# Radon has been found in every part of Vermont.

One in seven Vermont homes has elevated levels of radon.[^1] You can’t see, smell or taste it, so testing is the only way to know if it’s in your home.[^1]

## Where are you with radon?

- [I want to test my home](https://vermontradon.com/how-to-test/) Which kit to use, where to put it and how long to leave it.
- [I have a test result](https://vermontradon.com/understanding-results/) At 4.0 pCi/L or higher, contact a certified mitigation contractor; between 2.0 and 4.0, consider mitigation.[^3]
- [My result is high](https://vermontradon.com/find-a-contractor/) Radon problems can be fixed. The most common system is estimated at $1,500 to $2,500 installed.[^3]
- [I’m buying or selling a home](https://vermontradon.com/buying-or-selling/) What Vermont law requires, and quick tests for a sale.
- [I’m on a well or spring](https://vermontradon.com/well-water/) How to test your water and what the advisory level means.
- [I want my town’s numbers](https://vermontradon.com/towns/) Health Department test results for every Vermont town, city, gore and grant.

## Radon in every Vermont town

Each town is shaded by its share of results at or above 4.0 [pCi/L](https://vermontradon.com/radon-glossary/#pci-l).[^4] Select a town for its numbers.

15%

of 26,805 Vermont locations tested with Health Department kits had radon at or above 4.0 pCi/L.[^4]

About this map and its numbers

Statewide: 4,069 of 26,805 results, calculated by Vermont Radon from the Health Department’s town data, retrieved October 17, 2026. Map: share of tested locations at or above 4.0 pCi/L, by town, in Vermont Radon’s grouping of Health Department data.[^4] Boundaries: VCGI.[^5] **Important:** A town’s numbers can’t predict any one home’s level: neighboring homes can have very different radon levels.[^1] The only way to know is to [test your home](https://vermontradon.com/how-to-test/).

## Start here: the recommended test

Order the Health Department Lab’s $25 long-term kit[^6] and leave it out 3 to 12 months, ideally through a heating season.[^1]

A [digital monitor](https://vermontradon.com/radon-glossary/#cdrm) is optional: it adds day-to-day readings.[^7]

Use a monitor alongside the kit, not instead of it: the Conference of Radiation Control Program Directors (CRCPD) says to check its results with an approved test.[^8]

## Common questions

### Is radon a problem in Vermont?

Yes. One in seven Vermont homes has elevated levels of radon, according to the Vermont Department of Health.[^1] High radon levels have been found in all types of homes in every area of Vermont.[^9]

### What radon level is too high?

At or above 4.0 pCi/L, the Health Department and EPA recommend reducing radon in your home, and they encourage action to get below 2.0 pCi/L.[^1]

### How much does it cost to fix radon in Vermont?

The Health Department estimates $1,500 to $2,500 to install [active soil depressurization](https://vermontradon.com/radon-glossary/#asd), the common vent-pipe-and-fan system for radon in air.[^3]
