RJ11-2100 Lub Tsheb Radiation Portal Monitor (RPM) feem ntau yog siv los saib xyuas yog tias muaj cov khoom siv hluav taws xob nqa los ntawm cov tsheb thauj khoom, lub thawv tsheb, tsheb ciav hlau, thiab yog tias lwm lub tsheb muaj cov khoom siv hluav taws xob ntau dhau. Lub RJ11 Tsheb RPM yog nruab nrog cov yas scintillators los ntawm lub neej ntawd, nrog sodium iodide (NaI) thiab ³He roj proportional txee raws li cov khoom xaiv. Nws nta siab rhiab heev, tsis tshua muaj kev txwv tsis pub, thiab cov lus teb ceev ceev, ua rau lub sijhawm tsis siv neeg saib xyuas ntawm ntau txoj kev hla. Ua ke nrog cov haujlwm pabcuam xws li kev kuaj xyuas lub tsheb ceev, kev soj ntsuam video, daim ntawv tso cai lees paub, thiab kev txheeb xyuas tus naj npawb ntawm cov thawv (xaiv tau), nws tiv thaiv kev thauj mus los tsis raug cai thiab kis ntawm cov khoom siv hluav taws xob. Nws yog dav siv rau radioactive saib xyuas thiab tswj ntawm kev tawm thiab nkag ntawm nuclear fais fab nroj tsuag, kev lis kev cai, tshav dav hlau, railway chaw nres tsheb, thiab lwm yam. Cov kev xaiv radionuclide identification module ua raws li cov kev cai ntawm Suav tus qauv GB / T 31836-2015 "Spectrometry-Based Portal Monitors Siv rau Kev Tshawb Fawb thiab Kev Qhia Txog Kev Ua Phem Txhaum Cai ntawm Cov Khoom Siv Hluav Taws Xob".

1. BlN (Background ldentification of Normal) Background Neglect Technology
Cov thev naus laus zis no tso cai rau kev tshawb pom kev nrawm ntawm cov khoom siv hluav taws xob qis qis txawm tias nyob hauv qhov chaw muaj hluav taws xob siab, nrog lub sijhawm kuaj pom sai li 200 milisecond. Nws tso cai rau kev tshawb nrhiav cov ntaub ntawv xov tooj cua thaum lub tsheb txav ntawm qhov nrawm, ua rau nws tsim nyog rau kev tshuaj xyuas sai. Ib txhij, nws ua kom lub cuab yeej tsis tsim lub tswb tsis tseeb vim qhov tseem ceeb ua rau muaj hluav taws xob rov qab. Tsis tas li ntawd, nws them nyiaj rau reduchion hauv keeb kwm suav tus nqi tshwm sim los ntawm kev tiv thaiv hluav taws xob ntuj thaum lub tsheb nyob hauv thaj chaw kuaj pom, txhim kho qhov tseeb ntawm cov txiaj ntsig tshuaj xyuas thiab txhim kho qhov tshwm sim ntawm kev kuaj pom. Qhov no yog ib qho txiaj ntsig zoo rau kev tshawb nrhiav cov khoom siv hluav taws xob tsis muaj zog.
2. NORM Rejection Function
Txoj haujlwm no yog siv los txheeb xyuas thiab paub qhov txawv ntawm Cov Khoom Siv Radicacive (NORM) lt pab cov neeg ua haujlwm hauv kev txiav txim siab seb lub tswb puas tshwm sim los ntawm cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob.
3. Yam ntxwv SlGMA Statistical Algorithm
Siv cov yam ntxwv SIGMA alkorithm, cov neeg siv tau yooj yim kho qhov kev sib raug zoo ntawm lub cuab yeej detecton rhiab heev thiab qhov tshwm sim ntawm lub tswb tsis tseeb Nws tso cai rau kom muaj kev nkag siab zoo kom pom cov xov tooj cua tsis tshua muaj zog (xws li, qhov chaw poob) hauv cov xwm txheej tshwj xeeb, lossis tiv thaiv lub tswb tsis tseeb thaum lub sij hawm ntev kev soj ntsuam, muab qhov tseeb.
