This study conducted a 98-day collocation of 15 models of ERMs (3 units each; 45 total) alongside a calibrated research-grade reference instrument (AlphaGuard PQ2000) and two alpha-track detectors (Radtrak\n                    <jats:sup>3<\/jats:sup>\n                    ; Radonova) in the lowest lived-in space of an occupied single-family home in Waterloo, Ontario, Canada, while concurrently recording environmental parameters, including PM\n                    <jats:sub>2.5<\/jats:sub>\n                    , CO\n                    <jats:sub>2<\/jats:sub>\n                    , temperature, and relative humidity. The average radon concentration reported by the reference instrument was 99 Bq m\n                    <jats:sup>\u22123<\/jats:sup>\n                    , with a range from 62\u2013141 Bq m\n                    <jats:sup>\u22123<\/jats:sup>\n                    . The cumulative and real-time ERM performance was assessed using a variety of metrics. Performance varied substantially across and within models. Eight out of the fifteen models had two or more units that achieved a relative percent error (RPE) within \u00b125%, with the top performers achieving an RPE of 3%\u20135% after 13 weeks of deployment, while several other devices under- or overestimated, from negative 47% to positive 220%. Most models showed acceptable intra-model repeatability with a coefficient of variation lower than 15%. For real-time performance, top-performing ERMs achieved a root mean square error of 5\u20136 Bq m\n                    <jats:sup>\u22123<\/jats:sup>\n                    , and moderate (\n                    <jats:italic>\u03c1<\/jats:italic>\n                    = 0.70\u20130.77), statistically significant Spearman-rank correlations on two-day non-overlapping averages. Overall, selected ERMs can approximate long-term cumulative average concentrations under real-world conditions, making them appropriate for long-term radon risk screening. However, the variability in ERM performance also highlights the need for regulatory oversight and independent testing to protect building occupants from a false sense of security or false alarms.\n                  <\/jats:p>","DOI":"10.1088\/1361-6498\/aea16a","type":"journal-article","created":{"date-parts":[[2026,9,2]],"date-time":"2026-09-02T22:48:16Z","timestamp":1788389296000},"page":"031533","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Cumulative and real-time performance of consumer-grade electronic radon monitors in a Canadian single-family home over three months"],"prefix":"10.1088","volume":"46","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-9549-0121","authenticated-orcid":true,"given":"Amanda","family":"Giang","sequence":"first","affiliation":[{"name":"University of Waterloo, 200 University Ave. W"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-5201-2715","authenticated-orcid":true,"given":"Alexander","family":"Lemieux","sequence":"additional","affiliation":[{"name":"Health Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pawel","family":"Mekarski","sequence":"additional","affiliation":[{"name":"Health Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6082-4608","authenticated-orcid":true,"given":"Tianyuan","family":"Li","sequence":"additional","affiliation":[{"name":"University of Waterloo, 200 University Ave. W"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2026,9,17]]},"reference":[{"key":"jrpaea16abib1","article-title":"Performance specifications for instrumentation systems designed to measure radon gas in air","author":"ANSI\/AARST","year":"2022","type":"web-resource"},{"key":"jrpaea16abib2","doi-asserted-by":"publisher","DOI":"10.1088\/1361-6498\/ad4bf1","type":"journal-article","article-title":"Evaluation of consumer digital radon measurement devices: a comparative analysis","volume":"44","author":"Bahadori","year":"2024","journal-title":"J.
