“…There are several approaches to evaluate F based on the alpha/beta ratio or on the time behaviour of the gross beta activity for the progeny. The former does not require the measurement of the radon concentration, but it is affected by the uncertainties of the a activity (10,11) , due to selfabsorption and to the very fast decay of 218 Po (t 1/2 ¼ 15 min) (12,13) . The latter, adopted here, presumes the measurement of the radon concentration but is expected to be robust.…”

“…Actually, radon progeny emits β , γ as well as α particles. Due to the quick development of gamma spectrometry and beta spectrum analysis technology, there appeared some methods like “ β count” method [ 14 , 15 ], “ α - γ spectra” method [ 16 ], and “ α - β count method” [ 17 ]. Although those methods are not widely used in commercial device, they give us a cue to improve our current method.…”

“…A radioaktív bomlások során radioaktív (jelen esetben alfa-sugárzó) leányelemek keletkeznek, melyek a légtérben lévő parányi porszemekre, dohányfüstre ráülve bejutnak a tüdőbe, és ott megtapadva folyamatosan alfa-sugárzással bombázzák a tüdőszövetet, rákkeltő hatása van. (ABUMURAD, 2001;BUTKUS et al, 2005;ICRP 1991;ICRP 1993;KATONA et al, 2007;KÖTELES, 2007;LÁZÁR et al;SZABÓ et al, 2014b;SZERBIN et al, 1994;TÓTH, 1992;TÓTH et al, 1998;TÓTH-HÁMORI, 2005;UNSECAR, 2000) Számos kutatás foglalkozik a halálozási okok élén szereplő daganatos betegségek okainak vizsgálatával. DARBY et al (2005) szerint az Európai Bizottság által támogatott kutatásainak eredményei alapján az otthonok levegőjében található radon felelős évente körülbelül 20000 tüdőrák okozta halálesetért az Európai Unióban, ami az összes ilyen jellegű halálesetek 9%-a, illetve az összes halálos kimenetelű rákbetegségek 2%-a.…”
