What Is Radon Gas?
Radon is a colourless, odourless radioactive gas. It is formed by the radioactive decay of the small amounts of uranium that occur naturally in all rocks and soils.
How Dangerous Is Radon Gas?
Radon is a dangerous radioactive gas which can’t be detected by humans, as it is invisible and has no smell or taste. It accounts for half of the radiation we are all exposed to daily, with the other half coming from a mix of sources. At normal levels, this radiation is harmless, but exposure to a radiation source like radon above safe levels is dangerous and can cause serious health problems.
Radon Gas & Lung Cancer
Radon is the number one cause of lung cancer among non-smokers, according to EPA estimates. Overall, radon is the second leading cause of lung cancer. Radon is responsible for about 21,000 lung cancer deaths every year. About 2,900 of these deaths occur among people who have never smoked. The early signs and symtoms of lung cancer to be aware of;
- Persistent cough.
- Coughing up blood.
- Shortness of breath.
- Chest pain, especially when you cough or laugh.
- Frequent infections such as bronchitis and pneumonia

Frequently Asked Questions
Radon is a radioactive gas, we can’t see, smell or taste it: you need special equipment to detect it. It comes from the rocks and soil found in the Cotswolds and Gloucestershire areas. The radon level in the air we breathe outside is very low but can be higher inside buildings.
The only way to know if a building / home has a high radon level is to have it tested. If you live or work in a radon affected area we recommend that a test is arranged. You can arrange a test at www.ukradon.org
High levels of radon can cause lung cancer, particularly for smokers and ex-smokers. Radon produces tiny radioactive particles in the air we breathe. Radiation from these particles damages our lung tissue, and over a long period may cause lung cancer. The higher the level and the longer the period of exposure, the greater the risk will be.
The Target Level of 100 Bq m-3 is the ideal outcome for remediation works in existing buildings and protective measures in new buildings. If the result of a radon assessment is between the Target and Action Levels, action to reduce the level should be seriously considered.
Positive ventilation brings fresh air into a home, and dilutes the radon. The flow of air and radon from the ground may also be reduced. A positive ventilation system can be effective in homes with radon levels up to and around 500 Bq m-3
A typical system has a fan in the roof-space connected to a vent in the ceiling. There are units for properties, such as flats, without a roof space. A filter ensures that the air is clean:
- Dampair PIV units come with a integral built in heater
- The fans are quiet
- The unit costs approx £30 per annum to operate
Installation is quick and simple; the units are normally supplied and fitting by Dampair. A vent is fitted centrally in the ceiling, normally in a hallway or stairwell. The systems improve air quality and also reduce condensation and mould issues.
It takes a Dampair technition on average 4-5 hours. They will leave your property clean and tidy.
Yes. We need someone to be at the property to let us in. All our installers are DBS checked therefore if you do need to leave the property you can feel safe and comfortable.
Nothing, the PIV unit is fully automatic. Just leave it to reduce the Radon Gas levels in your home.
