  1. 19. INTERCOMPARISON EXERCISES AS A TOOL FOR IMPROVING THE QUALITY OF RADIOCHEMICAL MEASUREMENTS IN DRINKING WATERS
    Maurizio Forte

    Quality and Intercomparisons
    Oral Presentation

    In last years the demand of radiometric analysis of drinking waters greatly increased due to the transposition of the EU Drinking Water Directive 2013/51/Euratom (E-DWD) into national legislation of EU member states. In order to assess compliance with parametric values given by the Euratom Directive, gross alpha/beta (GAB), 3H and 222Rn measurements are basically...

    Quality and Intercomparisons
    Oral Presentation

    The ISO/IEC 17025 standard General requirements for the competence of testing and calibration laboratories, issued in November 2017, requires that laboratories must identify, evaluate and appropriately propagate all significant contributions to the measurement uncertainty, including also those arising from sampling. The common praxis with previous version of the standard was that the...

  3. 40. QA/QC AS A TOOL FOR AN IMPROVEMENT OF THE ANALYTICAL PROCESS AND CHARACTERISTIC LIMITS IN THE CASE OF DETERMINATION OF TRITIUM SPECIFIC ACTIVITY BY ELECTROLYTIC ENRICHMENT

    Quality and Intercomparisons
    Oral Presentation

    In the Laboratory for LSC, we have been measuring tritium in environmental waters since 2009 using the method of electrolytic enrichment of tritium, accredited according to ISO 17025. Each electrolytic set contains a maximum of 15 electrolyzed samples with unknown activity, 5 control - calibration electrolyzed samples and three control non - electrolyzed samples. All measurement data and...

    Quality and Intercomparisons
    Poster Presentation

    Two flagship experiments at the Center for Underground Physics (CUP), AMoRE searching for neutrinoless double beta decay and COSINE for WIMP (Weakly Interaction Massive Particle) dark matter, are rare-event search experiments running at the Yangyang underground laboratory (Y2L). It is critical to know radioactivity levels of respective detector materials to control the experiment...

    Quality and Intercomparisons
    Poster Presentation

    ABSTRACT

    A Certified Reference Material (CRM) is defined in ISO Guide 30 as a RM characterised by a metrological valid procedure for one or more specified properties (in this case content of selected radionuclides) accompanied by a certificate that provides the value of a specified properties, their associated uncertainties and statement of metrological traceability. The certificate reports...

  6. 38. AMBIENT HUMIDITY, THE OVERLOOKED INFLUENCER OF RADIOACTIVITY MEASUREMENTS
    Dr Stefaan Pommé (JRC)
    Quality and Intercomparisons
    Oral Presentation

    Science-based decision making crucially depends on the quality of the metrology from which it derives its information. Measurements with incomplete uncertainty budgets can lead to a misinterpretation about the phenomena under investigation, sometimes with fundamental implication in science and policy making. One of the most persistent misunderstandings in radionuclide metrology is the...
