Radon - The invisible danger in buildings

What is radon?

Radon is a naturally occurring, radioactive noble gas that escapes from the ground.
It is invisible, odorless and tasteless – and can only be detected by measuring radon.
The issue is particularly important in public buildings, where many people spend time every day.

How does radon get into buildings?

Radon rises from the ground and enters the building through cracks in the foundation, leaking joints or pipe penetrations.
Basements, sports halls, administrative rooms on the first floor or poorly ventilated adjoining rooms are particularly affected.

Without targeted measures, the gas can accumulate in the indoor air and cause health risks.

Why is radon dangerous in buildings?

Radon exposure affects not only individuals, but entire groups:

  • Children in schools and kindergartens
  • Employees in public authorities, administrations or companies
  • Visitors to public institutions

In the long term, an increased radon concentration can significantly increase the risk of lung cancer. Legislation therefore stipulates mandatory measurements for certain regions.

 

What is a radon sensor?

A radon sensor measures the concentration of the radioactive noble gas radon (Rn-222) in indoor air. Radon occurs naturally in the ground and can enter buildings through cracks, joints or pipe penetrations. Radon can accumulate indoors and poses a relevant health risk, particularly in workplaces.

Professional radon sensors enable continuous measurement in which changes in the radon concentration are detected promptly. This is a significant advantage over traditional long-term measurements, which only provide an average value retrospectively.

Legal requirements in Germany

According to the Radiation Protection Act, a reference value limit of 300 Becquerel per cubic meter (Bq/m³) has applied to recreation rooms and workplaces since 2021.

Public facilities in designated radon precautionary areas are obliged to carry out radon measurements.

If the reference value is exceeded, protective measures must be implemented to permanently improve the indoor air.

Measures against radon in public buildings

To ensure the safety of pupils, staff and visitors, the following steps are recommended:

Radon measurement: Check with measuring devices over longer periods of time.
Regular ventilation: Especially in classrooms and common rooms.
Building renovation: Seal cracks and leaks in the foundation.
Technical solutions: Use of ventilation or radon extraction systems in more severely affected buildings.
Monitoring: Continuous monitoring of indoor air quality.

Why use a professional radon sensor for occupational safety?

Radon is one of the most common causes of lung cancer after smoking. In many countries – including Germany – radon is therefore a relevant topic in occupational health and safety, particularly in:

  • rooms in contact with the ground
  • Basement floors
  • Existing buildings
  • Regions with increased radon potential

A professional radon sensor for companies helps with this:

  • Recognize radon exposure at an early stage
  • Minimize risks for employees
  • document measurements in a comprehensible manner
  • make informed decisions about ventilation or refurbishment measures

EnoSense® RADON is expressly not a consumer product, but has been developed for systematic use in organizations and institutions.

EnoSense® RADON - Features and benefits of a professional radon sensor

The EnoSense® RADON impresses with its clear focus on professional requirements:

  • Continuous radon measurement instead of just long-term averages
  • Suitable for continuous operation indoors
  • Designed for companies, authorities and public institutions
  • Supports occupational safety and building management processes
  • Low-maintenance operation
  • Clear differentiation from residential and end customer products

The continuous recording allows temporal patterns to be recognized, e.g. dependencies on ventilation, usage or time of day.

EnoSense® RADON - Radon measurement with a system

With EnoSense® RADON, you are choosing a radon sensor that has been specially developed for companies, institutions and professional users. For reliable, continuous radon measurement in the context of occupational safety and building operation.

Note: The EnoSense® RADON is aimed exclusively at the B2B sector and is not intended for private residential use.

Conclusion - Responsibility for health and safety

The operator has a special responsibility in public buildings.
Radon is an invisible danger, but it can be controlled with simple measurements and suitable radon protection measures.
Those who act in good time not only protect the health of users, but also comply with legal requirements.

 

Ecosense - partner for precise radon sensors

Our EnoSense radon sensor uses state-of-the-art measurement technology from the US company Ecosense Inc., a global leader in radon measurement.

Ecosense develops highly sensitive radon sensors based on semiconductor detectors, which enable a particularly fast response time and high measurement accuracy. This allows radon concentrations to be monitored continuously and reliably – both in living and working spaces and in specialized applications.

By integrating this technology into our EnoSense radon sensor with EnOcean wireless interface, we combine precision in measurement with flexibility in building automation.

👉 Result: Our customers benefit from reliable monitoring in accordance with the requirements of the Radiation Protection Act and at the same time receive a future-proof solution for the smart building.

Areas of application for the Radon sensor in the B2B environment

The EnoSense® RADON is suitable for a wide range of professional application scenarios:

  • Companies and industry (workplaces, production areas)
  • Public buildings and administrations
  • Authorities and municipal facilities
  • Real estate operators and facility management
  • Educational institutions such as schools and universities
  • Health and care facilities

It is particularly useful in permanently used indoor spaces with floor contact or limited ventilation.

Radon sensor vs. long-term measurement - which approach makes sense?

The question often arises as to whether a classic long-term measurement or a continuous radon sensor is the better choice.

Long-term measurement:

  • provides a retrospective mean value
  • No prompt reaction possible
  • No statement on daily or usage-dependent fluctuations

Radon sensor (continuous):

  • shows changes in radon concentration in real time
  • Enables targeted measures (e.g. ventilation)
  • Ideal for ongoing operation and monitoring of workstations

For companies and operators, a professional radon sensor therefore offers significant added value compared to purely one-off or long-term measurements.

Frequently asked questions about radon sensors (FAQ)
