short-term radon test in Readington Township usually starts with a number somebody was not expecting.
What usually prompts the call
- A previous test was done years ago and you have since changed the heating or the ventilation
- You finished a basement and want to know what you have been sitting in
- A neighbour tested high and you have never tested at all
Why this comes up in Readington Township
Outside the village systems this is largely well country. A Readington well draws from Passaic shale, or from the Cushetunk diabase at the reservoir end — two quite different aquifers inside one township.
Readington Township — the state's own numbers
40% of the 4,041 test results NJDEP holds for Readington Township were at or above the 4.0 pCi/L action level — 1,635 of them. That puts it in Tier 1 — high potential.
Preserved farmland and farmsteads alongside large-lot residential development, with several distinct historic villages.
What access looks like here
Open rural lots with ample room; older farmsteads can be more constrained.

How it's normally done
A short-term test means a sealed-house condition for at least 48 hours with a continuous monitor or a pair of charcoal detectors placed at the lowest lived-in level. The house has to stay closed the whole time, which is the part that most often invalidates a result. In New Jersey the placement and the reading both have to be done by a certified measurement business for the result to count in a real-estate transaction.
Typical cost in Hunterdon County, NJ
$150 – $325 — typical range, not a quote. What your building needs can only be settled by a certified business that measures it on site.
Local experience matters here — the ground under Readington Township does not behave like the other end of the county.
New Jersey requires certification for this
Measurement is certified separately from mitigation. Under N.J.A.C. 7:28-27, testing for radon for a fee in New Jersey requires NJDEP certification as a radon measurement business. A crew certified to install systems is not thereby certified to place and read the detectors. We only route this work to businesses we have checked on the measurement side.
