For a reliable use, all surface contamination monitors should have a valid calibration with traceability to the international standards. A comparison exercise for calibrations in terms of efficiency in 2\u03c0 steradian for surface contamination monitors was organized between five dosimetry calibration laboratories, members of EURAMET (The European Association of National Metrology Institutes). Four \u03b2-beta radionuclide sources, Sr-90, Cl-36, Cs-137, Co-60, and one \u03b1-alpha source, Am-241, were used for calibrations during this exercise. Two transfer surface contamination monitors, one Canberra SABG 100 and one Berthold LB 124 with 100\u00a0cm2 and 343\u00a0cm2 effective area, respectively, were used. The monitors were circulated between the partners and were periodically returned to the pilot laboratory for stability checks. The efficiencies in 2\u03c0 steradian measured by the participants do not fully agree for all sources and both detectors despite the fact that all laboratories used similar types of surface contamination sources and had proper traceability to primary standards for surface emission rate measurements. As no evident difference in measurements of surface emission rates is expected between the primary standard laboratories that calibrated the sources, it is very probable that the observed differences are mainly due to the calibration procedures used by each laboratory and that the measurement uncertainties of efficiency in 2\u03c0 steradian are underestimated. This report presents the results of this pilot comparison for calibration of surface contamination monitors and stresses the need to organize similar generalized exercises. This report also identifies some gaps in procedures for calibration of surface contamination monitors.<\/jats:p>","DOI":"10.1093\/rpd\/ncae223","type":"journal-article","created":{"date-parts":[[2024,12,10]],"date-time":"2024-12-10T18:00:45Z","timestamp":1733853645000},"page":"79-87","source":"Crossref","is-referenced-by-count":1,"title":["Comparison of calibration results for \u03b1, \u03b2 surface contamination monitors"],"prefix":"10.1093","volume":"201","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-3348-1013","authenticated-orcid":false,"given":"Liviu-Cristian","family":"Mihailescu","sequence":"first","affiliation":[{"name":"Belgian Nuclear Research Centre SCK CEN, Institute for Nuclear Medical Applications , Boeretang 200, B-2400 Mol ,","place":["Belgium"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Denis","family":"Glavi\u010d-Cindro","sequence":"additional","affiliation":[{"name":"Metrology Institute of the Republic of Slovenia - Jo\u017eef Stefan Institute, MIRS\/IJS\/F-2,O-2 , Department of Low and Medium Energy Physics, Jamova 39, SI-1000 Ljubljana ,","place":["Slovenia"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jussi","family":"Huikari","sequence":"additional","affiliation":[{"name":"STUK - Radiation and Nuclear Authority , Jokiniemenkuja 1, 01370 Vantaa ,","place":["Finland"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrej","family":"Javorn\u00edk","sequence":"additional","affiliation":[{"name":"Slovak Institute of Metrology SMU , Department of Ionizing Radiation, Karlovesk\u00e1 63, 842 55 Bratislava 4 ,","place":["Slovak Republic"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stanislav V","family":"Stanev","sequence":"additional","affiliation":[{"name":"Bulgarian Institute of Metrology BIM, Ionising Radiations Department , 10 Kubrat Str., 5500 Lovech ,","place":["Bulgaria"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2024,12,3]]},"reference":[{"key":"2025021817181218600_ref1"},{"key":"2025021817181218600_ref2","doi-asserted-by":"publisher","first-page":"06007","DOI":"10.1088\/0026-1394\/59\/1A\/06007","article-title":"Supplementary comparison of the measurement of the alpha and beta particle surface emission rates from large area sources (CCRI(II)-S10 LASCE)","volume":"59","author":"De Felice","year":"2022","journal-title":"Metrologia"},{"key":"2025021817181218600_ref3","year":"2014"},{"key":"2025021817181218600_ref4"},{"key":"2025021817181218600_ref5","volume-title":"RI(II)-S4 Technical Protocol, Protocol of an APMP supplementary comparison on large area surface emission rate measurements","author":"APMP"},{"key":"2025021817181218600_ref6","volume-title":"NPL report DQL-RN 016 \u201cThird IRMF comparison of surface contamination monitor calibrations 2004\u20132005\u201d","author":"Collins","year":"2006"},{"key":"2025021817181218600_ref7"},{"key":"2025021817181218600_ref8"},{"key":"2025021817181218600_ref9","article-title":"Non-intelligent & intelligent scintillation probes","year":"2017","journal-title":"Instruction Manual"},{"key":"2025021817181218600_ref10","volume-title":"AP6, BP17 & DP8 Wall probe, Instruction Manual","year":"2017"},{"key":"2025021817181218600_ref11","volume-title":"Contamination Monitor LB 124 SCINT Series \u2013 Operating Manual valid from software version V 4.12 DC00515BA2, Rev.
