Keeping A Healthy Home

Radon & Air Quality Testing

A Healthy Home Is A Good Home

A Real Estate Inspection Inc. believes that a general home inspection is only half the inspection required for you new home. A general home inspection is only good for what is visually seen. Now you should consider what you are not seeing and read the facts stated below:

What is Radon?

Radon is a cancer-causing radioactive gas. You cannot see, smell or taste radon, but it may be a problem in your home. The Surgeon General has warned that radon is the second leading cause of lung cancer in the United States today. If you smoke and your home has high radon levels, you’re at high risk for developing lung cancer. Some scientific studies of radon exposure indicate that children may be more sensitive to radon. This may be due to their higher respiration rate and their rapidly dividing cells, which may be more vulnerable to radiation damage.

A Scientific Description

PROPERTIES: Radon is a gaseous highly radioactive element discovered by English physicist Ernest Rutherford in 1899. The discovery is also credited to German physicist Friedrich Ernst Dorn in 1900. More specifically, Rutherford discovered radon’s alpha radiation and Dorn discovered that radium was releasing a gas.

Radon is a colorless chemically-unreactive inert gas. The atomic radius is 1.34 angstroms and it is the heaviest known gas–radon is nine times denser than air. Because it is a single atom gas (unlike oxygen, O2, which is comprised of two atoms) it easily penetrates many common materials like paper, leather, low-density plastic (like plastic bags, etc.) most paints, and building materials like gypsum board (sheetrock), concrete block, mortar, sheathing paper (tar paper), wood paneling, and most insulations.

Radon is also fairly soluble in water and organic solvents. Although reaction with other compounds is comparatively rare, it is not completely inert and forms stable molecules with highly electronegative materials. Radon is considered a noble gas that occurs in several isotopic forms. Only two are found in significant concentrations in the human environment: radon-222, and radon-220. Radon-222 is a member of the radioactive decay chain of uranium-238. Radon-220 is formed in the decay chain of thorium-232. Radon-222 decays in a sequence of radionuclides called radon decay products, radon daughters, or radon progeny. It is radon-222 that most readily occurs in the environment. Atmospheric releases of radon-222 results in the formation of decay products that are radioisotopes of heavy metals (polonium, lead, bismuth) and rapidly attach to other airborne materials such as dust and other materials facilitating inhalation.

EXPOSURE: The primary routes of potential human exposure to radon are inhalation and ingestion. Radon in the ground, groundwater, or building materials enters working and living spaces and disintegrates into its decay products. Although high concentrations of radon in groundwater may contribute to radon exposure through ingestion, inhalation of radon released from water is usually more important.

Should you test for radon?

Testing is the only way to know your home’s radon levels. There are no immediate symptoms that will alert you to the presence of radon. It typically takes years of exposure before any problems surface. The US EPA, Surgeon General, American Lung Association, American Medical Association, and National Safety Council recommend testing your home for radon because testing is the only way to know your home’s radon levels.

Radon is a national environmental health problem. Elevated radon levels have been discovered in every state. The US EPA estimates that as many as 8 million homes throughout the country have elevated levels of radon. Current state surveys show that 1 home in 5 has elevated radon levels.

Can you fix the problem?

If your home has high concentrations of radon there are ways to reduce it to acceptable levels. Most radon problems can be fixed by a do-it-yourselfer for less than $500. If you want or require the assistance of a professional you may wish to look at the list of certified radon mitigators for your state.

Why Is Indoor Air Quality Testing So Important?

The quality of the air we breathe, indoors and outdoors, has a direct effect on our health and comfort. You may notice some of the more prominent side effects of indoor air pollution, like an unpleasant odor, but many others go undetected.

Indoor air pollution can cause serious health issues, including:

  • Headaches
  • Fatigue
  • Sore eyes
  • Burning nose
  • Worsening allergies
  • Respiratory issues
  • Flu-like symptoms
  • Heart disease
  • Cancer
  • Other serious, long-term conditions
  • Death, when carbon monoxide or other pollutants are present in high concentrations

You‘re not just buying an inspection.

You’re buying peace of mind.
