What is radon?

Radon is a colorless, tasteless and odorless gas that causes lung cancer.

 It’s produced from the breakdown of uranium in soil and rocks.

Radon can reside at dangerous levels inside homes , schools and other buildings

Is radon in your home?

Radon is found naturally in the environment , so all buildings have some level of radon.

The concentration of radon in buildings depends on:

1- the uranium content

2- Cigarette smoke and furniture such

3- the routes available for the passage of radon from the soil into the building;

4- the radon exhalation from building materials;

5- the ventilation of the occupants in the building.

Why is Radon Harmful?

Radon is the second leading cause of lung cancer after cigarette smoking.

 Over time, exposure to elevated levels of radon increases a person’s risk of developing lung cancer.

According to the Environmental Protection Agency, radon contamination causes nearly 20,000 deaths a year.


How can I test my home for radon?

Radon test kits can be purchased from a variety of local stores, including hardware stores or large discount stores.

How does radon get into your home?

  •     Construction joints
  •     Cracks in walls and floors
  •     Gaps around pipes
  •     Cavities inside walls
  •     The water supply

Various measures help to restrict the concentration of radon in a building , and you could protect yourself from an increased risk of lung cancer.

1- Stop smoking  in your building.

2- it is advisable to seal the affected areas

3- installing a radon sump system in the basement or under a solid floor;

4- During radon remediation, a fan and vent pipe are typically installed in the basement to pull radon from beneath the building and vent it towards the outdoors.

5- Increase air flow in your house by opening windows and using fans and vents to circulate air.

6- Run a three to four-inch gas-tight pipe from the first layer or crawlspace to the roof. This will safely vent gases from the soil to the outside.

7- hire an experienced professional who can install a radon mitigation system. Mitigation systems effectively pull radon out of your building.

 8- Elevated radon levels in most homes and offices can be reduced to below 2 pCi/L by a radon mitigation system. The cost of a radon mitigation system runs around $1,200 to $1,500.

9- Passive systems of mitigation can reduce indoor radon levels by more than 50%.

10- Seal and caulk all cracks in your foundation and walls. Not only will this help prevent entry of radon, but it’ll add to the energy efficiency of your home.

11- The suctioning of soil air containing radon from beneath or beside buildings can also help, as can the installation of technical ventilation systems.


Always test amount of radon  again after the work is finished and then every two years.


 Radon testing  could save your life. Thousands of lung cancer deaths could be avoided each year if home and building owners acted to test and fix.


Colder conditions in winter can increase indoor radon levels, though levels tend to fluctuate throughout the year.
