  • Measure of very low concentrations of radionuclides

    LMRE_vignette.jpgIRSN has developed a range of measurement resources, some of which are the only resources of their kind in France, used to quantify radionuclides present at very low concentrations, or even at trace levels, in samples taken from the environment. Some of these measurement resources are found at the Environmental Radioactivity Measurement Laboratory (LMRE).
