We offer professional radon measurement with the 1028 Sun Nuclear Continuous Radon Monitor. Test results include a grahical representation of the radon concentration for every hour deployed, along with overall and US EPA average readings.
Tests run for a period of 48 hours, and same day appointments are often available. Continuous radon monitor tests are a great way to get the most accurate measurements available. Please let us know if your home has a crawl space or room addition.
St. Louis Radon's monitors are calibrated annually by an EPA approved laboratory. They're also subject to QC/QA program and continuously checked throughout the year to verify accuracy.
CRM machines have tamper resistant features that detect device movement.
Radon Test Results - Example 1
Radon Gas in Missouri
The US Surgeon General strongly urges everyone in the US to test for Radon gas.
Levels between 4-20 pCi/l are very common. Homes are only occasionally far above 20 pCi/l, however we have fixed Missouri homes with continuous spikes over 80 pCi/L. It would take approximately 2,500 radon atoms per square inch to create a radon concentration of 4pCi/L.
You cannot estimate radon levels based upon the homes age, location, design or test results from a neighbor's home.
- There are no symptoms from radon exposure.
- You can't see radon.
- And you cannot smell it or taste it.
All homes should be tested in a real estate transaction, regardless if they have a radon reduction system. Homes with radon systems should be retested at least every two years.
Radon is measured in PicoCuries per Liter of Air, (pCi/L). Pico = one trillionth.
1pCi/L = 2.22 decays per minute per liter of air. So then, 4pCi/L equals 10 decays per liter of air per minute.
Testing is the only way to know.
About 1 in 15 homes across the United States is estimated to have Radon levels exceeding the EPA's action level. One in every 5 homes in Missouri are believed to be above the acceptable EPA limit. The only way to know if a home has a problem with radon gas is to test.
