Nyob rau hauv ib lub sijhawm uas kev ruaj ntseg thiab kev nyab xeeb yog qhov tseem ceeb, qhov kev xav tau ntawm kev ntsuas hluav taws xob zoo yeej tsis yog qhov tseem ceeb dua. Ib qho ntawm cov cuab yeej tseem ceeb tshaj plaws hauv lub npe no yogRadiation Portal Monitor (RPM).Cov cuab yeej ntse no ua lub luag haujlwm tseem ceeb hauv kev tshawb nrhiav thiab txheeb xyuas cov khoom siv hluav taws xob, kom ntseeg tau tias tib neeg thiab ib puag ncig muaj kev nyab xeeb los ntawm kev phom sij. Hauv tsab xov xwm no, peb yuav tshawb xyuas seb lub tshuab hluav taws xob saib xyuas hluav taws xob ua haujlwm li cas, nws cov khoom, thiab nws qhov tseem ceeb hauv ntau daim ntawv thov.
To taub Radiation Portal Monitors
Radiation Portal Monitors yog cov tshuab tshwj xeeb tsim los kuaj pom gamma thiab neutron hluav taws xob thaum tib neeg lossis tsheb hla dhau lawv. Cov saib xyuas no feem ntau yog ntsia rau ntawm qhov chaw muaj tswv yim xws li kev hla ciam teb, tshav dav hlau, thiab chaw nuclear. Lub hom phiaj tseem ceeb ntawm RPM yog txhawm rau txheeb xyuas kev lag luam txhaum cai ntawm cov khoom siv hluav taws xob, xws liCesium-137, uas tuaj yeem ua rau muaj kev hem thawj rau pej xeem kev nyab xeeb.
Cheebtsam ntawm Radiation Portal Monitor
Ib tug raug hluav taws xob portal saib muaj ob peb yam tseem ceeb uas ua hauj lwm ua ke los xyuas kom meej kom paub tseeb thiab ntsuas ntawm cov hluav taws xob theem:
1. Kev Ntsuas Sensors: Lub plawv ntawm ib qho twgRPMyog nws nrhiav tau sensors. Cov sensors no yog tsim los ntsuas qhov kev siv hluav taws xob tawm ntawm cov khoom uas hla lub portal. Cov hom sensors siv nyob rau hauv RPMs muaj xws li scintillation detectors, yas scintillators los ntes γ rays, nrog ib co kuj nruab nrog sodium iodide (NaI) thiab He-3 roj proportional counters rau nuclide identification thiab neutron detection. Txhua hom muaj nws qhov zoo thiab raug xaiv raws li cov kev cai tshwj xeeb ntawm kev saib xyuas ib puag ncig.
2. Data Processing Unit: Thaum cov sensors ntes tau hluav taws xob, cov ntaub ntawv raug xa mus rau chav ua haujlwm. Chav tsev no txheeb xyuas cov teeb liab tau txais los ntawm cov sensors thiab txiav txim siab seb cov hluav taws xob hluav taws xob puas dhau qhov pib ua ntej. Chav tsev ua haujlwm tau nruab nrog algorithms uas tuaj yeem sib txawv ntawm cov hluav taws xob tom qab ib txwm muaj thiab muaj feem cuam tshuam rau cov hluav taws xob.
3. Tswb System: Yog hais tias lub tsev ua cov ntaub ntawv txheeb xyuas cov hluav taws xob ntau tshaj qhov kev nyab xeeb, nws ua rau lub tswb. Lub tswb no tuaj yeem ua rau pom (xws li lub teeb nyem) lossis hnov tau (xws li sirens), ceeb toom cov neeg ua haujlwm ruaj ntseg los tshawb xyuas ntxiv. Lub tswb system yog ib qho tseem ceeb tivthaiv, vim nws ua kom muaj kev teb sai rau cov kev hem thawj.
4. User Interface: Feem ntau RPMs tuaj nrog tus neeg siv interface uas tso cai rau cov neeg siv los saib xyuas cov ntaub ntawv hauv lub sijhawm, tshuaj xyuas cov ntaub ntawv keeb kwm, thiab teeb tsa. Qhov kev sib txuas no yog qhov tseem ceeb rau kev ua haujlwm zoo thiab pab cov neeg ua haujlwm txiav txim siab raws li cov ntaub ntawv khaws tseg.
5. Fais fab mov: Radiation portal saib yuav tsum muaj lub hwj chim txaus ntseeg kom ua haujlwm zoo. Ntau lub RPMs niaj hnub no tau tsim los ua haujlwm ntawm cov qauv hluav taws xob hluav taws xob, tab sis qee qhov kuj tseem suav nrog cov roj teeb thaub qab los xyuas kom muaj kev ua haujlwm tas mus li thaum lub hwj chim tawm.
Radiation Portal Monitors ua haujlwm li cas
Kev ua haujlwm ntawm a hluav taws xob portal saib tuaj yeem faib ua ob peb kauj ruam tseem ceeb:
1. Kev kuaj pom: Raws li ib tug neeg lossis lub tsheb mus txog RPM, cov ntsuas ntsuas ntsuas pib ntsuas cov hluav taws xob hluav taws xob tawm ntawm qhov khoom. Cov sensors tsis tu ncua scan rau gamma thiab neutron hluav taws xob, uas yog hom hluav taws xob feem ntau cuam tshuam nrog cov khoom siv hluav taws xob.
2. Kev txheeb xyuas cov ntaub ntawv: Cov teeb liab tau txais los ntawm kev kuaj pom tau raug xa mus rau chav ua cov ntaub ntawv. Ntawm no, cov ntaub ntawv raug tshuaj xyuas hauv lub sijhawm. Lub tsev ua haujlwm sib piv cov qib hluav taws xob uas tau pom los ntawm cov qauv tsim los txiav txim siab seb cov qib twg zoo li qub lossis qhia tau tias muaj kev hem thawj.
3. Tswb Activation: Yog tias cov hluav taws xob ntau tshaj qhov kev nyab xeeb, cov ntaub ntawv ua haujlwm ua kom lub tswb nrov. Qhov kev ceeb toom no ua rau cov neeg ua haujlwm ruaj ntseg ua haujlwm tam sim ntawd, uas yuav suav nrog kev tshuaj xyuas ntxiv ntawm tus neeg lossis lub tsheb uas nug.
4. Teb thiab Kev Tshawb Fawb: Thaum tau txais lub tswb, cov neeg ua haujlwm tau txais kev cob qhia feem ntau yuav ua qhov kev tshuaj xyuas thib ob uas siv cov khoom siv hluav taws xob ntes hluav taws xob. Cov kauj ruam no yog qhov tseem ceeb rau kev lees paub qhov muaj cov khoom siv hluav taws xob thiab txiav txim siab cov lus teb tsim nyog.
Daim ntawv thov ntawm Radiation Portal Monitors
Radiation portal saib yog ua haujlwm nyob rau hauv ntau qhov chaw, txhua tus nrog nws cov kev cai tshwj xeeb thiab cov nyom:
1. Ciam Teb Kev Nyab Xeeb:RPMsfeem ntau yog siv nyob rau hauv ciam teb thoob ntiaj teb los tiv thaiv kev nyiag khoom ntawm cov khoom siv hluav taws xob. Lawv pab kev lis kev cai thiab cov chaw tiv thaiv ciam teb txheeb xyuas cov kev hem thawj ua ntej lawv nkag mus rau hauv lub tebchaws.
2. Nuclear Facilities: Hauv cov chaw tsim hluav taws xob nuclear thiab cov chaw tshawb fawb, RPMs yog qhov tseem ceeb rau kev saib xyuas kev txav ntawm cov khoom. Lawv xyuas kom meej tias cov khoom siv hluav taws xob muaj kev nyab xeeb thiab tiv thaiv kev nkag mus tsis tau.
3. Chaw Thauj Mus Los: Cov tshav dav hlau thiab chaw nres nkoj siv RPMs los tshuaj xyuas cov khoom thauj thiab cov neeg caij tsheb rau cov khoom siv hluav taws xob. Qhov no tseem ceeb tshwj xeeb hauv cov ntsiab lus ntawm kev ruaj ntseg thoob ntiaj teb thiab kev tiv thaiv kev ua phem.
4. Cov Txheej Txheem Hauv Pej Xeem: Kev sib sau loj, xws li kev hais kwv txhiaj lossis kev sib tw kis las, kuj tseem yuav ntiav RPMs los xyuas kom muaj kev nyab xeeb ntawm cov neeg tuaj koom. Cov saib xyuas no pab tshawb xyuas txhua yam kev hem thawj uas tuaj yeem tshwm sim los ntawm muaj cov khoom siv hluav taws xob.
Radiation portal saib yog cov cuab yeej tseem ceeb hauv kev siv zog txuas ntxiv los tiv thaiv pej xeem kev noj qab haus huv thiab kev nyab xeeb. Los ntawm kev txheeb xyuas thiab txheeb xyuas cov khoom siv hluav taws xob zoo,RPMsua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev lag luam txhaum cai ntawm cov khoom txaus ntshai. Kev nkag siab txog qhov kev saib xyuas no ua haujlwm li cas, los ntawm lawv cov khoom siv rau lawv cov ntawv thov, qhia txog lawv qhov tseem ceeb hauv lub ntiaj teb uas kev nyab xeeb yog qhov tseem ceeb tshaj plaws. Raws li kev siv thev naus laus zis txuas ntxiv mus, peb tuaj yeem cia siab tias cov tshuab hluav taws xob tshawb pom yuav ua kom zoo dua qub, ntxiv dag zog rau peb lub peev xwm los tiv thaiv peb tus kheej thiab peb ib puag ncig los ntawm cov teeb meem hluav taws xob.
