Lub ntsuas hluav taws xob ntawm tes, tseem hu ua lub ntsuas hluav taws xob ntsuas hluav taws xob, yog lub cuab yeej nqa tau siv los ntsuas thiab kuaj pom muaj hluav taws xob nyob hauv ib puag ncig.Cov cuab yeej no yog cov cuab yeej tseem ceeb rau cov kws tshaj lij ua haujlwm hauv thaj chaw xws li nuclear zog, kev saib xyuas kev noj qab haus huv, kev saib xyuas ib puag ncig, thiab cov lus teb thaum muaj xwm txheej ceev, nrog rau cov tib neeg muaj kev txhawj xeeb txog qhov muaj peev xwm raug hluav taws xob.
Yog li, ua li cas ahandheld radiation meterua hauj lwm?Cov cuab yeej no ua haujlwm raws li cov hauv paus ntsiab lus ntawm kev ntsuas hluav taws xob thiab ntsuas.Muaj ntau ntau hom hluav taws xob ntsuas hluav taws xob, txhua tus siv cov thev naus laus zis sib txawv los ntsuas thiab ntsuas hluav taws xob.Ib hom yog Geiger-Muller (GM) ntes, uas muaj lub raj roj uas ua rau hluav taws xob pulse thaum hluav taws xob cuam tshuam nrog cov roj molecules hauv lub raj.Lwm hom yog lub ntsuas hluav taws xob scintillation, uas siv cov siv lead ua uas emits lub teeb thaum ntaus los ntawm hluav taws xob hais.Tsis tas li ntawd, cov khoom siv hluav taws xob semiconductor, xws li cov siv silicon lossis germanium, kuj yog siv hauv cov ntsuas hluav taws xob ntawm tes.
Thaum hluav taws xob cuam tshuam nrog lub ntsuas, nws tsim cov teeb liab uas tau ua tiav thiab tso tawm rau ntawm lub cuab yeej lub vijtsam.Cov kev nyeem ntawv feem ntau suav nrog cov koob tshuaj hluav taws xob, qhia hauv chav xws li microsieverts ib teev (µSv / h), nrog rau tag nrho cov koob tshuaj ntau tshaj ib lub sijhawm.Qee cov cuab yeej hluav taws xob hluav taws xob qib siab kuj tseem tuaj yeem muab cov ntaub ntawv hais txog hom hluav taws xob kuaj pom, xws li alpha, beta, lossis gamma hluav taws xob.
Ntxiv nrog rau kev kuaj xyuas thiab ntsuas hluav taws xob, lub ntsuas hluav taws xob ntawm tes tau tsim los ua tus neeg siv khoom zoo thiab nqa tau yooj yim.Lawv tau nruab nrog ntau yam nta los txhim kho lawv txoj haujlwm thiab yooj yim ntawm kev siv.Ntau tus qauv muaj cov qauv tsim compact thiab hnav, ua rau lawv yooj yim nqa thiab khiav lag luam hauv ntau qhov chaw.Lawv feem ntau suav nrog cov duab digital uas qhia txog cov hluav taws xob hauv lub sijhawm tiag tiag, nrog rau cov suab nrov thiab pom lub tswb kom ceeb toom tus neeg siv rau qhov muaj feem cuam tshuam hluav taws xob.Qee cov khoom siv kuj muaj peev xwm sau cov ntaub ntawv, tso cai rau cov neeg siv sau thiab txheeb xyuas qhov ntsuas hluav taws xob nyob rau lub sijhawm.
Cov kev siv ntawmhandheld radiation metersmuaj ntau haiv neeg thiab dav.Hauv kev lag luam hluav taws xob nuclear, cov cuab yeej no tau siv los saib xyuas cov qib hluav taws xob hauv cov chaw tsim hluav taws xob nuclear, cov chaw tshawb fawb, thiab thaum lub sijhawm thauj cov khoom siv hluav taws xob.Hauv kev kho mob, lawv tau ua haujlwm los ntsuas qhov raug hluav taws xob hauv cov txheej txheem kho mob thiab ua kom muaj kev nyab xeeb ntawm cov neeg kho mob thiab cov neeg mob.Cov koom haum saib xyuas ib puag ncig siv cov ntsuas hluav taws xob ntawm tes los ntsuas cov hluav taws xob hauv ib puag ncig, tshwj xeeb hauv cov cheeb tsam cuam tshuam los ntawm kev sib tsoo nuclear lossis cov kab mob sib kis.Tsis tas li ntawd, cov neeg teb xwm txheej ceev cia siab rau cov cuab yeej no los ntsuas cov hluav taws xob muaj kev phom sij thaum muaj xwm txheej xws li muaj xwm txheej, kev puas tsuaj ntuj tsim, lossis kev ua phem ua phem uas cuam tshuam nrog cov khoom siv hluav taws xob.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum lub ntsuas hluav taws xob ntawm tes yog cov cuab yeej tseem ceeb rau kev kuaj xyuas thiab ntsuas hluav taws xob, lawv tsis yog qhov hloov pauv rau kev coj ua kev nyab xeeb hluav taws xob thiab kev tiv thaiv.Cov neeg siv yuav tsum tau txais kev cob qhia txog kev siv cov cuab yeej no kom raug thiab nkag siab txog cov kev txwv ntawm cov khoom siv hluav taws xob hluav taws xob hauv cov hluav taws xob sib txawv.Tsis tas li ntawd, kev ntsuas ntsuas tsis tu ncua thiab kev saib xyuas ntawm cov cuab yeej yog qhov tseem ceeb los xyuas kom meej thiab txhim khu kev ntsuas.
Hauv kev xaus,handheld radiation metersua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev phom sij ntawm hluav taws xob hauv ntau qhov chaw tshaj lij thiab tus kheej.Los ntawm kev siv cov thev naus laus zis tshawb pom thiab cov yam ntxwv zoo rau cov neeg siv, cov cuab yeej nqa tau yooj yim no ua rau tib neeg thiab cov koom haum saib xyuas thiab teb rau cov kev pheej hmoo hluav taws xob zoo.Kev nkag siab txog kev ntsuas hluav taws xob ntawm tes ua haujlwm li cas thiab lawv cov ntawv thov yog qhov tseem ceeb rau kev txhawb nqa hluav taws xob kev nyab xeeb thiab tiv thaiv pej xeem kev noj qab haus huv thiab ib puag ncig.
