She developed the SIRTI, a transportable NaI(Tl) detector, well characterized and calibrated at the BIPM. Since 2009 Carine has been running the on-site SIRTI key comparisons of activity measurements for short-lived radionuclides such as <sup>99m</sup>Tc and <sup>18</sup>F.</p> <p>Since 2000, she has been the Executive Secretary and <i>Rapporteur</i> for <a class="introGras" href="/en/committees/cc/wg/jcgm-wg1.html">Working Group 1 of the Joint Committee for Guides in Metrology</a>.</p> <p>In addition to peer-reviewed publications, she is the author of more than 100 key comparison reports, of BIPM reports, and of CCRI(II) working documents, and she is co-author of one BIPM Monograph.</p> </div> </div> </div> <div class="hide"> <div class="card"> <div class="card-header" id="headingSessionCommittees"> <h5 class="mb-0 "> <button class="btn btn-link w-100 text-left" data-toggle="collapse" data-target="#session-committees" aria-expanded="false" aria-controls="collapseTwo"> Last committee meetings </button> </h5> </div> <div id="session-committees" class="collapse" aria-labelledby="headingSessionCommittees" data-parent="#accordion"> <div class="card-body"> <p class="title-third">Consultative Committee for Ionizing Radiation</p> <p>BIPM staff in attendance</p> <p> From 08 to 09 June 2023 </p> </div> <div class="card-body"> <p class="title-third">Consultative Committee for Ionizing Radiation</p> <p>BIPM staff in attendance</p> <p> From 08 to 10 June 2021 </p> </div> <div class="card-body"> <p class="title-third">Consultative Committee for Ionizing Radiation</p> <p>BIPM staff in attendance</p> <p> 07 June 2019 </p> </div> </div> </div> <div class="card"> <div class="card-header" id="headingSessionWorkingGroups"> <h5 class="mb-0"> <button class="btn btn-link w-100 text-left" data-toggle="collapse" data-target="#session-working-groups" aria-expanded="false" aria-controls="collapseTwo"> Last working group meetings </button> </h5> </div> <div id="session-working-groups" class="collapse" aria-labelledby="headingSessionWorkingGroups" data-parent="#accordion"> <div class="card-body"> <div class="person-info"> <p class="title-third">CCRI Section II: Measurement of radionuclides</p> <p>BIPM staff in attendance</p> <p> From 05 to 07 June 2023 </p> </div> </div> <div class="card-body"> <div class="person-info"> <p class="title-third">CCRI Section II: Key Comparisons Working Group</p> <p>BIPM staff in attendance</p> <p> 24 May 2023 </p> </div> </div> <div class="card-body"> <div class="person-info"> <p class="title-third">JCGM Working Group on the Expression of Uncertainty in Measurement</p> <p>Executive Secretary</p> <p> From 09 to 12 May 2023 </p> </div> </div> </div> </div> </div> <div class="card"> <div class="card-header" id="headingRelatedPublications"> <h5 class="mb-0"> <button class="btn btn-link w-100 text-left" data-toggle="collapse" data-target="#related-publications" aria-expanded="false" aria-controls="collapseTwo"> Recent publications </button> </h5> </div> <div id="related-publications" class="collapse" aria-labelledby="headingRelatedPublications" data-parent="#accordion"> <div id="_person_info_portlet_publication_tabs_nav"> <ul class="nav nav-justified nav-pills navbar-site"> <li class="lfr-nav-item nav-item active index-0"> <a href="#" onclick="selectOnglet(0)" class="nav-link">Miscellaneous</a> </li> <li class="lfr-nav-item nav-item index-1"> <a href="#" onclick="selectOnglet(1)" class="nav-link">Metrologia</a> </li> <li class="lfr-nav-item nav-item index-2"> <a href="#" onclick="selectOnglet(2)" class="nav-link">Rapports BIPM</a> </li> </ul> </div> <div id="_person_info_portlet_publication_tabs_content"> <div id="_person_info_portlet_publications_tab_0" class="publications-tab index-0 active"> <div class="card-body"> <a href="https://doi.org/10.1038/s41567-023-02166-5" target="_blank"> <p class="title-third">Radionuclide activities<p> </a> <p>Nat.
