Radon Gas In Your Home May Cause Lung Cancer

Radon is the number one cause of lung cancer among non-smokers, according to the U.S. Environmental Protection Agency (EPA). Overall, radon is the second leading cause of lung cancer and is responsible for more than 20,000 lung cancer deaths every year. Thousands of these deaths occur among people who have never smoked.

I’ll bet many of you didn’t know that (I didn’t – until researching this).

Where does Radon gas and radiation come from?

Radon is a naturally occurring radioactive gas. It emanates from the ground and into the air as a result of Uranium breaking down in the soil.

Radon is present worldwide, and its concentration depends on the uranium content of the soil.

Radon in our homes accounts for 50% of the public’s exposure to naturally-occurring sources of radiation, according to the World Health Organization (WHO).

The gas escapes easily from the ground into the air and emits heavily ionizing radiation called alpha particles.

These particles are electrically charged and attach to dust and other particles in the air we breathe.

As a result, the alpha particles can damage our DNA and potentially cause lung cancer over time.

How Does Radon Get Into The House?

Radon gas gets into your house through cracks at concrete floor-wall junctions, gaps in the floor, pores in hollow-block walls, and also sumps and drains.

Because of this, radon levels are usually higher in basements, cellars or other areas in contact with soil.

How do I know if Radon levels are too high?

The U.S. EPA recommends homes be repaired / fixed / mitigated if the radon level is 4 pCi/L (pico Curies per Liter) or above — although they do recommend considering action above 2 pCi/L.

There are several methods you can use to determine the level of radon gas in your home.

1. A professional who comes to your home to take measurements.

2. A do-it-yourself kit which can be purchased to absorb measurements that you then send to a lab for analysis.

3. A radon gas detector for the home.

  1. Radon is the reason that human life expectancy is limited.
    The average person will be contaminated with a lethal enough dose of Radon by 150 years old.
    The average persons life expectancy is determined by
    (a) Genetics
    (b) Lifestyle.
    With genetics being the most significant contribution.

    Wooden houses are less susceptible to Radon contamination. Houses should be kept aired and dusted.

  2. The radon gas acceptable levels are 2 to 3 times lower here than in other countries and are based on uranium miners from the late 1950’s.

    1. Correction: You should have said “will”, not “could”. The trick is to lengthen the time of “alive” by being aware of your risks and then doing something about it. ;)

  3. Performing a radon test is the first step in looking out for your family’s health. Testing can be done by a professional or “do-it-yourself” kit. Because radon levels can vary from day to day and from season to season.

  4. There is no safe level of radon but you can fix a radon problem through radon testing the only way to know if you and your family are at risk from radon.

  5. The best thing you can do is not ignore its presence and take proactive steps. A home inspection is the only method that assures you of your safety.
