Short-term radon test in Lebanon Township

Lebanon Township owners ask about short-term radon test more than you would think for a town this size.

What usually prompts the call

• A neighbour tested high and you have never tested at all
• A buyer or a lender has asked for a radon test before closing
• A previous test was done years ago and you have since changed the heating or the ventilation

Why this comes up in Lebanon Township

Public supply reaches very little of this township. Where an address is on a private well, that well draws from the same fractured Precambrian gneiss and granite that produces the soil gas — so the water is a second question, not the same one.

Rural and semi-rural, from 18th and 19th century stone farmhouses to 1970s-onward houses built on cut-and-fill lots carved into the hillsides. Full basements are common because the ground had to be excavated anyway.

What access looks like here

Long driveways, sloping lots and plenty of room around most houses, so exterior pipe routing is usually straightforward.

Construction permits go through Lebanon Township, and installing radon mitigation for a fee anywhere in New Jersey requires NJDEP certification.

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.

The sooner it is measured, the more of the options stay open.
