Cov tib neeg yuav tsum tau txais thiab hnav cov cim hluav taws xob los saib xyuas qhov raug yog tias lawv: Ua haujlwm fluoroscopic x-ray units lossis ua haujlwm hauv thaj chaw uas siv fluoroscopic x-ray units. Ua haujlwm kho x-ray units. Muab tshuaj radiopharmaceuticals rau cov neeg mob.
Yuav tsum muaj cov paib hluav taws xob puas?
Txhua tus neeg siv khoom siv kho mob x-ray (C-arms, fluoro units, therapy units) yuav tsum hnav cov paib. Cov uas siv cov khoom siv hluav taws xob ntau dua yuav raug muab cov paib.
Thaum twg yuav tsum hnav daim ntawv qhia dosimeter?
Ntaus koj daim paib txhua hnub thaum ua haujlwm. Muab tso rau hauv qhov chaw tsis muaj hluav taws xob tom qab cov sijhawm ua haujlwm. Tsis txhob tshem cov paib ntawm koj qhov chaw ua haujlwm. Muab daim paib tso rau hauv lub caj dab lossis hauv siab, tig mus rau qhov chaw hluav taws xob.
Cov paib tiv thaiv hluav taws xob ua haujlwm li cas?
Daim paib hluav taws xob dosimeter tsis tiv thaiv tus neeg ua haujlwm ntawm hluav taws xob, tab sis ntes thiab ntsuas hluav taws xob uas koj tau raug nthuav tawm Daim paib yuav ntes lub zog siab beta, gamma lossis x- hluav taws xob hluav taws xob. Cov dosimeters no tsis tuaj yeem ntes cov hluav taws xob qis beta los ntawm qee cov isotopes suav nrog tritium (H-3).
Vim li cas qee tus kws saib xyuas kev noj qab haus huv hnav cov paib tiv thaiv hluav taws xob?
Note: Yog tias koj tau txais daim ntawv cim npe, koj yuav tsum hnav nws thaum twg koj ua haujlwm ze rau hluav taws xob. Cov paib no muab cov ntaub ntawv raug cai ntawm cov hluav taws xob sib txuas rau lub neej; Yog li ntawd, nws yog ib qho tseem ceeb uas lawv siv thaum muab.

Thaum twg yog lub teeb hluav taws xob tsim hluav taws xob?
Lub teeb sodium siab tsawg tau tsim ua ntej hauv 1920 los ntawm Arthur H. Compton ntawm Westinghouse. Thawj lub teeb yog lub teeb puag ncig nrog ob lub electrodes ntawm txhua sab . HPS tau tsim thaum twg? HPS teeb tau tsim thiab qhia hauv 1968 ua qhov chaw siv hluav taws xob zoo rau sab nrauv, kev ruaj ntseg, thiab kev siv teeb pom kev zoo, thiab tshwj xeeb tshaj yog nyob rau hauv kev siv teeb pom kev zoo .
Yuav ua li cas thiaj ua tau hluav taws xob hluav taws xob?
Ua raws cov kauj ruam no: Pib hlawv ntoo hauv lub lauj kaub hlau loj. Cia nws txias. Ntxhis cov hluav taws kub hnyiab. Thaum cov hluav taws qhuav, muab cov charcoal rau hauv cov hmoov zoo. Ntxiv cov calcium chloride ua ke thiab dej.
Yuav tsum tau hloov cov hluav taws xob hluav taws xob nrog cov hluav taws xob?
Kuv puas yuav tsum hloov cov hluav taws xob hluav taws xob nrog cov hluav taws xob? Ignition coils thiab spark plugs ua haujlwm zoo ua ke. … Tab sis yog tias koj tsuas yog hloov koj lub qhov hluav taws xob ua ib feem ntawm kev saib xyuas niaj hnub, nws tsis tsim nyog los hloov koj cov hluav taws xob hluav taws xob tib lub sijhawm tshwj tsis yog muaj cov cim qhia tias lawv ua tsis tau Yuav tsum hloov cov hluav taws xob hluav taws xob ntau npaum li cas?
Puas yog roj hluav taws xob hluav taws xob hluav taws xob zoo?
Central gas heating systems siv natural gas rau tsev sov. Kuv xav siv cov pa roj carbon monoxide tsis zoo rau lub hauv nruab nrab cua sov vim tias nws yooj yim, yooj yim, txhim khu kev qha, thiab ua haujlwm zoo dua. Thaum tshav kub kub uas los ntawm cov nkev ntuj pom tau tias sov dua li cua sov tawm ntawm lub hauv paus system .
Yuav tsum muaj hluav taws xob tswj hluav taws xob kub?
Power thiab Thermal Dissipation Raws li kev siv hluav taws xob nce, cov khoom xws li cov kab hluav taws xob hluav taws xob hluav taws xob tuaj yeem ua kom sov thaum lub sijhawm ua haujlwm ib txwm. Qee qhov cua sov zoo, txawm li cas los xij thaum kub dhau, qhov kev ua haujlwm ntawm cov kab hluav taws xob tswj tau raug kev txom nyem .
