Tests people chose to run, not a random survey. Details on the York County radon levels page.
Basement readings versus first-floor readings
In ZIP 17302, basement tests have a median of 8.7 pCi/L, while tests taken on the first floor have a median of 3.9 pCi/L (41 first-floor tests). The basement number runs 2.2 times the first-floor number, which is the usual pattern: radon comes up from the soil, so it is strongest at the lowest level and gets diluted as it moves up through the house.
It also explains why two neighbors can get very different results. One tested a finished basement, the other tested a first-floor bedroom. For a decision about mitigation, the test that counts is the one from the lowest level anyone spends time in.

Most of the housing in Lower Chanceford Township went up between the 1940s and the 1970s (61.2% was built before 1980, median year 1974). That era mostly means poured or concrete-block basements. Block walls are hollow, and soil gas can move up through the cores, so a system here sometimes needs block-wall suction alongside the usual sub-slab point.
90.3% of homes in Lower Chanceford Township are single-family detached. A detached house with a basement is the easiest layout to mitigate: one suction point through the slab, a fan outside or in the garage, and a vent above the roof line. It is the standard sub-slab depressurization job covered step by step on our mitigation process page, and it usually lands in the middle of the cost range.
Cost-wise, most houses in Lower Chanceford Township are the standard $800 to $1,500 sub-slab job, with block walls or a second suction point pushing toward $2,500. Full ranges on the cost page.
