A hluav taws xob hnyav qhov ntsuas yog qhov kwv yees ntawm qhov ua tau zoo ntawm ib chav tsev ntawm qhov muab hluav taws xob txheeb ze rau tus qauv qis-LET. Gy (joule / kg) tuaj yeem siv rau txhua hom hluav taws xob . Gy tsis piav txog cov teebmeem lom ntawm cov hluav taws xob sib txawv.
Tsuas yog li ntawd, cov ntaub so ntswg qhov hnyav yog dab tsi?
Cov cov ntaub so ntswg weighting factor (WT) yog ib qho kev ntsuas txheeb ze ntawm qhov kev pheej hmoo ntawm cov teebmeem stochastic uas yuav tshwm sim los ntawm irradiation ntawm qhov tshwj xeeb ntaub so ntswg . Nws suav rau qhov sib txawv ntawm radiosensitivities ntawm lub cev thiab cov ntaub so ntswg nyob rau hauv lub cev rau ionizing hluav taws xob.
Ib tug kuj yuav nug, dab tsi yog qhov zoo tshaj plaws hauv hluav taws xob? Cov yam zoo ( Q ) yog a yam siv hauv hluav taws xob kev tiv thaiv kom hnyav cov tshuaj absorbed nrog rau nws txoj kev ua haujlwm lom neeg. Hluav taws xob nrog siab dua Q yam yuav ua rau muaj kev puas tsuaj loj rau cov ntaub so ntswg. Lub rem yog ib lo lus siv los piav txog ib chav tshwj xeeb ntawm koob tshuaj sib npaug.
Tom qab ntawd, dab tsi yog qhov hluav taws xob hnyav rau gamma rays?
Hom hluav taws xob thiab hom ntaub so ntswg
| Hluav taws xob | Radiation weighting factor () |
|---|---|
| alpha hais | 20 |
| beta hais | 1 |
| gamma rays | 1 |
| qeeb neutrons | 3 |
Koj xam hluav taws xob li cas?
Thaum ib tug neeg raug hluav taws xob , cov kws tshawb fawb tuaj yeem sib ntxiv cov koob tshuaj hauv rad los ntawm qhov zoo tshaj plaws rau hom hluav taws xob tam sim no thiab kwv yees tus neeg txoj kev pheej hmoo lom neeg hauv rems. Yog li, kev pheej hmoo hauv rem = rad X Q. Lub rem tau hloov los ntawm Sv. Ib Sv yog sib npaug rau 100 rem.

Dab tsi yog qhov density dependent limiting factor txhais li cas?
Ceev Yus Tswj yam Lub ceev nyob yam yog yam tseem ceeb uas nws los nyob rau hauv lub me me los yog txoj kev loj hlob ntawm cov pejxeem sib txawv nrog cov pejxeem ceev. Muaj ntau ntau yam ntawm qhov ntom ntom ntawm qhov txwv tsis pub muaj xws li; muaj zaub mov, predation, kab mob, thiab tsiv teb tsaws
Dab tsi yog ob tus cwj pwm ntawm electromagnetic radiation?
EM hluav taws xob yog li lub npe vim nws muaj hluav taws xob thiab sib nqus teb uas ib txhij oscillate hauv cov dav hlau sib txuas rau ib leeg thiab mus rau kev taw qhia ntawm kev nthuav tawm los ntawm qhov chaw. ✓ Electromagnetic hluav taws xob muaj ob qhov xwm txheej: nws nthuav tawm cov khoom yoj thiab cov khoom siv (photon)
Dab tsi yog txhais los ntawm steric factor?
Kuj hu ua qhov tshwm sim qhov tshwm sim, qhov steric tau txhais tias yog qhov piv ntawm qhov kev sim ntawm tus nqi tas li thiab qhov kwv yees los ntawm kev sib tsoo txoj kev xav. Nws tseem tuaj yeem txhais tau tias yog qhov piv ntawm qhov ua ntej exponential thiab qhov sib tsoo zaus, thiab nws feem ntau tsawg dua kev sib sau
Dab tsi yog ionic packing factor?
Ionic packing factor (IPF), zoo ib yam txhais ntawm APF. Tib txoj cai raws li cov hlau w / hwm rau siv lead ua symmetry. Yuav ua li cas yog ions los ntawm cov qauv siv lead ua? Qauv: CsCl hom Bravais lattice: yooj yim cubic Ions/unit cell: 1 Cs + + 1 Cl ? Cl? Cs + 7 (tsis yog atoms) 1
Lub Cheebtsam ntawm Lub Ntiaj Teb Radiation Budget yog dab tsi?
Lub Ntiaj Teb Radiation Budget. Lub zog nkag mus, xav txog, nqus, thiab tawm los ntawm lub ntiaj teb yog cov khoom siv hluav taws xob hluav taws xob hauv ntiaj teb
