- I wondered the same thing when I was making tens of thousands of solder
- joints (literally) as part of a prototype production project at a local
- university. I won't tell you which, but they do have a terrific men's
- basketball team. The occupational health office finally agreed to give
- me a blood lead test, and found the level to be lower than the national
- average.
-
- This was somewhat surprizing, until the doc pointed out that it is
- probably the flux that creates the bulk of the vapors which we all
- inhale some of. The solder itself doesn't vaporize until you get it
- REALLY hot, which is why the guy at the radiator repair shop seems so
- unusual. The main source of blood lead in the average American is from
- car exhaust. You probably get a higher chronic level of lead exposure
- from driving around and filling the tank of your car than you do from
- all the soldering you will ever do (as a hobbyist, anyway). When you
- read "unleaded" gas, think "decaffienated" coffee.
-
- What I would recommend is to use the lead-free solder from Radio Shack
- that you mentioned (they are good for SOMETHING, if your not too
- paranoid to reveal your name), don't hold the solder in your mouth
- while you have both hands on your work (I have seen people do this),
- put a small fan blowing across the workbench to disperse the smoke, and
- make sure you wash your hands between soldering and eating, drinking,
- or smoking. Should be normal for the rest of your life!

- Good Luck,
