Facts About Radon

Indoor Air Quality (IAQ)

Don’t let poor IAQ make you sick.   We also perform the following inspections: radon, mold, allergens.

Facts About Radon

Radon is a naturally occurring gas that comes from various rocks, soils, and underground water sources.  Radon forms from the breakdown of the natural elements uranium and radium. One way radon can get into buildings is by cracks in the basement, and if the ventilation is inadequate, radon concentration can be harmful.   Radon can be anywhere, but it matters how much of it is present in relation to other air. If the concentration is high enough, then it can cause harm. In the outside air it is not harmful because radon is present in dilute enough amounts.

Radon is a silent killer.  Since there are no immediate symptoms, people can’t tell if they’re being exposed. And its effects are more hazardous for children than adults.  Because their lungs are smaller and their respiratory rates are twice as high, children are more sensitive to radon. Doctors say that, by the age of 10, a child receives twice the lung dose of an adult who’s been exposed to radon for the same length of time.

Did you know?
  • Radon is the second leading cause of lung cancer
  • Nearly one in 15 homes in the U.S. has a high level of indoor radon
  • The U.S. Surgeon General and EPA recommend all homes be tested for radon.
  • Homes with high radon levels can be fixed.

Ten Things You Should Know About Mold

1.      Potential health effects and symptoms associated with mold exposures include allergic reactions, asthma, and other respiratory complaints.  

2.      There is no practical way to eliminate all molds and mold spores in the indoor environment.  The way to control indoor mold growth is to control moisture.

3.      If mold is a problem, you must clean up the mold and eliminate sources of moisture.

4.      Fix the source of the leak or water problem to prevent mold growth.

5.      Reduce indoor humidity to 30-60%.  To decrease mold growth, vent bathrooms, dryers, and other moisture-generating sources to the outside; use air conditioners and de-humidifiers; increase ventilation; and use exhaust fans whenever cooking, dishwashing, and cleaning.

6.      Clean and dry any damp or wet building materials and furnishings within 24-48 hours to prevent mold growth.

7.      Clean mold off hard surfaces with water and detergent, and dry completely. Absorbent materials such as ceiling tiles that are moldy may need to be replaced.

8.      Prevent condensation.  Reduce the potential for condensation on cold surfaces (i.e., windows, piping, exterior walls, roof, or floors) by adding insulation.

9.      Do not install carpeting in areas where there is a perpetual moisture problem.

10.  Molds can be found almost anywhere, and they can grow on virtually any substance providing moisture is present.
