Cov neeg feem coob, cov neeg haus luam yeeb thiab cov neeg haus luam yeeb tsis sib haum, lawv xav tsis thoob tias lawv haus luam yeeb yeej muaj cov tshuaj phem. Txawm tias ntau tshaj lij yog qhov tseeb hais tias thaum nqus tau cov pa, nyob hauv lub ntsws thiab nyob ntawd.
Lead-210 (Pb-210) thiab polonium-210 (Po-210) yog cov xaim hluav taws kub hnyiab, uas muaj kev tshawb fawb pom tias muaj nyob hauv cov pa luam yeeb.
Dab tsi yog lawv thiab qhov twg lawv tuaj?
To taub Lead-210 thiab Polonium-210
Thaum uranium, ib qho ore uas tshwm sim hauv cov nqi me me, lov, qhov chaw ua si yog tso tawm li qhov radon roj rau hauv qhov chaw. Thaum muaj tshwm sim, radon gas decays sai sai, ua cov hmoov txhuas-210 (Pb-210) thiab polonium-210 (Po-210), cov pa hluavtaws (paub tias cov khoom lwj (radon decay products)).
Cov pa roj carbon dioxide yog qhov thib ob ua rau mob ntsws cancer, thov kwv yees li ntawm 21,000 tus neeg nyob hauv Tebchaws Meskas txhua txhua xyoo. Kev haus luam yeeb yog thawj zaug, nrog kwv yees li ntawm 158.080 tus neeg poob rau mob ntsws cancer txhua xyoo hauv Tebchaws Meskas
Radon roj tso tawm los ntawm cov av tuaj yeem seeb mus rau hauv vaj tse los ntawm kab nrib pleb hauv lub hauv paus. Qhov no yog kev txhawj xeeb hauv tsev uas peb siv ntau lub sijhawm. Yog tias koj txhawj xeeb txog cov pa roj radon, saib xyuas cov huab cua hauv koj lub tsev thiab, yog tias qhov zoo rau cov radon, muab qhov ntsuas qhov tso rau qhov chaw.
Radium tseem muaj nyob rau hauv phosphate chiv uas feem ntau siv hauv kev ua luam yeeb thiab pab txhawb rau qhov ntau ntawm cov khoom cua uas muaj feem sib tiv tauj nrog cov pa luam yeeb.
Yuav Ua Li Cas Lead-210 thiab Polonium-210 Tau Hauv Lub Tuam Txhab
Raws li lub sam thiaj nyob hauv cov av ntawm cov chaw luam yeeb tawm cov radon gas, cov hlau lead thiab cov tshuaj polonium ntim dawb thiab muab rau cov hmoov av ntawm cov plua tshauv uas raug coj mus rau qhov chaw ntawm cov pa luam yeeb.
Cov kab no yuav xa lawv tus kheej mus rau cov luam yeeb ntawm cov phav plaub ntawm cov plaub mos mos uas muaj daim npog hauv qab ntawm nplooj.
Nyob rau hauv no txoj kev, hluav taws xob yog thauj ntawm lub teb mus rau kev cog nroj tsuag.
Thaum muaj, cov luam yeeb yog raug ntxuav, tab sis vim cov hmoov lead-210 thiab polonium-210 yog ob qho tib si tsis sib thooj hauv dej, cov khoom tsis raug tshem tawm. Cov hmoov lead-210 thiab polonium-210 muaj nyob hauv cov khoom haus luam yeeb tiav lawm uas tawm mus rau cov neeg tau txais kev pab. Hauv cov kis ntawm cov luam yeeb, cov khoom siv no yuav nrhiav tau ib lub tsev hauv cov neeg haus luam yeeb 'ntsws.
Hauv kev tshawb nrhiav luam tawm nyob rau hauv American Journal of Public Health, cov neeg tshawb xyuas tau tshawb xyuas ntau dua 1500 cov ntaub ntawv ua lag luam luam yeeb. Lawv nrhiav tau cov ntaub ntawv qhia tias txoj kev lag luam paub txog cov teeb meem nrog polonium hauv luam yeeb tau ntev tshaj 40 xyoo. Lawv khiav nkaum lawv cov kev tshawb fawb kom cov pej xeem hauv kev tsaus ntuj ntsig txog kab mob hauv xov tooj cua.
Dab Tsi Thaum Koj Hluav Taws Xob Hauv Raug Hlau?
Raws li tus haus luam yeeb nqus pa luam yeeb, lead-210 thiab polonium-210 "stick" rau cov luam yeeb uas sau thaum sib tw ntawm cov pa tawm hauv cov ntsws hu ua bronchioles.
Cov kev tshawb fawb tau pom tias cov kab mob-210 thiab polonium-210 ua ke ntawm cov chaw no thiab dhau sij hawm tsim cov tshuaj kub kub. Hauv particular, polonium-210 emits alpha-radiation, uas yuav ua rau mob DNA heev.
Inhaling lead-210 thiab polonium-210 yog qhov uas tseem ceeb tshaj plaws rau kev mob ntsws ntawm lub ntsws vim hais tias tsim kom muaj cov tshuaj tua kab mob nyob hauv cov ntsws ntawm cov neeg haus luam yeeb yog loj hlob thiab nyob ruaj khov.
Hluav taws xob nqus mus rau hauv lub cev yog ntsuas hauv cov units hu ua rads. Kev tshawb nrhiav pom tau hais tias 15 radon ntawm polonium nyob rau hauv cov nas muaj peev xwm ua rau mob ntsws cancer. Qhov ntawd yog kwv yees li ntawm ib-tsib ntawm cov rads absorbed los ntawm ib tug neeg haus luam yeeb uas haus 2 packs ib hnub twg rau 25 xyoo.
Cov kws tshawb fawb saib ntawm lub ntsws nqaij ntawm cov neeg haus luam yeeb uas tau tuag ntawm mob ntsws cancer pom tias feem ntau, 80 rau 100 rads ntawm polonium-210 tau sau rau hauv cov ntaub so ntswg.
Kev Haus Luam Yeeb Ntxiv Cov Hluav Taws Xob (Radioactive), Too
Txhua tus neeg uas nqus pa hauv pa luam yeeb ua rau lawv lub ntsws ua rau tib co hnyav hlau uas ua rau mob ntsws cancer hauv cov neeg haus luam yeeb.
Kwv yees li ntawm 7,330 lub ntsws mob cancer hauv Teb Chaws Asmeskas hnub no yog tshwm sim los ntawm kev haus luam yeeb zaum ob.
Tsis tas li ntawd, cov co toxins no tsuas muaj ob ntawm cov tshuaj lom neeg thiab / los yog cov tshuaj carcinogenic nyob hauv cov pa luam yeeb.
Tsis txhob nco txog cov co toxins hauv cov pa luam yeeb Thaiv Thirdhand
Thaiv Thirdhand cov pa luam yeeb yog cov khoom seem ntawm cov pa luam yeeb uas nyob hauv cov huab cua thiab nyob hauv cov chaw hauv cov chaw nyob. Nws yog tag nrho cov tib co toxins uas cov pa luam yeeb thiab lwm cov neeg haus luam yeeb ua, thiab yog ib qho kev ua phem rau cov me nyuam yaus, leej twg yuav kov tau cov hniav thiab ces muab lawv cov ntiv tes tso rau hauv lawv lub qhov ncauj.
Polonium-210 tsis tuaj yeem nqus tau rau hauv lub cev los ntawm kev sib chwv nrog cov tawv nqaij los yog cov mucous membranes. Txawm li cas los xij, thaum haus luam yeeb zaum ob, nws yog thaum muaj kev nqhis dej, thiab cov pa luam yeeb thib peb, thaum noj zaub mov.
Lo Lus Ntawm
Txog hnub tim, cov kws tshawb fawb tau tshawb pom ntau tshaj 7,000 tshuaj , nrog rau 250 yam tshuaj lom thiab 70 cov kab mob carcinogenic, nyob rau hauv luam yeeb thiab luam yeeb. Qee yam chemicals yog cov tshuaj los ntawm combustion, ib txhia yog cov khoom siv uas luam yeeb siv los cuam tshuam kev saj, hlawv sijhawm, thiab ntau dua.
Luam yeeb yog lub luag hauj lwm rau ntau tshaj 440,000 tus neeg tuag nyob rau hauv Tebchaws Meskas txhua txhua xyoo. Nyob ib ncig ntawm lub ntiaj teb, tus lej nce mus txog 6 lab, suav nrog ntau tshaj li ib nrab ntawm ib lab cov neeg uas tsis haus luam yeeb uas raug cov pa luam yeeb nchav.
Cov co toxins hauv cov luam yeeb thiab cov pa luam yeeb ua rau ntau hom mob cancer, kab mob hauv lub plawv, thiab COPD. Radiation plays ib txoj haujlwm tseem ceeb thiab.
Tsis muaj kev nyab xeeb ntawm kev haus luam yeeb. Yog tias koj tsis yog neeg haus luam yeeb, tab sis raug haus luam yeeb hauv qhov chaw, koj muaj teeb meem zoo li cov neeg haus luam yeeb ua, xws li mob ntsws cancer thiab lwm yam kev mob ntsig txog kev haus luam yeeb. Txav deb ntawm cov pa luam yeeb. Thiab yog tias koj haus luam yeeb, qhov zoo tshaj uas koj tuaj yeem ua rau koj tus kheej yog txiav .
Kawm dab tsi koj yuav xav tau thaum koj txiav luam yeeb thiab koj yuav ua li cas kom txo tau qhov tsis xis nyob nrog nicotine withdrawa l. Tsis tas li, nrhiav kev pabcuam. Tsis muaj ib yam dab tsi zoo dua qhov kev pab thiab kev camaraderie uas yog thaum koj mus cuag cov neeg uas to taub txog qhov koj tab tom ua thaum koj txiav luam yeeb.
Nov yog cov kab hauv qab: tsis txhob ntshai txiav thiab txhob muab tso tawm. Yim koj pib ua ntej, qhov tsawg dua qhov kev puas tsuaj rau koj kev noj qab haus huv.
