Measurement of radon with radon detectors from the world’s leading laboratory

Radon is a radioactive gas which forms when the naturally occurring element Uranium238 found in rocks, soils and man-made building materials, spontaneously decays. Radon is a natural radioactive gas, but you can’t see, smell or taste it, which makes it a challenge to detect and measure. In outside air the levels are low but it can accumulate inside buildings. Certain areas of the country are more prone than others.

According to the World Health Organization, (WHO), between 3% and 14% of all incidences of lung cancer are caused by radon. The risk varies depending on where you live in the UK and the local geology. Public Health England estimates that about 1,100 cases of lung cancer per year are caused by breathing in radon present in British homes and your place of work or study. If you live, work or maybe study in a property with a high radon level, i.e. a radon level that exceeds the target level of 100 Bq/m³, you run a greater risk of being affected. You should therefore measure radon in your home and your employer should consider measuring radon levels where you work.

Radonova operates the world’s leading laboratory for the measurement of radon in houses, multi-occupancy buildings and workplaces. Our highly accurate and secure measurement methods are accredited according to ISO 17025. Using our radon detectors enables you to obtain a reliable assessment of the radon level in your home or workplace.

Our service provides you with the correct radon detectors specifically designed for your particular situation. All you need do is place the radon detectors in the building to be checked as per the simple instructions that come with the detectors. You then log on to our website, set up a password protected account, and indicate when the measurement period started, and ultimately finished, before sending the detectors back to our laboratory free of charge.

On receiving the detectors from you we analyse them for traces of radon gas which have been recorded in the detector. From the results we can make an accurate and reliable assessment of the yearly average radon level for a property and if it is above or below the UK recommended Action Level. Should an assessment above 100 Bq/m³ be indicated then remedial steps can be taken to reduce the Radon level in the building,

Radonova work closely with research institutions and leading academics in the UK involved with radon detection, measurement and subsequent remedial work to reduce dangerous levels of radon build up in buildings. We are members of the UK Radon Council and European Radon Association, keeping up to date with all advances and developments in radon detection and measurement.

Our company laboratory employs highly competent technical staff using state of the art equipment to analyse our radon detectors: Radtrak²®, Rapidos® and Duotrak®.

In addition to our own internal quality control and monitoring procedures we participate in comparative international tests, independently run by Public Health England (PHE), to ensure you can always rely upon the results we provide.
