We did two charcoal tests a few weeks apart, 3.6 and 3.8 pCi/L. I misunderstood and did them both in finished basement where we don’t spend a ton of time. Because of allergies year around, we don’t open windows a lot although the basement laundry room window has been cracked since we moved in several years ago.

1. Do I need to retest on main floor? 2. Do we need remediation? Thanks in advance.

How often does it run? Is it disruptive?
