Xisaabinta tirada hawo-mareenada hawada seeska.
Hawo-mareenadu waa furayaal ku yaal qaybta dhulka sare ee aasaaska kuwaas oo loo rakibay in ay hawada ka saaraan dhulka hoostiisa.
Tani waxay ka hortagtaa ururinta gaaska radon iyo muuqaalka caaryada ee dhismayaasha dhismaha.
Hawo-mareenada ama hawo-mareenada ayaa ku yaal qaybo ka soo horjeeda qaybta hoose si loo hubiyo hawo-qaadashada ugu fiican.
Waxaa lagu talinayaa in la helo hawo-mareenada sida ugu sarreeya ee suurtogalka ah ee heerka dhulka.
Wadarta guud ee hawo-mareenada waa inay ahaadaan ugu yaraan 1/400 ee aagga dhulka hoose.
Meelaha leh maaddada radon sare, saamiga waa inuu ahaadaa ugu yaraan 1/100.
