What is Radon?

Radon, is a radioactive, odorless, colorless, tasteless, and chemically inert gas that was first discovered in 1910. Radioactive elements in rocks find their way into the soil as they are worn down over time, and in certain instances, can migrate through soil to enter homes in quantities that are great enough to be a hazard to your health.

In order for these instances to occur, there must be a source of radon, permeable soil, and a conduit into your house. The most common points of entry include, but are not limited to, porous basement floors/walls, cracks in concrete floors or slabs, and openings around utility accesses.

Certain areas are susceptible to radon accumulation as well:

  • Buildings constructed in areas where the rocks contain higher than average quantities of uranium
  • Buildings that are created over uranium-bearing veins and granite pegmatites
  • Geographic areas containing radium contamination
  • Property in areas that contain high concentrations of radon in the ground water
  • Residential or commercial buildings built on or constructed with radioactive materials like as uranium mill tailings.

Houses built in other areas of the Piedmont Province, especially those built on the zone of phyllites running through central Montgomery, western Howard, eastern Frederick and central Carroll Counties, frequently have indoor radon values exceeding the levels considered safe by the Environmental Protection Agency.

How do I know if I have a radon issue?

Testing for radon is the only way to know if you are at risk. Many methods are available to detect radon, but the two most popular with homeowners are the carbon canister and the track etch. These devices are placed in either your basement or your living area for a specific amount of time before being returned to wherever they were purchased for analysis.

Measurements can also vary with both the location in your house as well as the season, so to get the best assessment, multiple readings should be taken at different times. Readings taken in the basement during the winter are often found to be the highest.

How to interpret test results?

No level of radon exposure is technically safe. However, if your long-term exposure will average 4 picocuries per liter (pCi/L) or higher, the EPA recommends taking action to reduce it. pCi/L measures the rate of radon’s radioactive decay, where 1 pCi/L is one trillionth of a curie, 0.037 disintegrations per second, or 2.22 disintegrations per minute.

Therefore, at 4 pCi/L (the EPA’s recommended action level), there will be approximately 12,672 radioactive disintegrations in one liter of air during a 24 hour period.
