Accurate and Reliable Radon Test Kits From Radonova

Radonova is the global leader in radon measurement. As an ISO 17025 accredited and UK validated laboratory, we have performed over 5 million measurements in over 50 countries. Our radon measurement services, which incorporates Radtrak2® and Rapidos® technologies, is a preferred methodology worldwide for homeowners, governments and private sector organizations.

The two most common ways to test a home for radon levels are via a short- or long-term test. Radonova offers a test kit for either length. Customers can order a test online and access analysis reports via our web portal, testing your home for radon has NEVER been easier.

The 3 most frequently asked questions regarding testing your house for radon

What is the most reliable and accurate radon test in the UK?

The most reliable and accurate test for radon is to use a radon test kit from a validated and ISO 17095 accredited laboratory. As an accredited laboratory, Radonova is reviewed by external auditors and has an internal system to continuously review and maintain quality control. Due to our accreditation, we must remain independent. For example, we do not conduct radon remediation work as this would conflict with our neutral role of providing assessments and analysis.

The most accurate results from a radon test are obtained from a radon test kit designed for 3 months measurement. Indoor radon levels fluctuate due to weather conditions, temperatures, and atmospheric pressure, which is why a three-month test is the most appropriate for measuring long-term risk levels. The results provide a level of accuracy which can be compared to the target level in UK of 100 Bq/m3.

If there is not time for a three-month measurement, we recommend using a ten-day measurement kit as minimum, which gives a good indication of radon levels.

For consumers, Digital radon monitors are not as accurate as detectors but can be useful when following up radon remediation work.

Where to place radon detectors?

A minimum of two detectors should be used in a house and be placed in the master bedroom and the living room, but generally it is recommended that homeowners also test additional rooms where you or your children spend a lot of time, bedrooms for example. Radonova test kits can consist of 2 – 6 detectors so it easy to order a test kit designed specifically for your home. The radon test kits also come with instructions on how to position the detectors.

What happens if I have high levels of radon?

The risk of lung cancer increases with higher concentrations of radon. Therefore, the general advice is to keep radon levels as low as possible. Public Health England recommends that radon levels in homes should be below 200 Bq/m3 which is also is endorsed by the Government. Although it also states that the ideal outcome of radon remediation work should be to reach a target level of 100 Bq/m3, which is the value the WHO recommends. Therefore, we suggest you review the possibility of reducing radon levels if your home is measured with a value above 100 Bq/m3.

There are many different methods and technologies which enable you to reduce radon in your home. For example, you could use a radon sump pump or positive pressure system. Companies which provide radon remediation work can be found on or

Long-Term Test Kit – Radtrak2®

Radtrak2® is Radonova’s long term (90+ days) radon gas detector. An extremely accurate device that is ideal for primary or mitigation follow-up testing. Radon gas levels in your home will fluctuate from day to day and the Radtrak2® will take into account all of those fluctuations and provide an average radon level for the time the detector is deployed.

This average should be compared to the UK guideline of 200 Bq/m3 to determine if action is needed to be taken to lower radon levels in the home.

Short-Term Test Kit – Rapidos®

The Rapidos® detector uses a smaller monitoring period (10+ days) to provide quick insight into levels of radon in your home. It is ideal for the property market when you need a fast response. The larger chamber allows for greater detection speed and accurate measurements, making it also the perfect detector to assess if further testing should be completed or if mitigation efforts should begin. Since the Rapidos® uses alpha track technology it is not susceptible to traditional short-term detector vulnerabilities and humidity, and therefore will not result in wasted time, money, and tests.

Traditional short-term tests have very stringent requirements on deployment time and return time. Therefore, many tests are reported inaccurately if at all, requiring multiple tests to be purchased and performed before obtaining a reliable result. With Rapidos® you avoid that.
