I don't think lead levels are measured by ranges. Only the airflow output of the filters to make sure they're not clogged.
I also think the main exposure for lead during reloading is tumbling. It's one of the big reasons I haven't started.
Yep, tumbling dust exposure is my understanding as well. I won't run one inside. If that's an inhibiting issue for you, consider setting up the tumbler outside, or do wet tumbling.
If one were dumb enough to cast bullets inside without proper precautions there would be a strong likelihood of lead exposure.
Lots of hazardous materials exist in houses, and common environments. Most older houses have as original equipment things like asbestos, lead, mercury, etc. How those materials are managed defines the level of hazard they present.
