Four frequently-asked questions about radon

Why is radon dangerous?

After smoking, exposure to high levels of radon is the most common cause of lung cancer. According to UK Health Security Agency (UKHSA) around 1,100 UK lung cancer deaths are attributed to radon gas exposure each year. Radon is radioactive – when inhaled, it emits alpha radiation, harming tissues which can lead to lung cancer over time.

Where does radon come from?

Radon is a decay product of Uranium238, found naturally in soil. As radon is a gas, it seeps easily into buildings through tiny cracks in their walls and foundations.

Homes, schools and workplaces are heated, insulated indoor environments, in which high concentrations of radon can easily build up. In rare cases, radon can also be emitted from building materials containing high levels of radium, such as granite.

How do I measure radon levels indoors?

The most effective way to establish radon levels inside buildings is to measure with a validated test kit. Due to weather conditions, temperatures, and atmospheric pressure, radon levels fluctuate, which is why UKHSA recommends a measurement period of at least three months to obtain an accurate measurement.

Digital monitors are also an option, however these are normally used for conducting follow-up measurements post-remedial work.

We strongly advise against use of radon maps as a definitive means of testing. Maps only highlight local risk due to variations in the soil, and therefore cannot indicate levels within buildings.

How do I reduce high levels of radon?

The Government advises that remedial action should be carried out in any residential property with an average annual radon level of 200 Bq/m3 or more. The World Health Organization (WHO) recommends a target level of 100 Bq/m3 for indoor radon.

School and workplace radon testing has more specific requirements, which you can read more about here.

Simple methods exist to reduce indoor radon levels. Reputable organisations providing mitigation services can be found at UK Radon Association or The Radon Council.

Our history

Following the Chernobyl nuclear disaster in 1986, the Swedish government commissioned a group of researchers from Uppsala University to measure the fallout from the accident, inside and outside Sweden. Radonova Laboratories, formerly Landauer Nordic and Gammadata Mättekinik, was founded.

Radonova has been measuring radon on a large scale since 1989 and has built a strong reputation for its quality measures and professional approach. Now a global leader, the company measures radon in more than 80 countries. Read more here.

Radonova Laboratories is part of the Lagercrantz Group.
