Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in rocks and soil across the UK.
While harmless outdoors, it can build up indoors, especially in poorly ventilated properties or developments located in radon-affected areas.
Long-term exposure to high radon levels is a leading cause of lung cancer, contributing to over 10% of cases in the UK. For developers, landlords, and employers, radon monitoring isn’t just good practice, it’s a legal requirement under HSE and Building Regulations.
Accurate radon testing allows you to:
- Determine if radon mitigation is required before or during development
- Protect occupants and site users from harmful gas exposure
- Ensure compliance with IRR17 and Health & Safety at Work Regulations
If you’re developing land and property, it is important to understand the radon risks for future developments. Our radon survey services can help determine if radon mitigation strategies are required.
Our Radon Survey & Testing Services
Earth Environmental & Geotechnical offer a comprehensive range radon testing, gas monitoring, and soil assessment solutions, supporting residential, commercial, and infrastructure projects throughout the UK.
1) In-Situ Radon Soil Gas Testing (MARKUS 10)
Our team uses the MARKUS 10 instrument to measure radon gas directly within soils, providing accurate on-site readings within minutes. This service helps determine whether additional radon mitigation or monitoring is needed, particularly in sites highlighted in the UK Radon Atlas as medium or high-risk.
These in-situ radon gas surveys are often required to support town planning permission applications, ensuring the development, or plot, is suitable for use without any further remediation work. Our radon testing also uses CLEA and RCLEA models to assess potential radon exposure risk.
2. Ecotrak® Radon Soil Monitoring
Exclusive to Earth Environmental, Ecotrak® is a cost-effective and accurate early detection system ideal for pre-development and planning applications. It allows developers to make informed decisions on whether new residential or commercial properties require radon mitigation measures. Ecotrak® detectors are:
- Certified for international comparative testing
- Is supplied in protective Tyvek bags for soil durability.
- Has flexible storage and batch analysis options.
- Ideal for developers requiring fast, dependable radon risk data.
By identifying radon-prone sites early, you can proactively design radon-proof developments or implement mitigation measures from the outset, saving time, finances, and compliance issues later down the line.
3) Radon Monitoring for Existing Commercial & Residential Properties
In partnership with laboratories, we provide radon monitoring and testing in existing homes and commercial buildings. This is essential for landlords, employers, and property managers who must ensure indoor radon levels remain below the UK radon action level of 200 Bq/m³.
If levels exceed recommended limits, our radon specialists can advise on appropriate radon mitigation strategies to reduce exposure and meet safety standards.
4) Radon Gas Risk Assessment Services
National radon mapping covers 1km² grid areas, providing only generalised risk. Our site-specific radon risk assessments use data from MARKUS 10 and Ecotrak® instruments to deliver accurate, actionable radon hazard reports for:
- Planning submissions
- Phase 1 and 2 investigations
- Ground gas and contaminated land assessments
Our radon risk assessment services provide detailed, site-specific insights that go beyond coarse national mapping.
That’s why site-specific radon surveys and radon risk assessments are an essential step for planning applications and new developments.
Whether you’re evaluating a brownfield site, planning a new build, or assessing risks for existing properties, our radon survey consultants deliver expert advice and clear, actionable reporting.
