Free Radon Test Kits
The most popular radon test kits in the U.S. available at unbeatable prices!
You can even get one air test kit for free! State programs providing free radon testing kits to homeowners have all but disappeared. We can help a bit – if you also buy RadonSeal concrete sealer to seal your basement, the cost of the test kit is on us. You can buy RadonSeal up to two months later and we will issue a $14.95 rebate to your card. Limit - one free kit per customer!
For quick results, you can choose short-term air test kits. But since radon levels fluctuate wildly, long-term test kits will give you much more accurate results. If you have well water, test it because it may release lots of radon gas into the indoor air.
Free shipping by First Class mail in the US. Sorry, no shipping to New Jersey. Shipping to Canada is more expensive.
Everything is included!
There are NO HIDDEN CHARGES for testing, test reports, shipping, or otherwise. Compare that to radon kits sold in big-box stores: $9.97 per kit plus an extra $25 for testing, or $12.97 per kit plus an extra $10 for rush processing within 10 days which is "recommended" for valid results. (The half-life of radon is 3.8 days - after 10 days the results are not accurate.)
How to get a radon test kit for free!
Get an automatic $14.95 rebate if you purchase at least one 5-gal. pail of RadonSeal Deep-Penetrating Concrete Sealer within two months after purchasing the radon test kit(s). RadonSeal seals concrete basement floors and walls permanently against radon gas infiltration, water seepage, and water vapor. Compared to a radon fan mitigation system, sealing your basement with RadonSeal will save you over $1,000 on installation and operation. And it also seals against water and preserves the concrete.
If you purchase both on the same day, the rebate is issued automatically within a day. Or you can send us the Refund Coupon or email us as a reminder. Limit - one free kit per customer!
The fastest turn-around time!
Depending on your shipping options, you may get the results in one or two weeks after your order. Receiving the test results back in 3 or 4 weeks is common for other radon test kits.
Are short-term test kits worth it?
Radon levels fluctuate wildly and a short-term test is just a snapshot. Some argue that short-term test kits are worthless. Since radon levels fluctuate depending on weather and season, long-term test kits provide much more reliable results. Find out more at short-term vs long-terms radon test kits and what a homeowner should do.
When using short-term radon test kits, EPA recommends two side-by-side test kits for each location for most reliable results.
Radon gas causes lung cancer
Radon is an invisible radioactive gas produced by most rocks and soils. It is a single-atom gas whose atoms easily penetrate through openings in foundations, pores in concrete, drywall, paints or surface sealers, and even most plastics. Basements have the highest concentrations.
Radon gas is a very potent carcinogen and children are particularly susceptible. Among non-smokers, radon is the leading cause of lung cancer which is the #1 killer among all cancers.
Radon testing of all homes
Elevated radon levels have been found in every state. EPA recommends radon testing of all homes. Radon testing is essential before putting a house on the market to allow time for installing radon mitigation and before buying a house or before finishing the basement.
If you have a private well, test the radon level in your water with the radon-in-water test kit. Showering, cooking, dishwashers, and washing machines release radon gas into the air. As a rule of thumb, each 10,000 pCi/L in water contributes 1 pCi/L to indoor air.
Repeat the radon test once a year!
Concrete becomes more porous over time, joints or cracks open up, and underground flows of radon shift. Whether or not you have a radon mitigation system, your radon level might increase dramatically. Radon test results are considered invalid after two years. EPA recommends that homeowners repeat the radon test regularly.
Test the radon level in your home about once a year! Radon test kits are inexpensive and your family’s health is at stake.
There is no "safe" radon level
EPA's recommendations to homeowners:
However, EPA warns that there is no "safe" radon level! The Radon Act has set the target radon level in homes much lower at 0.4 pCi/L.
If you just settle for 4 pCi/L, your home will be more radioactive than 94% of U.S. homes. The lung cancer risk to each member of the family is equivalent to smoking 8-10 cigarettes a day.
The vast majority of radon-induced lung cancers occur in homes with radon concentrations below the 4 pCi/L "Action Level."
Radon mitigation options
Reduce radon in your home to a "reasonably achievable minimum"! You can get a fan-based radon mitigation system, which exhausts the heavy radon gas above the roof.
Or you can avoid the noisy radon fan and unsightly piping by sealing the basement using the RadonSeal radon mitigation method. It saves lots of money on installation and operation, and does not depend on the the reliability of equipment or the power grid.
