any penetration of the floor or wall is a radon leak spot. think of 2
by 4s nailed or screwed to concrete floors, furring strips on walls,
all of these are totally inaccesible, behind drywall. and many cracks
will crack again.

the tiny ones you open up undercut, and seal.

but unless you fix moisture water issues all the time and effort and
money put into that spiffy new wood floor will be ruined in the first
major storm...
