The Low-level Radioactivity Measurements (LRM) expert group identifies and quantifies low levels of radioactivity in a variety of samples. The origin of the radioactivity in those materials can be natural or man-made.
We are specialised in monitoring and quantifying radioactivity in:
- Food and feeding stuff (e.g. in the frame work of export)
- Drinking water
- Environmental samples (surface waters, rain water, air dust, soils, sediments, vegetation)
- Bio-assay samples (nose-blow, urine, faeces) for routine follow up of professionally exposed workers or for special monitoring
- NORM samples (e.g. waste stream products from manufacturing processes)
- Low-level radioactive waste samples
Other, supporting analyses performed in our laboratories are:
- Determination of trace amounts in various solid and liquid samples with neutron activation analysis (NAA)
- Determination of uranium concentrations in liquid samples using Time Resolved Kinetic Phosphorescence Analysis (TR-KPA)
Most of our analysis methods are accredited conform to ISO-17025. The accreditation is granted by the Belgian Accreditation organisation BELAC and is subject to a yearly audit.
- Radioactivity analysis of food and feeding stuff, including certification
- Sampling and radioactivity analysis of environmental samples
- Bio-assay measurements (nose-blow, urine, faeces)
- Low-level radioactivity analysis of samples originating in dismantling activities of nuclear installations
- Element analysis using neutron activation analysis and TR-KPA
LRM is structured in several laboratories, each specialised in a particular nuclear measurement technique and or chemical separation technique.
