The know-how and an analysis laboratory for the monitoring of radioactive and environmental contaminations

20 years of experience in the measurement of radioactivity

Radiological water analysis  – Sanitary control of water – Metal analysis

 

 

 

Pictogramme mesure radioactivité naturelle

 

PearL, 20 years of experience and know-how in the radioactivity expertise & measurements, and especially natural radioactivity

 

Strong skills

 

resulting from the outsourcing of activities carried out by the university and the CNRS within the Center for the Study and Measurement of Nuclear Radiation and Dosimetry.

 

A significant know-how

 

enabling PearL to carry both field interventions, analysis, their exploitation and interpretation for the control and monitoring of the sites.

Mesure de radioactivité independante

 

Independence, the guarantee for reliability and impartiality…

PearL operates with complete freedom for the State, local communities, 
environmental protection groups, manufacturers, private individuals

 

 

For monitoring and analysis

 

Risks of exposure

chronic or accidental, of workers or the population.

 

Environments to protect

such as catchments, lakes, rivers, ponds…

 

Contaminated sites

under mining and/or industrial influences.

Measurements conducted in our lab

In addition to the preliminary samples before testing (water, solids and bioindicators), PearL also carries out the following measurements, generally under Cofrac accreditation or under the approval of the Ministry of Health or the Nuclear Safety Authority.

Waters

Global Alpha/Beta activity, tritium, uranium, radium, polonium, natural gamma emitters, radon, Total Indicative Dose (TID)…

Solids / Bio-indicators

Natural gamma emitters from the soil, sediments, plants…

Site control

Impact of mining operations, rehabilitation of former operations…

Gamma Dosimetry

On the field or with TLD

Radon screening

In buildings, places open to the public and workplaces (N1A, N1B)

Cartography

From ground radon exhalations…

We work on issues related to natural or environmental radioactivity,
on all types of matrixes: soils, mud, sand, sediments, plants, fruits and vegetables, water (groundwater, effluents, …), fauna (fish, …)

 

The equipment and the analysis techniques were chosen according to this orientation
and extremely low detection limits are made possible.

 

The list of measures PearL practices is not exhaustive and is regularly evolving.
We invite you to get in touch for more information.
