Kev Ntsuam Xyuas Radon

Peb nquag kuaj peb lub tsev kawm ntawv rau radon, ib tug xim ntxhiab, odorless roj uas yeej tawm los ntawm av thiab muaj tau txuas rau qee cov neeg tuag thaum nyob elevated. Thaum kuaj radon kuaj tsis tas yuav txhaj rau cov tsev kawm ntawv hauv Minnesota, peb lub cheeb tsam tsev kawm ntawv tau kuaj peb cov tsev kawm ntawv rau radon thiab peb muaj mitigated tej teeb meem thaum lawv sawv. Qhov tseeb muab kev kuaj ntawd nyob rau xyoo 2018-2019.

Kev kuaj no tsis ntev los no
Kev ntsuam xyuas yav dhau los

Kev kuaj no tsis ntev los no

Tsim radon kuaj rau tag nrho peb vaj tse muab qhov chaw nyob rau xyoo 2018-2019 thaum lub MN Department of Health pom zoo timeframe ntawm kaum ib hlis 1 mus txog rau lub peb hlis ntuj 31. Qhov kev kuaj ntawd yog ua los ntawm daim teb consulting, siv MN Department of Health Radon hauv tsev kawm ntawv qauv:

843 kuaj canisters tau tsom xam. Ob tug muaj pib radon concentrations saum 4.0 pci/L:

Yuav Lake Classroom 205 = 4.1 pci/
Stillwater Middle School Office 189W = 7.5 p/L

Raws li kev kuaj hauv cov chav tsev tsom concentrations zoo hauv qab tes hauj lwm:

Yuav Tsis Zoo Li Cov Chav Kawm Ntawv 2005 = 1.8 p.8 p/L
Stillwater Middle School Office 189W = .6 p/L

Nyob rau hauv Minnesota Department of Health, tsis xav kuaj/mitigation yog tsim nyog. 2018-2019-2019 cov qhabnias rau cov tsev kawm ntawv thiab vaj tse nrhiav tau hauv qab no:

Kev ntsuam xyuas yav dhau los

Peb sib cog lus nrog ib puag nrho tus neeg pab tswv yim los mus kuaj tas nrho peb vaj tse rau radon hauv xyoo 2006-2007 thiab ua tau raws li kev kuaj hauv xyoo 2008 rau vaj tse uas muaj kom radon radon. Vim li ntawd lub hauv paus chiv keeb thiab ua raws li kev kuaj, radon mitigation systems tau ntsia tom Marine Elementary nyob rau lub caij nplooj zeeg xyoo 2008 thiab lub pas dej Elmo nyob rau lub caij nplooj ntoos hlav ntawm xyoo 2009. Ua raws li kev kuaj hauv kev koom tes nrog MN Department of Health nyob rau xyoo 2010 thiab xyoo 2011 paub tseeb hais tias cov theem elevated Tau qis hauv qab no tej kev tiv thaiv uas lub koom haum qhia ntawv ntawm 4 p/L (picocuries ib daim ntawv teev cov pa).

Thaum lub xyoo 2012-2013 kawm ntawv peb cov neeg ua haujlwm kuaj andersen, Pas dej Elmo thiab Marine Elementary siv cov xov tooj radon xyuas li ntawm MN Department of Health. Cov kev ntsuam xyuas tau coj mus saib xyuas hauv koog tsev kawm ntawv ntsia radon mitigation systems. Thaum ntawd, cov chaw uas cov chaw muaj kom ntau ntau radon.

• Tsis muaj dej haus

Peb lub cheeb tsam raws li lub xeev cov qauv rau kev txo cov hlau lead hauv haus dej. Qhov no saib kuas txhua lub tsev yuav tau kuaj rau cov hmoov txhuas nyob rau hauv cov dej haus tsawg kawg yog tsib xyoos thiab soj ntsuam tag nrho cov kev sib txuas lus nrog pej xeem. Cov qhabnias tsis ntev los no nyob rau xyoo 2018-2019 muaj nyob hauv qab no. Tus tom ntej muab kev tshuaj ntsuam no yuav ua kom tiav thaum lub xyoo 2023-2024 lub xyoo kawm ntawv.

Yam Tseeb: Ib Lub Koom Haum Minnesota Department of Health, cov hmoov txhuas nyob rau hauv dej nyob rau hauv cov hlau lead hauv cov dej haus taus. Cov "on-on-again, off-again" dej siv cov qauv ntawm cov tsev kawm ntawv yuav ua rau kom ntau nyob rau hauv haus. Qhov no tej zaum yuav muaj qhov tshwm sim heev ntawm cov qhabnias tau pom muaj nyob rau hauv lub tsev. Per the Facilities Manager, cov forty-one-one (41) twj ywm yuav tsum ntxuav (i.e. aerators/screens) thiab resampled. Nyob rau hauv lub meantime, cov taps tau cim "dej tsis haus."
Hloov tshiab: aerators tau ntxuav rau forty-one(41) dej outlets. Qhov no txo cov hlau lead hauv qab no rau theem ntawm 20 ppb rau kwv yees li ib nrab ntawm cov fixtures. Txawm li ntawd los, tom qab uas cia cov dej khiav rau 30 vib nas, ua concentrations yuav txo tau qib rau tag nrho fixtures. Yog li ntawd, flushing ua ntej mus noj yog ib txoj kev uas yuav ua rau kom txhob raug tus kab mob no. Mus sij hawm ntev, tus Manager of Facilities thiab Site kev khiav hauj lwm yuav txheeb xyuas rau ib tug neeg fixture thiab tom qab kab pipping peb tes num hloov peb tes num nyob rau lub caij ntuj sov.

Cov Lus Qhia Ntxiv Txog Dej Kev Nyab Xeeb

Cov hlau lead hauv dej yog ntawm kev xyaum leeching los ntawm cov peeb zeej, pipping thiab brass fixtures. Cov dej ntev stands nyob rau hauv ib lub kaw lus plumbing, ntau dua tej zaum kuj yuav ua rau cov hmoov txhuas nyob rau hauv ib cov dej mov. Nws txhais tau tias plumbing fixtures uas zaum unused thaum hmo ntuj thiab rau cov hnub so yuav muaj ntau dua ua rau cov dej mov.

Raws li MDH, virtually tag nrho cov hlau lead uas muaj tus kab mob no nyob rau tom tsev. Peb xav kom tsev neeg ua paub txog qhov uas yuav raug lawv lub tsev. Koj yuav nrhiav tau cov lus qhia ntxiv txog kev ruaj ntseg ntawm Minnesota Department of Health.
