Radon testing
in indoor air


We provide services to measure radon concentration in new-build and refurbishment projects, workplaces, homes, and public buildings. For this purpose, we use an analysis laboratory accredited according to the ISO/IEC 17025 standard for measuring radon in air.

Our service follows the protocols established in Instruction IS-47, and complies with the requirements of DB HS6 of the Technical Building Code (CTE), and RD 1029/2022 on occupational exposures.

Existing buildings and new construction

In its December 2019 update, the Technical Building Code requires measures to reduce exposure to radon gas in new buildings and in interventions on existing buildings.

In the case of refurbishment works and interventions in existing buildings, a prior radon test is necessary to assess whether it is appropriate to include corrective actions against radon in the project. The radon concentration obtained from this test also determines the type of measure most suitable to reduce the radon level below the reference level.

For new buildings, certification of the radon levels in the finished building gives the client assurance that the regulations concerning occupant exposure to radon are being met.

Radon tests according to the Technical Building Code

We provide a complete and flexible service covering the planning of the sampling phase, sample collection (with passive detectors), analysis of the data obtained, and preparation of the report, all tailored to the client’s needs.

The typical measurement period for this service is 60 days, in line with CTE recommendations.

The measurement service we offer uses an analysis laboratory accredited according to ISO/IEC 17025. The radon detectors we use are passive devices, do not consume energy, and contain no harmful components.

Workplaces

We provide services to measure radon gas concentration in commercial premises, workplaces, and underground areas.

We offer radon tests through an analysis laboratory accredited according to ISO/IEC 17025, which applies the procedures established by the Nuclear Safety Council (CSN) for measuring radon in air.

Our service adapts to the client’s needs and can include study planning, placement and removal of detectors, or only sending the required number of detectors (a common option in occupational risk prevention services).

The radon detectors we use are passive devices, do not require power, and contain no harmful components.

Mandatory radon tests (according to RD 1029/2022)

From 24 June 2024, radon measurements are mandatory in all workplaces located in basement or ground floors within the “priority action municipalities”. Currently, the “priority action municipalities” are defined as Zone 2 municipalities according to the Nuclear Safety Council.

In addition, it is mandatory to carry out radon measurements in underground workplaces, such as construction sites, tunnels, mines, or caves, and in places where water of underground origin is processed, handled, or used, such as thermal activities and spas.

The typical measurement period for this service is 90 days.

Non-mandatory radon tests

Radon gas is part of the air your employees breathe, and therefore poses a risk in workplaces, especially if radon levels in your premises or office are above the action levels recommended by the competent authorities for the general public.

We work directly with companies or in collaboration with Occupational Risk Prevention Services to determine whether radon levels could affect employees’ health, even when the work activity is not subject to a legal obligation.

We provide a clear and understandable analysis and interpretation of the results and, if necessary, recommend appropriate measures to reduce radon levels in your workplace.

Radon tests of this type can be carried out over measurement periods of 7 or 90 days, depending on the needs of the study and the type of facility.

Radon tests in homes

It is easy to find out the radon gas concentrations in your home: we send the radon detectors by courier, with simple instructions on where to place them, and we collect them in the same way after the measurement period.

The detectors are passive (they do not require any power supply) and do not contain any harmful components. In the standard service, 2 detectors are sent, and additional detectors can be added.

After collection and analysis, we issue a report on the radon levels found.

We offer 2 types of service: quick measurements (7 days) and standard 3-month measurements.

Standard measurement: 3 months

To obtain a more accurate value of the annual average radon concentration, for example for legal comparison with reference levels, the detectors must be left in the measurement area for a long period; we usually use a period of 90 days.

The 3-month test should be carried out under “normal” conditions, meaning that windows and doors can be used as usual.

Quick measurement: 7 days

If you need to know the radon levels in a home quickly, this is the best option. For example, before purchasing a property, when planning refurbishments, or simply to rule out concerning levels of radon.

The 7-day test must be carried out under “closed-house” conditions, meaning that windows and doors in the measurement area should normally remain closed (except for entering and leaving).
