Analyses and evaluations

HSE Conseils SA offers several kinds of radon analyses such as air, soils, materials and water analyses. Our specialists can advise you on the most adapted method depending on the purpose of the analysis. HSE Conseils SA is accredited by the Federal Office of Public Health (FOPH) as radon measuring laboratory.

Direct reading analyses and monitoring

HSE Conseils SA offers radon analyses measured with a direct reading instrument (Alphaguard PQ2000Pro). This instrument allows to determine real-time radon concentrations and to monitor radon concentrations. This type of measurement is especially adapted to determine the entering point of radon gas in a building or, for example, to perform tests before decontamination (evolution of radon concentrations while installing a ventilation system). This type of measurement also allows the control the efficiency of decontamination processes.

Trace dosimeters

Our office and lab are accredited by the FOPH for this type of measurements. Notice that until winter 2009/10, the FOPH organizes every winter important measuring campaigns. Dosimeters are distributed for free in numerous Swiss municipalities. Therefore, we recommend you to ask your local authority first

Short-time analyses

To obtain results relatively rapidly and at moderated costs, we offer the possibility to proceed to analyses with “Ramon 2.2” instruments. These instruments give a first result after 48 hours and the average is then adjusted every hour. This type of analysis is especially interesting before the acquisition of a building.

Radon analyses in soils and materials

By using several instruments, we are able to perform radon analyses in soils and building materials.

Radon analyses in soils are especially useful before building constructions in areas of radon risks. If needed, adapted methods against radon dispersion can be applied to the building.

Radon measurements in materials allow to determine the source of radon in a building (soil, walls, etc) and to take adapted decontamination measures.

Water analyses

Radon analyses in water are useful for several purposes. One of the purposes is to determine the input of radon to the air in a building by water degassing. Another application of the analyses in water is to quantify radon concentration in drinking water and to determine the risks for health.
