Radon is everywhere – even where you live

Many live in the belief that radon does not exist where they live. That’s wrong. Radon gas is everywhere. The key question is, how much radon are you exposed to? In order to reduce the number of lung cancer cases in the United Kingdom, the target value for radon in indoor air should be 100 Bq/m3.

Brief facts – where you’ll find radon

  • Radon can be found in the soil throughout the United Kingdom. However, its concentration may vary.
  • Even “low-risk soil” may have sufficiently high concentrations of radon to cause problems.
  • You can´t rely on radon maps as they don´t show radon levels in specific buildings.

Reducing radon content – cheap life insurance

A common reason why homeowners do not measure radon is that they believe any rectification will be expensive and complicated. That’s not the case. If measurements indicate a radon content level above the 100 Bq/m3 target value, there are cost-effective solutions available to address the problem. Want to know more?

The 4 most frequently asked questions regarding indoor radon levels

Why is radon dangerous?

After smoking, exposure to high levels of radon is the most common reason for developing lung cancer. According to Public Health England (PHE), in the UK more than 1,100 people annually are affected by radon. Radon gas is radioactive and when it enters the lungs it emits alpha radiation from its decay which harms human pulmonary tissues which over time can lead to lung cancer.

Where does radon come from?

Radon is a decay product from the radioactive element radium226, which in turn is a decay product of Uranium238, found naturally in soil. As radon is a gas it easily leaks from the soil into houses through tiny cracks in foundations and walls.

In terms of air pressure, a house is an insulated heated environment (as opposed to breathing outside), so the probability of radon exposure is much higher indoors. Due to this, high concentrations of radon can easily build up. In rare cases radon can also be emitted from building material with high levels of radium.

How do I measure radon levels indoors?

The best way to establish radon levels in your house is to measure with a radon test kit. Due to weather conditions, temperatures and atmospheric pressure, radon levels vary day to day which is why PHE recommends that a measurement period should be at least three months. Radon is only harmful if you are exposed to it for a long period, which is why measurement is conducted over three months to obtain an accurate risk assessment. If a faster analysis is needed, we recommend a minimum ten-day measurement period. This can be carried out with a rapid radon test kit.

The Government advises that remedial action should be taken in any residential property with an average annual radon level of 200 Bq/m3 or more. Although, the target level to reach is 100 Bq/m3, which is in the line with what The World Health Organization (WHO) recommends as a limit value for radon.

Digital monitors are also an option for measurement. However, these are normally used to follow up remediation work. We do not recommend evaluating the risk of radon using radon maps as radon levels can vary substantially due to the local variations in soil and different building types. For workplace radon testing there are specific requirements, which you can read more about here.

How do I reduce high levels of radon?

There are many different technologies for reducing radon in your home to acceptable levels. As Radonova is an independent validated laboratory and accredited to ISO 17025 we cannot conduct radon mitigation work. Companies providing mitigation services can be found on or

Who are we?

Our history

Radonova laboratories, formerly Landauer Nordic and Gammadata Mättekinik, was founded in 1986 following the Chernobyl nuclear accident. After the disaster, the Swedish government commissioned a group of researchers from Uppsala University to measure the fallout from the accident, inside and outside Sweden. This is how a young company with a bright future was born.

Radonova has been measuring radon on a large scale since 1989 and has built a strong reputation for its quality and professional approach to the subject of radon gas exposure linked to health risks. Now, number one worldwide, the company measures radon in more than 80 countries. Read more here.

Radonova laboratories is a company which belongs to the Lagercrantz Group.
