    Title
    Contra-expertise op bepalingen van radioactiviteit in afvalwater en ventilatielucht van COVRA N.V. : Periode 2017
    Translated Title
    Contra-expertise on the determination of radioactivity in waste water and ventilation air of COVRA N.V. : Period 2017
    Publiekssamenvatting
    De Centrale Organisatie voor Radioactief Afval (COVRA) meet hoeveel radioactiviteit in afvalwater en ventilatielucht wordt geloosd. Het RIVM controleert deze metingen acht keer per jaar. Met deze 'contra-expertise' controleert het RIVM of de analyses die COVRA zelf uitvoert, betrouwbaar zijn. De te analyseren monsters worden verspreid over het jaar door COVRA genomen. Net als in voorgaande jaren komen de gamma-analyses van afvalwater uit de contra-expertise in 2017 op hoofdlijnen overeen met de resultaten van de COVRA. De analyses van het RIVM en COVRA in de gamma-spectrometrische resultaten, de resultaten van de totaal-alfa bepaling, tritiumbepaling en de 14C-bepaling in afvalwater kwamen redelijk tot goed overeen. Hoewel het RIVM en COVRA verschillende meetprincipes gebruiken, komen de totaal bèta-meetwaarden van het RIVM en de rest bèta-meetwaarden van COVRA in 2017 goed overeen. Ook kwamen de resultaten van het RIVM en COVRA van de ventilatieluchtmonsters van het Afvalverwerkingsgebouw (AVG) en het Hoogradioactief Afval Behandelings- en Opslag Gebouw (HABOG) goed overeen. Het RIVM voert de contra-expertises jaarlijks uit in opdracht van de Autoriteit Nucleaire Veiligheid en Stralingsbescherming (ANVS).
    The Central Organisation for Radioactive Waste (COVRA) measures the release of radioactivity into waste water and atmosphere. The RIVM performs eight times per year a contra expertise on these measurements. This form of contra expertise is aimed at verifying and supporting the reliability of the analyses carried out by COVRA. The samples of wastewater and ventilation air are taken by COVRA at various time points dispersed throughout the year. The two different sets of measurements are generally in agreement, as is also the case in 2017. The agreement in the results for gamma-emitters, gross alpha, tritium and C-14 was mostly good. Considering the fact that RIVM and COVRA apply different measuring principles the agreement in the gross beta results in waste water is good. In ventilation air samples of the waste treatment building (AVG) the results for gross alpha and gross beta, 3H and 14C obtained by RIVM and COVRA are generally in good agreement. In ventilation air samples from the high activity waste storage building (HABOG) the agreement was also good. RIVM carried out this contra expertise on behalf of the Authority for Nuclear Safety and Radiation Protection (ANVS).
