Why is radon important?

Radon is the number one cause of lung cancer amongst non-smokers¹.

Approximately 21,000 people die from radon-related lung cancer every year in the United States alone².

Due to radon’s fluctuating nature, long term, daily monitoring is necessary. If you discover your home has high levels, contact your local EPA or WHO for more information.

Airthings Wave is a smart radon detector which let you monitor your fluctuating radon levels over time.

Long term measurement matters

Radon levels fluctuate over time and are influenced by the elements in our environment. Monitoring over longer periods of time allows for such fluctuations to be accounted for, giving you more accurate and meaningful results.

Where does radon come from?

The rocks and soil beneath our homes contain traces of uranium. Over time, the uranium breaks down and forms other elements. This is called radioactive decay. Radon is one link in the decay chain of uranium. When radon gas decays, it emits radioactive radiation in the form of an alpha particle.


Radiation & DNA

When an alpha particle hits our DNA it can cause damage to a cell´s blueprint. Cells constantly replicate themselves, but with a broken blueprint the replication process can become cancerous.

Wave-particle duality
According to particle physics, any form of radiation can behave as both a particle and as a wave depending on how you observe it. That is why an alpha particle is the same as alpha radiation.

All our cells contain DNA, which acts as an instruction manual or blueprint for cells on how to create copies of themselves.


Radioactive radiation

Radioactive radiation takes the form of alpha, beta, gamma, x-ray, and neutron radiation, which are able to penetrate different substances.

External skin: Alpha particles do not penetrate external skin because it consists of dead skin cells.

Internal tissue: Ingesting or inhaling alpha- particles is a health concern because living cells are not able to stop the radiation.


Radon geography

Local variations
The local variations in radon levels are often significant. Two homes right next to each other can have completely different radon levels. That is why no region is exempt from radon measurements.

Industrialized world
Well-built homes in industrialized nations are often more prone to excess radon levels due to their insulation.

On a boat?
Radon levels at sea are usually quite low.


Radon usually builds up in the lowest levels of a building. However, there are some buildings that have a higher radon level in the top floors. This can be due to artificial ventilation, natural updraft, or building materials used.

Measuring all floors can help us make healthier decisions. In most cases, it is better for our health to spend more of our time on floors with lower radon levels.

Take control of your radon levels.

How to measure radon

  1. Get a radon detector.

  2. Mount the device to the wall or ceiling, or place it on any surface.

  3. Install the Airthings App for Android and iOS
  1. Read your numbers in the app, or on the Airthings Dashboard. The first indication of your radon level will appear in one hour.

  2. Monitor over time. The longer you measure, the more accurate your readings.
