Residential Radon Gas Testing – Mold and Indoor Air Quality Inspection by ScanTech Technical Consulting

Radon is one of the leading causes of lung cancer

Radon is one of the leading causes of lung cancer in the United States

In a rush to test your home for radon gas or radioactivity in natural stone such as granite or marble? Did you know that radon is the 2nd leading cause of lung cancer? (Smoking is 1st and radon gas synergistically increases mortality rates for smokers)

While it is not well known, radon gas levels EXCEED EPA action limits of 4 picoCuries/liter (pCi/L) in up to 10 % of all homes in Dallas county with an additional 14 % falling into the marginal range of 2 – 4 pCi/L. This means that 1 out of 4 homes (10 % + 14 % = 24%) in Dallas either have a radon issue or fall into a caution category. Other counties, such as Tarrant, Collin and Denton are not immune either. (see the link below on Radon FAQ from ScanTech for more details)

Example areas of the Metroplex (not a complete or comprehensive list) which have been found by ScanTech testing to have excess radon levels which are statistically higher than the 24 % quoted above include:

  • North Dallas and Far North Dallas
  • Lake Highlands
  • University Park
  • Highland Park
  • Park Cities area
  • Richardson
  • Arlington

ScanTech now has the capability to test and get results within as little as 24 hours of initial deployment using a high quality digital tester in case your option period is about to expire.

Our services are both faster and cheaper than competing methods or companies and we have been performing radon testing for homeowners in the DFW area for over 10 years.

Testing is performed by an engineering graduate experienced in radioactivity measurements,  indoor air quality testing including mold inspection, formaldehyde and radon gas testing.

AARST NRPP National Radon Testing Professional Certified

Radon Gas Testing Methods & Equipment

There are a variety of ways to monitor the radon levels in a residence, home or commercial building and the best detector for your needs depends on balancing cost, accuracy, ease of use and type of application such as a long or short term test.

The chart below gives a comparison of different detectors including the time period duration during which radon is measured.

Radon & Radioactivity Measurement Safety Guide

Measuring radioactivity from radon is potentially very confusing for the lay person for several reasons. One of which is that there are several different units of measurement depending on the application, era of standards and preference based on world regionalisms. Applications include activity, (which radon measurement falls under) absorbed dose, which is the measure of radioactive energy absorbed by tissue per unit mass and dose equivalent which is the measure of absorbed doses from DIFFERENT types of radioactivity such as alpha, beta, and gamma radiation. Many scintillation meters still measure this in the older measurement unit rem (Roentgen Equivalent Man) or microrems for gamma radiation.

For instance, when measuring radon, North America prefers to use the picoCuries per liter (pCi/L) designation as opposed to Becquerels  or Bq / meter^3 which is typically used in Europe and the UK. These both measure a specific number of atomic disintegrations per volume of space.

In the case of the Becquerel, this is 1 atomic disintegration per second or 60 events per minute. For a picoCurie, this is translated as 2.2 radioactive disintegrations per minute. A convenient conversion chart is shown below.

Just as a quick conversion from the picoCurie/liter to the Becquerel / m^3:

1 picoCurie / liter = ~ 37.1 Bq/m^3     EPA action limit 4 pCi/L = ~ 148.4 Bq/m^3

Units of Measurement for Radioactivity and Dose

Units of Measurement for Radioactivity and Dose

As an added note, a little known unit of radon is what is known as a Working Level (WL) which is the quantity of radon that will produce 1.3 X 10^5 MeV (Mega Electron Volts) of potential alpha particle energy per liter of air. A single WL of radon is equal to the RDP’s (Radon Decay Products) in equilibrium with 100 pCi/L of radon. Because the equilibrium value for RDP’s for indoor environments is typically 0.5, radon concentrations of 1 WL would be around 200 pCi/L.
