Av disse finnes det tre isotoper som er spesielt interessante med tanke p\u00e5 str\u00e5levern, torium-232, uran-235 og uran-238. Felles for disse er at de har lang halveringstid og at de i nedbrytningskjeden (til stabile stoffer) omdannes til edelgassen radon. Siden en edelgass i liten grad reagerer med andre stoffer kan radonet spres fra byggegrunnen til inneluften.<\/p>\n<h3>\u00c5rsak til mange tilfeller av lungekreft<\/h3>\n<p>Radonet er radioaktivt og danner ved nedbrytningen s\u00e5kalte radond\u00f8tre. Disse er ladede metallioner som har en tendens til \u00e5 reagere og feste seg til st\u00f8vpartikler og aerosoler (sm\u00e5 finfordelte partikler). Ogs\u00e5 radond\u00f8trene er radioaktive og avgir alfastr\u00e5ling ved nedbrytning. De ubundne radond\u00f8trene som finnes i luften vi puster inn er spesielt skadelige, siden de har en tendens til \u00e5 feste seg i luftveier og lunger.<\/p>\n<p>Alfastr\u00e5lingen som avgis inni kroppen er skadelig og kan gi opphav til skader p\u00e5 vevet, som i sin tur kan f\u00f8re til lungekreft. WHO ansl\u00e5r antallet krefttilfeller som skyldes eksponering for radongass til cirka 230\u00a0000 per \u00e5r.<\/p>\n<\/div><\/section><br \/>\n<div  class='avia-button-wrap avia-button-left  avia-builder-el-10  el_after_av_textblock  avia-builder-el-last ' ><a href='https:\/\/radonova.no\/hva-er-radon\/alt-du-trenger-a-vite-om-radon-i-boligen-din\/' class='avia-button av-jv2hz2yk-09cc43ccb1795724d9acc1b54b695c6b avia-icon_select-yes-left-icon avia-size-small avia-position-left avia-color-theme-color' target=\"_blank\" rel=\"noopener noreferrer\"><span class='avia_button_icon avia_button_icon_left' aria-hidden='true' data-av_icon='\ue835' data-av_iconfont='entypo-fontello'><\/span><span class='avia_iconbox_title' >Les mer om radon, skadevirkninger av radon samt grenseverdier for arbeidsplasser og boliger<\/span><\/a><\/div><\/p><\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-1ah4cp-49ce44bd0ab6c526143c28ca6565f782\">\n.flex_column.av-1ah4cp-49ce44bd0ab6c526143c28ca6565f782{\nborder-width:1px;\nborder-color:#dddddd;\nborder-style:solid;\nborder-radius:3px 3px 3px 3px;\n-webkit-border-radius:3px 3px 3px 3px;\n-moz-border-radius:3px 3px 3px 3px;\npadding:10px 10px 10px 10px;\nbackground-color:#f0f0f0;\n}\n<\/style>\n<div class='flex_column av-1ah4cp-49ce44bd0ab6c526143c28ca6565f782 av_one_half  avia-builder-el-11  el_after_av_one_half  avia-builder-el-last  flex_column_div column-top-margin'   ><section  class='av_textblock_section av-jv2ha9oj-6d35b2ff7e76699d5a1fc36ea7d83390'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><h3>Om ulike radonisotoper<\/h3>\n<p>Radon-219 kalles ogs\u00e5 \u00abactinon\u00bb og er den radonisotopen som dannes i nedbrytningskjede fra uran-235. Siden den har en halveringstid p\u00e5 kun fire sekunder, p\u00e5treffes den ikke i innemilj\u00f8. Den rekker rett og slett ikke \u00e5 bli transportert som edelgass fra byggegrunnen til inneluft f\u00f8r den brytes ned til polonium-215.<\/p>\n<p>Radon-222 stammer fra uran-238 og er den isotopen man vanligvis tenker p\u00e5 n\u00e5r man snakker om og arbeider med radon. Halveringstiden er nesten fire dager (3,8 d\u00f8gn), noe som gir gassen god tid til \u00e5 spre seg til inneluften. P\u00e5 den m\u00e5ten kan den ved en viss konsentrasjon utgj\u00f8re en helserisiko for mennesker som oppholder seg i det aktuelle innemilj\u00f8et. Radon-222 brytes ned til polonium-218, som er en alfastr\u00e5ler med en energi p\u00e5 6,00 MeV.<\/p>\n<h3>Vanlige feil n\u00e5r man m\u00e5ler radon<\/h3>\n<h4>Med instrument<\/h4>\n<ul>\n<li>Instrumentet er ikke kalibrert<\/li>\n<li>Man tar ikke hensyn til at radond\u00f8tre m\u00e5 d\u00f8 ut i m\u00e5lekammeret f\u00f8r ny m\u00e5ling gjennomf\u00f8res<\/li>\n<li>Man flytter instrumentet for raskt mellom ulike m\u00e5lepunkter<\/li>\n<li>Man avventer ikke jamvekten mellom radongassen og radond\u00f8trene<\/li>\n<\/ul>\n<h4>Med passive detektorer<\/h4>\n<ul>\n<li>Sporfilmene plasseres p\u00e5 feil sted<\/li>\n<li>Man m\u00e5ler for f\u00e5 punkter<\/li>\n<li>Man sender ikke sporfilmene inn til analyse umiddelbart etter avsluttet m\u00e5ling<\/li>\n<li>Sporfilmene analyseres av et ikke-akkreditert laboratorium<\/li>\n<\/ul>\n<\/div><\/section><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v20.13 -
