Commercial Radon testing

Protect your workplace from hidden risks

Many assume radon is only a problem for private homes—but commercial buildings are often at equal or higher risk. Because radon is invisible, odorless, and tasteless, it can only be detected through radon testing. For commercial properties, this process is known as Commercial radon testing or workplace radon measurement — and it’s a vital part of ensuring a safe and healthy workplace. Large foundations, basements, and HVAC systems can trap radon gas indoors, allowing it to accumulate to harmful levels.

Radon is a naturally occurring radioactive gas that seeps from the ground into buildings. Although it’s invisible and odorless, long-term exposure to elevated radon levels is the second leading cause of lung cancer worldwide, according to the World Health Organization (WHO).

Radon testing and mitigation for Businesses

Every business has a responsibility to create a safe and healthy environment for employees, customers, and visitors. Radon is one of the most serious threats to indoor air quality and it often goes completely unnoticed. For business owners, property managers, and facility directors, radon is both a health and compliance issue. Regular commercial Radon testing and mitigation are essential steps toward creating safer workplaces and protecting employees and visitors alike

Why Commercial radon testing is important

Unlike most workplace risks, radon gives no warning signs. Long-term exposure to high radon levels increases the risk of lung cancer. This has been identified by health authorities as the second leading cause of lung cancer worldwide after smoking, according to the World Health Organization (WHO).  Whether you manage an office building, a warehouse, a school, or a retail space, regular testing identifies potential issues early and helps maintain compliance with local regulations. Radon testing for businesses ensures that the indoor air your team breathes every day is safe.

Who needs to do commercial Radon testing?

Any organization with employees working indoors should test for radon, especially those located at or below ground level. This includes:

  • Offices and corporate buildings
  • Schools, universities and kindergardens
  • Healthcare facilities and nursing homes
  • Hotels, gyms, and public buildings
  • Industrial plants, factories, and warehouses
  • Government or municipal buildings

Even modern or newly built facilities can have problems with high Radon levels. The construction quality, ventilation systems, and soil composition all play an important role.

How Radon enters Workplaces

Radon gas moves through the ground and seeps into buildings through small openings and structural gaps. In large commercial or industrial buildings, HVAC systems, elevator shafts, or underground garages can affect how air moves and where radon can accumulates into high levels and be a health risk.

Because every building is unique, workplace radon measurement requires a tailored approach. Professional radon testing companies strategically place detectors throughout the building to measure concentrations in areas where people spend the most time.

Even neighboring buildings can have very different radon levels — which is why testing every property individually is so important.

Commercial radon testing process – how it works

Professional commercial radon testing is simple and can be completed without disrupting daily work. The process usually includes:

  1. Site investigation – A certified specialist investigates the building layout, the foundation and occupancy patterns to determine the most suitable testing points.
  2. Placement of detectors – Small radon detectors are discreetly placed in key rooms or zones throughout the building.
  3. Testing period – The detectors collect data over a set period (typically 10 days to 3 months). It depends on what period is used, a short-term or long-term test.
  4. Analysis and reporting – After the test period, the detectors are analyzed in a certified laboratory. Then you will receive a detailed report showing radon levels across the building.
  5. Certified Reporting and Documentation
    After testing, professional radon measurement providers deliver a certified report showing all results, test locations, and recommendations. These reports can be used as official documentation for health inspections or internal safety audits, helping demonstrate compliance with workplace safety laws.
  6. Recommendations and mitigation – If radon levels are found that are above the recommended limit, you’ll receive expert advice on mitigation options in the report. For example, improved ventilation or depressurization systems

This professional approach ensures reliable results for any type of commercial or public building.

Short-term versus long-term radon testing

There are two different ways to do the testing in terms of time period and depending on the purpose of the testing.

  • Short-term tests (10–30 days. Provides a quick overview and is useful for initial review or legal government inspections
  • Long-term tests (90 days or more): Offer a more accurate average, accounting for seasonal changes and fluctuations in building use.

For workplaces there is often recommended to do long-term radon testing to ensure more precise year-round results.

What to do if levels are high?

If testing shows radon concentrations above the recommended limit, it is important to take action and find the right solution. There is no need to panic! The problem can be fixed effectively.

Today modern radon mitigation systems can reduce radon levels by up to 90%. Common solutions include:

  • Installing ventilation systems that remove radon from beneath the foundation.
  • Sealing visible cracks or gaps in floors and walls.
  • Adjusting building pressure and airflow to prevent radon infiltration.

Once improvements are made, it is important to do a follow-up workplace radon measurement to confirm that the issue has been properly resolved.

Radon mitigation for businesses

There are several commercial radon mitigation solutions to help reducing radon.
If high levels are measured, professional mitigation systems can quickly and effectively reduce radon from beneath the foundation and vents it safely outdoors.

For large commercial buildings, mitigation can be integrated with existing HVAC systems to improve airflow and pressure balance. It can be done without interrupting daily operations.

Regulations and action levels

Across Europe, the EU Directive 2013/59/Euratom requires all member states to monitor and control radon exposure in workplaces. In Norway and most European countries, the recommended action level is 100 Bq/m³, while 200 Bq/m³ is the legal limit requiring mitigation.

That means employers must carry out radon testing for businesses to identify potential risks and take action to solve the problem if needed. Failing to comply can expose your company to legal issues and health risks. Proactive testing ensures compliance with occupational safety standards and peace of mind for everyone in the building.

How often should businesses test for radon?

Initial radon testing should be performed in all occupied buildings. If levels are below the recommended limit, retesting is advised every 5–10 years. In following cases more frequently as:

  • Major renovations or structural changes has been done
  • Alterations to HVAC or ventilation systems
  • Changes in building usage (e.g. converting a basement into office space)

Regular testing ensures long-term compliance and continued indoor air safety.

Invest in a healthier and safer workplace

Radon may be invisible, but the benefits of testing are clear. By scheduling commercial radon testing, you take a proactive step toward protecting your team, your customers, and your business. Whether you manage a single office or a national network of facilities, radon testing for businesses is one of the simplest and most effective ways to ensure indoor air quality and regulatory compliance.

Don’t wait for problems to appear — test for safety today.
