Selim Khan,


These are data from 48 selected peer-reviewed articles and 13 other grey literature regarding effectiveness of radon mitigation systems installed in residential or model houses. Some of the documents described also the factors that need to be considered in installing the mitigation systems. The screened and critically appraised data were synthesized data using PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analysis) 2009 checklist. We assessed quality by using Cochrane Risk of Bias Tool for the experimental and Hamilton tool for the non-experimental and uncontrolled studies. We included 61 pieces of literature for the final review. 13 were various types of documents, and 48 were peer-reviewed articles. Among the latter, seventeen were experimental studies, three reviews, 22 quantitative, one case-control study, four case studies, one qualitative research. Among the experimental studies, fifteen were of high quality and two of moderate quality. Among 22 non-experimental quantitative studies, 15 were of high quality and 7 of moderate quality; all the case and qualitative studies were of high quality.


Steps to reproduce

We searched fifteen academic and grey literature bibliographic databases (Academic Search Complete, ACCESS Digital Library, Avery Index, CAB Abstracts, CINAHL, The Cochrane Library (OVID & Wiley), EMBASE, Erudite, Geobase, Global Health, IBSS, PubMed(Medline), PAIS, PsycINFO, Web of Science) and other websites for radon intervention studies and related documents published from 1990 to 2018. We used Medical Subject Headings( MeSH) with help from a librarian at the University of Ottawa. We used the MeSH words ‘Radon,’ ‘Testing,’ ‘Intervention,’ ‘Mitigation,’ ‘Depressurization,’ ‘Ventilation,’ ‘Effectiveness’ for the search. Besides, we searched reference lists of the selected articles and requested radon experts for any relevant documents. We did not limit the literature search by language, location and publication status.
