Qee qhov cim ntawm pob khoom siv hluav taws xob muaj xws li hauv qab no:
- Lub Npe Shipping Zoo, Hom Pob, thiab UN tus lej cim (piv txwv li, Cov khoom siv hluav taws xob , Hom A pob, UN 2915)
- “ Xov tooj cua LSA” (cov haujlwm tshwj xeeb tsawg) lossis “ Xov tooj cua SCO”1 (cov khoom uas muaj kab mob saum npoo av) (yog muaj)
Ib yam li ntawd, koj ua li cas rau cov khoom siv hluav taws xob?
Cov txheej txheem siv tau
- hnav lub tsho lab. Yog tias muaj kev pheej hmoo ntawm kev kis kab mob hnyav, hnav khaub ncaws pov tseg.
- ib txwm hnav hnab looj tes thaum tuav cov khoom siv hluav taws xob.
- hnav khau npog hauv cov chav uas hauv pem teb yuav kis tau.
- khaws cov khoom ntiag tug xws li hnab tes, thiab lwm yam, sab nraum chav kuaj.
Ib tug kuj tseem nug, daim ntawv lo twg yog siv rau cov pob khoom uas muaj cov hluav taws xob tsawg? Radioactive Dawb-I daim ntawv lo yog txuas rau pob khoom nrog heev qib qis ntawm sab nraud hluav taws xob . Qhov siab tshaj plaws kev sib cuag hluav taws xob theem txuam nrog qhov no daim ntawv lo yog 0.5 mrem/h.
Yog li ntawd, hom A xov tooj cua yog dab tsi?
Hom A.' Hom A' pob khoom siv rau kev thauj khoom me me, tab sis tseem ceeb, ntau ntawm cov khoom siv hluav taws xob . Lawv tau tsim los tiv thaiv kev raug xwm txheej thiab siv rau qhov tsawg kawg nkaus ntawm kev ua haujlwm nruab nrab cov ntaub ntawv , xws li kev kho mob lossis kev lag luam radioisotopes nrog rau qee cov roj nuclear cov ntaub ntawv.
Cov ntawv xov tooj cua twg yog rau cov pob khoom uas muaj hluav taws xob ntau?
RADIOACTIVE WHITE-Kuv yog qeb qis tshaj thiab RADIOACTIVE YELLOW-III yog lub siab tshaj . Piv txwv li, a pob nrog rau kev thauj mus los ntawm 0.8 thiab qhov siab tshaj plaws hluav taws xob theem ntawm 0.6 millisievert (60 millirems) ib teev twg yuav tsum dais a RADIOACTIVE YEEJ-III daim ntawv lo.

Txoj cai lij choj ntawm kev txuag hluav taws xob siv li cas rau kev hloov hluav taws xob?
Txoj cai lij choj ntawm kev txuag hluav taws xob hais tias lub zog tsis tuaj yeem tsim lossis rhuav tshem - tsuas yog hloov los ntawm ib hom ntawm lub zog mus rau lwm qhov. Qhov no txhais tau hais tias ib qho system ib txwm muaj tib lub zog, tshwj tsis yog nws ntxiv los ntawm sab nraud. Tib txoj kev siv lub zog yog hloov lub zog ntawm ib daim ntawv mus rau lwm qhov
Lub teeb ntsuas hluav taws xob siv los kuaj xyuas hluav taws xob li cas?
Lub teeb ntsuas hluav taws xob siv lub teeb tuav hauv ib qho kev sojntsuam txuas nrog tus pas nrig taw tes nrog cov hlau txuas txuas. Qhov kev tsim no yog qhov zoo tshaj plaws rau kev tho cov hlau, kuaj lub fuse lossis kuaj xyuas qhov nqi ntawm lub roj teeb. Yog tias muaj hluav taws xob tam sim no, lub teeb yuav teeb pom tseeb tias lub voj voog muaj zog thiab ua haujlwm zoo
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Cov cuab yeej hluav taws xob siv hluav taws xob ntau npaum li cas?
Tsis tas li ntawd, nco ntsoov txhua yam cuab yeej uas tuaj yeem xaim los khiav ntawm 240 volts es tsis yog tus qauv 120. Tus qauv amperage rau cov cuab yeej hluav taws xob me (sander, jigsaw, thiab lwm yam) yog 2 txog 8 amps. Rau cov cuab yeej hluav taws xob loj (router, ncig pom, tablesaw, tshuab dhos thiab lwm yam), 6 txog 16 amps yog qhov raug
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
