About JoCo Radon

What this site is, how the referral works, and why every number on it has a source next to it.

What this site is

JoCo Radon is a radon information and referral service for Johnson County, Kansas. This site connects you with KDHE-certified radon measurement and mitigation professionals in your area.

When you call the number on this site, you reach us, and we connect you with a certified local professional who does the measurement or the installation. We are not the crew that shows up at your door, and we would rather say that plainly on an About page than have you work it out later.

Why every claim here has a source

Most radon pages you will find for this area repeat numbers with no attribution, and some of them are wrong. We checked one competitor page that described a 1957 tornado as hitting Olathe with 207 injuries; the actual event tracked 71 miles from Williamsburg into Missouri and the injury figure was over 500. That is the standard in this category.

So every figure on this site — the 5.3 pCi/L county average, the 41% of Kansas tests above the action level, the $8–15 test kit price, the certification law dates — is attributed to a government, university, or agency source you can open and read. If we could not source it, we left it out.

What we will tell you that a salesperson will not

  • Test cheaply first. A DIY kit from the Johnson County Extension office costs about $8–15. For most homeowners that is the correct first step, and paying anyone for a first-pass screening test is wasted money.
  • Check for existing pipe. If your home already has a capped passive radon stack, you need a fan, not a system. That is a much cheaper job and you should be told so before being quoted.
  • Check your manometer. If you already have a system and the liquid sits level in both columns, the fan has failed and the radon is back. Nothing alerts you to this.
  • Verify certification. Ask any contractor — including whoever we connect you with — for their KDHE number, and verify it at 785-296-1560.

Certification in Kansas

The Kansas Radon Certification Law was passed in 2010, effective 2011. It requires current KDHE certification for radon testing or mitigation performed for hire, in two years terms, and Kansas accepts NRPP or NRSB national credentials. Statute K.S.A. 48-16a10 requires certified contractors and laboratories to report measurement data to the state quarterly.
