The relatively simple physico-chemical behaviour of radon gas provides a marked advantage over other tracer gases that are usually present in high concentrations in hypogeous environments, such as CO2. Two types of continuous radon measurement were undertaken. The first involves active detectors located in the Hall and Polychromes Room, which provide radon concentration values at 1-hour intervals.

The relatively simple physico-chemical behaviour of radon gas provides a marked advantage over other tracer gases that are usually present in high concentrations in hypogeous environments, such as CO2. Two types of continuous radon measurement were undertaken. The first involves active detectors located in the Hall and Polychromes Room, which provide radon concentration values at 1-hour intervals. In addition, nuclear solid track etched detectors (CR-39) are used in every chamber of the cave over 14-day exposure periods, providing average radon concentrations. In this paper we show some of the specific degassing and recharge events identified by anomalous variations in the concentration of radon gas in the Polychromes Room.

One of the main goals of the EMPIR 19ENV01 traceRadon project is to harmonize radon flux measurements based on different systems and methodologies. In the framework of the traceRadon Project, two radon flux intercomparison campaigns were carried out in October 2021 at high and at low radon source areas. Four institutions participated in the field intercomparison exercises with their own systems. Every system was based on a specific radon monitor (diffusion or pump mode) and an accumulation chamber (with manual or automatic opening). Radon fluxes were calculated by each participant using both exponential and linear fittings of the radon activity concentration measured over time within the accumulation chambers. The results of this study show mainly: (i) the exponential approach is not advisable due to the variability of the...</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/103372678" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="983caf4f9e27e0315454652b3c024c99" rel="nofollow" data-download="{"attachment_id":103396688,"asset_id":103372678,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/103396688/download_file?st=MTczMjQ1ODkxNSw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="42230775" href="https://unican.academia.edu/SantiagoCelaya">Santiago Celaya</a><script data-card-contents-for-user="42230775" type="text/json">{"id":42230775,"first_name":"Santiago","last_name":"Celaya","domain_name":"unican","page_name":"SantiagoCelaya","display_name":"Santiago Celaya","profile_url":"https://unican.academia.edu/SantiagoCelaya","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_103372678 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="103372678"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 103372678, container: ".js-paper-rank-work_103372678", });

One of the main goals of the EMPIR 19ENV01 traceRadon project is to harmonize radon flux measurements based on different systems and methodologies. In the framework of the traceRadon Project, two radon flux intercomparison campaigns were carried out in October 2021 at high and at low radon source areas. Four institutions participated in the field intercomparison exercises with their own systems. Every system was based on a specific radon monitor (diffusion or pump mode) and an accumulation chamber (with manual or automatic opening). Radon fluxes were calculated by each participant using both exponential and linear fittings of the radon activity concentration measured over time within the accumulation chambers. The results of this study show mainly: (i) the exponential approach is not advisable due to the variability of the...","publication":"International Journal of Environmental Research and Public Health","publication_with_fallback":"International Journal of Environmental Research and Public Health","downloadable_attachments":[{"id":103396688,"asset_id":103372678,"asset_type":"Work","always_allow_download":false,"scribd_thumbnail_url":"https://attachments.academia-assets.com/103396688/thumbnails/1.jpg","download_url":"https://d1wqtxts1xzle7.cloudfront.net/103396688/pdf-libre.pdf?1686816415=\u0026response-content-disposition=attachment%3B+filename%3DIntercomparison_of_Radon_Flux_Monitors_a.pdf\u0026Expires=1732462515\u0026Signature=Rhq1333hlPk5HLIzQdfrrITNM~qHd~0BZ2BSDjHTfQtE1yid4Ew9wBT3qptNR75pVOIreH7nM4BnM4PmZn7p4EbpvvduHuXct783YVHVITmuFhvef2f~Kdm-JEQveBbHkjb7NjGyn77CbFK0Ybtx~fWZRjEV7dlyIJ-9Y4pCF5c-dd4PaBNgtmuUo5v~nFUST8CjOKCg5sqJA1Vx8zvHTWZjeoV0ry~YfpMezYXqw0mNmI9YSlOGs9bK9EGPiWh17MxDHiy7QwedsD9siedUg-r2i5PiJBjWBIl5N9FtanOUDjET-PFWHs7-gaMAYs2Fc~GIskvlBI-5NzMJGQbB8g__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA","download_file_url":"https://www.academia.edu/attachments/103396688/download_file?st=MTczMjQ1ODkxNSw4LjIyMi4yMDguMTQ2&","full_thumbnail_url":"https://0.academia-photos.com/attachment_thumbnails/103396688/mini_magick20230615-1-9lrhx1.png?1686813189"}],"downloadable_attachments_with_full_thumbnails":[{"id":103396688,"asset_id":103372678,"asset_type":"Work","always_allow_download":false,"scribd_thumbnail_url":"https://attachments.academia-assets.com/103396688/thumbnails/1.jpg","download_url":"https://d1wqtxts1xzle7.cloudfront.net/103396688/pdf-libre.pdf?1686816415=\u0026response-content-disposition=attachment%3B+filename%3DIntercomparison_of_Radon_Flux_Monitors_a.pdf\u0026Expires=1732462515\u0026Signature=Rhq1333hlPk5HLIzQdfrrITNM~qHd~0BZ2BSDjHTfQtE1yid4Ew9wBT3qptNR75pVOIreH7nM4BnM4PmZn7p4EbpvvduHuXct783YVHVITmuFhvef2f~Kdm-JEQveBbHkjb7NjGyn77CbFK0Ybtx~fWZRjEV7dlyIJ-9Y4pCF5c-dd4PaBNgtmuUo5v~nFUST8CjOKCg5sqJA1Vx8zvHTWZjeoV0ry~YfpMezYXqw0mNmI9YSlOGs9bK9EGPiWh17MxDHiy7QwedsD9siedUg-r2i5PiJBjWBIl5N9FtanOUDjET-PFWHs7-gaMAYs2Fc~GIskvlBI-5NzMJGQbB8g__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA","download_file_url":"https://www.academia.edu/attachments/103396688/download_file?st=MTczMjQ1ODkxNSw4LjIyMi4yMDguMTQ2&","full_thumbnail_url":"https://0.academia-photos.com/attachment_thumbnails/103396688/mini_magick20230615-1-9lrhx1.png?1686813189"}],"has_pdf":true,"has_fulltext":true,"page_count":20,"ordered_authors":[{"id":42230775,"first_name":"Santiago","last_name":"Celaya","domain_name":"unican","page_name":"SantiagoCelaya","display_name":"Santiago Celaya","profile_url":"https://unican.academia.edu/SantiagoCelaya","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":402,"name":"Environmental Science","url":"https://www.academia.edu/Documents/in/Environmental_Science","nofollow":false},{"id":26327,"name":"Medicine","url":"https://www.academia.edu/Documents/in/Medicine","nofollow":false},{"id":28235,"name":"Multidisciplinary","url":"https://www.academia.edu/Documents/in/Multidisciplinary","nofollow":false},{"id":85038,"name":"Environmental public health","url":"https://www.academia.edu/Documents/in/Environmental_public_health","nofollow":false},{"id":130145,"name":"Advection","url":"https://www.academia.edu/Documents/in/Advection"},{"id":225942,"name":"Radon","url":"https://www.academia.edu/Documents/in/Radon"},{"id":978631,"name":"Radium","url":"https://www.academia.edu/Documents/in/Radium"}],"publication_year":null,"publication_year_with_fallback":2022,"paper_rank":null,"all_time_views":0,"active_discussion":{}}, }) } })();</script></ul></li></ul></div></div></div></div><div class="u-taCenter Pagination"></div></div></div></div></div></div></div> </div> <div class="bootstrap login"><div class="modal fade login-modal" id="login-modal"><div class="login-modal-dialog modal-dialog"><div class="modal-content"><div class="modal-header"><button class="close close" data-dismiss="modal" type="button"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button><h4 class="modal-title text-center"><strong>Log In</strong></h4></div><div class="modal-body"><div class="row"><div class="col-xs-10 col-xs-offset-1"><button class="btn btn-fb btn-lg btn-block btn-v-center-content" id="login-facebook-oauth-button"><svg style="float: left;
