF has monographs on this subject.
9) Your exposure to airborne lead is generally less at outdoor ranges than indoor ranges.
