A triode air system was implemented to form the electret foil. In order to calibrate the electret sensor, the ionization chamber with the electret embedded at its bottom, was placed in an emanation chamber containing radon of known concentration. The change in the effective charge density of the electret resulting from the interaction of the electret sensor with ionizing radiation, make it possible to determine the degree of its response to the radon concentration in the examined environment. The electric charge of the electret sensor was evaluated at the beginning and at the end of the concentration measurement using a field chopper. The measurement of the value of the electric field between the electret and the reference electrode directly corresponds to the effective surface charge density of the electret. The measuring system was calibrated in values of the electret equivalent voltage of U<jats:sub>z<\/jats:sub>. In order to assess the electret properties, both the thermostimulated charge relaxation (TSQ) method and the thermostimulated discharge current (TSDC) method were used to evaluate corresponding parameters. These investigations led to the optimization of the electret formation process for the maximum sensitivity to the effects of alpha particles resulting from radon radioactive decay.<\/jats:p>","DOI":"10.1155\/2019\/1705481","type":"journal-article","created":{"date-parts":[[2019,11,11]],"date-time":"2019-11-11T18:31:39Z","timestamp":1573497099000},"page":"1-9","source":"Crossref","is-referenced-by-count":2,"title":["Application of the Electret in Alpha Radiation Sensor to Measure the Concentration of Radon in Selected Ambient Conditions"],"prefix":"10.1155","volume":"2019","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5786-5548","authenticated-orcid":true,"given":"Adam","family":"Gubanski","sequence":"first","affiliation":[{"name":"Faculty of Electrical Engineering, Wroclaw University of Science and Technology, Wybrzeze Wyspianskiego 27, Wroclaw 50-370, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4426-0440","authenticated-orcid":true,"given":"Jan","family":"Kupracz","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering, Wroclaw University of Science and Technology, Wybrzeze Wyspianskiego 27, Wroclaw 50-370, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4259-9950","authenticated-orcid":true,"given":"Pawe\u0142","family":"Kostyla","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering, Wroclaw University of Science and Technology, Wybrzeze Wyspianskiego 27, Wroclaw 50-370, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2312-2903","authenticated-orcid":true,"given":"Dominika","family":"Kaczorowska","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering, Wroclaw University of Science and Technology, Wybrzeze Wyspianskiego 27, Wroclaw 50-370, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jerzy","family":"Wrobel","sequence":"additional","affiliation":[{"name":"Department of Physics and Astronomy, University of Missouri-Kansas City, 5110 Rockhill Road, Kansas City, MO 64111, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/S0969-806X(01)00310-3"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1093\/aje\/155.6.554"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/23.106733"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jenvrad.2005.04.012"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.radmeas.2008.10.009"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.rpd.a081506"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1093\/rpd\/ncl102"},{"issue":"2","key":"8","doi-asserted-by":"crossref","first-page":"250","DOI":"10.1093\/rpd\/ncl102","volume":"123","year":"2007","journal-title":"Radiation Protection Dosimetry"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/j.measurement.2016.09.002"},{"year":"1992","key":"10"},{"year":"2005","key":"11"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1590\/S0103-97331999000200009"},{"issue":"2-3","key":"13","volume":"7","year":"1981","journal-title":"Institute of Electrical Engineering Fundamentals, Technical University of Wroclaw, Materials Science"},{"year":"1979","key":"14"},{"year":"1999","key":"15"},{"issue":"14","key":"16","volume":"41","year":"2004","journal-title":"Politechnika Wroc\u0142awska, Monografie Nr"}],"container-title":["Journal of Sensors"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2019\/1705481.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2019\/1705481.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2019\/1705481.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,11,11]],"date-time":"2019-11-11T18:31:41Z","timestamp":1573497101000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/js\/2019\/1705481\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,11,11]]},"references-count":16,"alternative-id":["1705481","1705481"],"URL":"https:\/\/doi.org\/10.1155\/2019\/1705481","relation":{},"ISSN":["1687-725X","1687-7268"],"issn-type":[{"type":"print","value":"1687-725X"},{"type":"electronic","value":"1687-7268"}],"subject":[],"published":{"date-parts":[[2019,11,11]]}}}
