Radon Testing

The U.S. Environmental Agency (EPA), the U.S. Surgeon General, and the Centers for Disease Control (CDC) all strongly recommend that every homebuyer have an indoor Radon test performed prior to taking occupancy.

Radon is a naturally occurring, colorless, odorless, radioactive gas. Radon concentrations vary based on the geological conditions of the area. Radon enters the home through various means and collects inside.

Radon is a Class A human carcinogen. The EPA and the Surgeon General estimate that Radon is responsible for more than 21,000 deaths annually, making it the leading cause of lung cancer among non-smokers.


Radon levels are considered to be high in Colorado.

According to the Colorado Department of Public Health and Environment, about half of the homes in Colorado have Radon levels higher than the EPA recommended action level of 4 picocuries per liter (pCi/L).

Accurate results can be achieved with a 48 hour test.

Fisrt Summit Home Inspections Radon Test

All homes should be tested regardless of geographic location or foundation type. The test process is easy. We use SunRadon 1028-XP Continuous Radon Monitors. A monitor is placed in a carefully chosen location and run for 48 hours.

Tamper Detection
The monitors we use are upgraded to track Temperature, Humidity & Barometric Pressure. This, along with built-in motion detection helps us to identify any efforts to tamper with the location of the monitor or the environment (opening windows, running fans, etc.) during the test. This way you can be confident in the results you receive.

Once we retrieve the monitors, the information is downloaded and compiled into an easy to read report. After that, we will meet to discuss the results and the EPA’s recommendations based on your results.


Colorado does not require certification for Radon testing. So, not all companies offering testing adhere to equal levels of proficiency and quality control. The National Radon Proficiency Program (NRPP) is recognized by Federal Agencies and required by some State Radon programs. NRPP credentials indicate to homeowners and agents that we have the skills and equipment required to provide accurate Radon testing. We are NRPP certified (ID#111641-RT) as a Residential Radon Measurement Provider. Visit www.nrpp.info for more information.

The process to become NRPP certified is rigorous. It includes the following:

  • Complete an NRPP approved training course and pass a proctored exam
  • Use and register only approved test devices
  • Test a device against a known amount of Radon at an approved facility
  • Maintain a Quality Assurance Program
  • Meet Continuing Education requirements
  • Send equipment to an approved facility for annual calibration
  • Adhere to the NRPP Code of Ethics
