Soldering contamination mainly comes from ingestion. Touching it, having small particles of lead burn off and land on your skin, then in your mouth (or eyes, elsewhere). Even so, by washing hands and wearing light PPE it’s fine. Because if that, many people consider the ban of industrial lead solder to be over-zealous. But that ban is in place to stop consumers being contaminated if they somehow touch the board. Also to minimise lead entering the water table once it is discarded.
