Qhov sib txawv tseem ceeb ntawm becquerel thiab sievert yog tias becquerel yog ib chav siv los ntsuas kev ua haujlwm ntawm cov khoom siv hluav taws xob ntau thaum sievert yog ib chav siv los ntsuas kev noj qab haus huv ntawm cov hluav taws xob ionizing.
Becquerel thiab sievert yog cov ntsuas ntsuas. Ob qho no yog SI derived units. SI derived units yog cov ntsuas ntsuas uas tau muab los ntawm xya lub hauv paus uas tau teev tseg los ntawm International System of Units (SI units). Cov xya hauv paus units yog kilogram, vib nas this, kelvin, ampere, mole, candela thiab meter.
Dab tsi yog Becquerel
Becquerel yog SI derived chav tsev uas peb tuaj yeem siv los ntsuas cov haujlwm ntawm cov khoom siv hluav taws xob ntau. Yog li ntawd, nws yog chav tsev ntawm kev ua haujlwm tshwj xeeb. Lub cim rau becquerel yog Bq. Chav tsev no tau muaj npe tom qab tus kws tshawb fawb Henri Becquerel uas tau qhia txog chav tsev. SI lub hauv paus chav tsev uas yog siv rau derivation ntawm becquerel yog vib nas this (s). Ib tug becquerel yog sib npaug rau s-1 (ib ob). Qhov no txhais tau tias ib tug becquerel yog sib npaug rau cov kev ua ntawm ib tug kom muaj nuj nqis ntawm radioactive khoom nyob rau hauv uas ib tug nucleus decays ib ob. Kev sib raug zoo yog raws li nram no:
1 Bq=1 s-1
Daim duab 01: Kev ntsuas hluav taws xob
Thaum muab lub npe SI no los ntawm chav tsev, muaj ob txoj cai uas peb yuav tsum nco ntsoov. Thawj txoj cai yog tias, thaum muab lub cim ntawm chav tsev, tsab ntawv "B" ib txwm yuav tsum yog lub peev vim tias chav tsev no tau muab lub npe ntawm tus neeg nws lub npe. Txoj cai thib ob yog thaum sau lub npe ntawm chav tsev no ua lus Askiv, peb yuav tsum sau tsab ntawv "b" hauv cov ntawv yooj yim yog tias nws tsis yog thaum pib ntawm kab lus. Ntxiv mus, zoo ib yam li lwm chav SI, peb tuaj yeem siv ua ntej nrog becquerel xws li kilobecquerel (kBq), megabecquerel (MBq), thiab lwm yam.
Sievert yog dab tsi?
Sievert yog SI muab los ntawm peb tuaj yeem siv los ntsuas cov tshuaj ionizing hluav taws xob. Lub cim ntawm chav tsev no yog Sv. Nws yog ib qho kev ntsuas ntawm kev noj qab haus huv ntawm cov qib qis ntawm ionizing hluav taws xob ntawm tib neeg lub cev. Chav tsev no yog qhov tseem ceeb hauv kev sim txog dosimetry thiab tiv thaiv hluav taws xob. Chav tsev no tau muaj npe tom qab tus kws tshawb fawb Rolf Maximilian Sievert. SI puag units uas yog siv los muab cov Sievert yog ' meter ' thiab vib nas this. Ntawm no, ib Sievert sib npaug m2s-2
1Sv=1 m2s-2
Thaum muab lub npe SI no los ntawm chav tsev, muaj ob txoj cai uas peb yuav tsum nco ntsoov. Thawj txoj cai yog tias, thaum muab lub cim ntawm chav tsev, tsab ntawv "S" yuav tsum yog lub peev xwm ib txwm muaj vim tias chav tsev no tau muab npe tom qab tus neeg uas nws lub npe siv los muab lub cim. Txoj cai thib ob yog, thaum sau lub npe ntawm chav tsev no ua lus Askiv, peb yuav tsum sau tsab ntawv "s" ua cov ntawv yooj yim yog tias nws tsis yog nyob rau ntawm kab lus pib.
Qhov txawv ntawm Becquerel thiab Sievert yog dab tsi?
Becquerel thiab Sievert yog cov ntsuas ntsuas. Ob qho no yog SI derived units. SI derived units yog cov ntsuas ntsuas uas tau muab los ntawm xya lub hauv paus uas tau teev tseg los ntawm International System of Units (SI units). Qhov sib txawv tseem ceeb ntawm Becquerel thiab Sievert yog tias Becquerel yog ib chav tsev siv los ntsuas cov haujlwm ntawm cov khoom siv hluav taws xob ntau, qhov Sievert yog ib chav siv los ntsuas kev noj qab haus huv ntawm cov hluav taws xob ionizing.
Hauv qab infographic qhia txog qhov sib txawv ntawm Becquerel thiab Sievert.
Summary – Becquerel vs Sievert
Becquerel thiab Sievert yog cov ntsuas ntsuas. Ob qho no yog SI derived units. SI derived units yog cov ntsuas ntsuas uas tau muab los ntawm xya lub hauv paus uas tau teev tseg los ntawm International System of Units (SI units). Qhov sib txawv tseem ceeb ntawm Becquerel thiab Sievert yog tias Becquerel yog ib chav ntsuas kev ua haujlwm ntawm cov khoom siv hluav taws xob ntau, qhov Sievert yog ib chav ntsuas kev noj qab haus huv ntawm cov hluav taws xob ionizing.
