Naturally occurring radioactive gas

Radon - Naturally occurring radioactive gas

What is it?

Radon is a naturally occurring radioactive gas, which can enter your home from the ground, exposing you to doses of radiation. In recent years, there has been considerable publicity concerning great exposure to the natural occuring radioactive gas Radon. Health studies from around the world have linked exposure to Radon to the increased risk of lung cancer, infact Radon is the second major case of lung cancer after smoking.

Could your area be more at risk?

According to a study by the National Radiation Laboratory, about 50% of the radiation dose received by the average New Zealander is from Radon. Radon is emitted by naturally occurring traces of radium in all soils. It is present everywhere. Its concentration is very low over oceans, and is variable over land masses. Its outdoor concentration can be affected by weather conditions and soil moisture content.

The United States Environmental protection agencies recommend a level of 4 becquerels per liter of air equivalent to 148 becquerels / m3

The EnviroVent Positive Input Ventilation Systems have proved to be effective in significantly reducing Radon levels, creating a healthy atmosphere in which to live, free from the harmful effects of Radon gas. They are continuous running ventilation units, which imperceptibly supply filtered air throughout your home. This process changes the airflow direction within the property to gently force the contaminated air out of the home.

How does it affect you?

Radon is produced by the natural breakdown of uranium found in rocks, sediments and water. It then permeates up through the ground and in open air dilutes to harmless levels in the atmosphere. However, when it enters our homes and work places it decays into minute solid particles known as Radon's Daughters. These particles then become trapped and can accumulate to dangerously high levels. When they are breathed in they can be deposited on the surface of the lungs, where they decay further, emitting harmful radiation directly into the lungs.
