My 5 & 2 yr old & myself were briefly (less than 5-7 mins) exposed to airborne granite dust yesterday, is this any cause for concern? paranoid momma

Relax: Please don't be a "paranoid mamma"! If this is not causing any concern now it is very unlikely to have any problems.

Can't think of a pbm: There are many agents we never want to be exposed to, like chlorine gas/radiation/asbestos etc. However, granite has no such implication that I can think of. I consider it big dirt, which kids seem to attract like a magnet.
