Question: What Happens If Radon Levels Are High?

What are the chances of getting cancer from radon?

Some estimates suggest that approximately 14% of the 300,000 annual lung cancer cases in the United States are attributable to radon (EPA 2009b).

The World Health Organization (WHO) estimates that radon causes between 6% and 15% of lung cancers worldwide (WHO 2005)..

How long do you have to be exposed to radon before it becomes a problem?

Radon gas can damage cells in your lungs, which can lead to cancer. Radon is responsible for about 21,000 lung cancer deaths each year in the United States, though it usually takes 5 to 25 years to develop.

At what level does radon become dangerous?

The best radon level measurement would be zero. Unfortunately, that’s not possible. The average global outdoor radon level varies between 5-15 Bq/m3, equal to 0.135-0.405 pCi/L. For every 99.9 Bq/m3, or every 2.7 pCI/L increase in long term radon exposure, lung cancer risk rises 16%4.

Where is Radon most common?

Radon is present everywhere in the United States. Levels of the gas differ from state to state, but it is particularly high in North Dakota and Iowa. The U.S. Environmental Protection Agency’s Map of Radon Zones shows the potential for elevated radon levels for each county in the United States.

Is radon worse in summer or winter?

To answer that question, yes, radon levels in a home tend to be higher during the winter. And those higher levels of radon gas can lead to an increased chance of lung cancer. While indoor radon gas levels are generally higher during winter, sometimes the summer can have higher indoor radon levels.

Does finishing basement reduce radon levels?

Radon mitigation in finished basements: Most newer homes would have a vapour barrier below the slab, though likely not well-sealed. Some homes will have none, but in either case, concrete in fairly good condition should provide enough of an air barrier to contain radon below it.

Is radon really that dangerous?

When radon gas enters the body, it exposes the lungs to small amounts of radiation. In small quantities, experts say this is harmless. However, in persistent exposures or larger quantities, radon can damage the cells of the lining of the lungs, increasing a person’s chance of developing lung cancer.

How do you get rid of radon?

There’s no single method that fits all radon removal system needs. Common techniques include: Sub-slab depressurization, where suction pipes are inserted through the floor or concrete slab into the concrete slab below the home. A radon vent fan then draws out the radon gas and releases it into the air outside.

Should I worry about radon gas?

Radon is considered to be the largest source of exposure to natural ionising radiation. Exposing sensitive bronchial cells to radon is known to cause damage in proportion to the number of cells exposed. Radon concentration is highest indoors, particularly in houses and small buildings.

Do air purifiers reduce radon?

Air Purifiers are great for mold, dust, allergies, bacteria and viruses, and odors, but many people do not know that they can also help with toxins, gases and chemicals such as radon. The most important type of air filter to reduce radon levels is an activated carbon filter.

How do I reduce radon in my basement?

Find your type of foundation design above and read about which radon reduction systems may be best for your home. In homes that have a basement or a slab-on-grade foundation, radon is usually reduced by one of four types of soil suction: subslab suction, drain-tile suction, sump-hole suction, or block-wall suction.

Can radon cause mental illness?

Mental health experts generally agree that people dealing with the presence of high levels of radon in their homes are likely to have related psychological problems if they are prone to other forms of stress.

What do you do if your radon level is high?

If a radon test reveals high levels—anything above 4 pCi/L—ask for a walk-through with an EPA-licensed radon remediation specialist. You can find one through your state radon office. Most will provide a free remediation estimate, and, if the work is done, guarantee that radon levels will be acceptable.

Does opening windows reduce radon?

As a temporary solution, however, you can reduce radon levels simply by opening windows. Opening windows improves air circulation and ventilation, helping move radon out of the house and mixing radon-free outside air with indoor air. Make sure all your basement windows are open.

Do most basements have radon?

Radon levels are generally highest in basements and crawl spaces because these areas are nearest to the source and are usually poorly ventilated.

How do you lower radon levels in your home?

In some cases, radon levels can be lowered by ventilating the crawlspace passively (without the use of a fan) or actively (with the use of a fan). Crawlspace ventilation may lower indoor radon levels both by reducing the home’s suction on the soil and by diluting the radon beneath the house.

Will an air exchanger reduce radon?

While an air exchanger typically isn’t installed as a radon mitigation system, a running air exchanger will reduce radon levels in the home*, because stale indoor air is replaced with fresh outdoor air. * This assumes the unit has been properly installed and properly maintained.

Do most homes have radon?

Answer: All types of houses can have radon problems-old homes, new homes, drafty homes, insulated homes, homes with basements and homes without basements. Construction materials and the way the home has been built may also affect radon levels, but this is rare.

Can radon get into clothes?

Accordingly, the radon in air measurements you have made in your house, assuming the levels in the basement are not many times higher, suggests that the amount of particulate progeny that are available to attach to clothing is also quite small.

What are the symptoms of radon in your home?

Possible symptoms include shortness of breath (difficulty breathing), a new or worsening cough, pain or tightness in the chest, hoarseness, or trouble swallowing. If you smoke and you know you’ve been exposed to high levels of radon, it’s very important to quit smoking.
