  1. 1. Evolution of traceable Radon emanation sources from MBq to few Bq

    Oral Presentation

    In the framework of the EMPIR project traceRadon$^{1}$ stable atmospheres with low-level, activity concentrations of radon have to be produced for calibration of radon detectors capable of measuring outdoor air activity concentrations. The traceable calibration of these detectors at very low activity concentrations is of special interest, for the radiation protection community, as well as the...

    Oral Presentation

    The implementation of Directive 2013/59/EURATOM and the related modifications to national laws establishing reference levels of radon activity concentration, contributed to the increased interest in accurate radon measurements. Therefore, there was a need for calibration of radon instruments at reference concentrations below 300 Bq/m$^3$ with quality assured procedures and uncertainties that...

    Noble gases
    Oral Presentation

    Future liquid xenon detectors require unprecedented low levels of intrinsic radioactive backgrounds. Particularly $^{222}$Rn and its subsequent decay products represent threatening background sources for the sensitivity of such experiments. Therefore, extensive radon screening campaigns, as well as studies on novel approaches for radon mitigation, need to be carried out. They both crucially...

    Oral Presentation

    In rare event search experiments, activation of detector materials can lead to significant backgrounds. Typically, trace radioactive contaminants are activated by cosmic-ray interactions while the detector materials are being stored or transported above ground. In highly sensitive experiments, these cosmogenic backgrounds can limit sensitivity. It is therefore necessary to determine the...

  5. 17. ALGORITHMS DEVELOPMENT FOR LOW LEVEL RADIOXENON SPECTRUM ANALYSIS
    Antoine CAGNIANT (CEA)

    Noble gases
    Poster Presentation

    Underground or underwater nuclear tests can eventually lead to radioxenon releases in the atmosphere. In this scope, the verification regime of the Comprehensive nuclear Test Ban Treaty installed dedicated noble gas systems for the detection of low-level radioxenon activity in the air.
    Recent development of these noble gas systems included new detector technologies. They exhibits very low...

  6. 103. High sensitivity Rn measurements at Canfranc

    Noble gases
    Poster Presentation

    At Laboratorio Subterraneo de Canfranc (LSC, Spain) are working two detectors designed to precisely measure low concentrations of Rn. The Electrostatic Rn Monitor (ERM) can measure Rn at a level of 1mBq/m3. Right now, it is measuring the air coming from the Radon Abatement System. The Cryogenic Radon Detector is a detector designed to detect the emanated Rn with a precision in the order of...
