Qhov sib txawv tseem ceeb ntawm kev sib kis ntawm cov xov tooj cua thiab irradiation yog tias cov kab mob sib kis tau tshwm sim thaum muaj kev sib cuag ncaj qha nrog cov khoom siv hluav taws xob, qhov irradiation tshwm sim thaum muaj kev cuam tshuam ncaj qha rau cov khoom siv hluav taws xob.

Radioactivity yog cov txheej txheem uas cov khoom tawm los ntawm cov nuclei vim yog kev tsis sib haum xeeb ntawm cov khoom siv. Cov ntaub ntawv no muaj npe ua cov khoom siv hluav taws xob. Radioactive contamination thiab irradiation yog ob lub ntsiab lus tseem ceeb ntsig txog kev siv hluav taws xob hauv lub cev chemistry.

Dab tsi yog Radioactive Contamination?

Radioactive contamination yog qhov tso tawm los yog muaj cov khoom siv hluav taws xob nyob rau ntawm qhov chaw uas lawv tsis xav tau. Qhov no tseem hu ua radiological contamination. Qhov kev tso tawm ntawm cov khoom siv hluav taws xob tuaj yeem tshwm sim rau ntawm qhov chaw xws li cov khib nyiab, kua lossis txawm tias gases (xws li muaj cov khoom siv hluav taws xob hauv cov pa roj). Qhov tseem ceeb tshaj plaws, peb tuaj yeem txheeb xyuas cov khoom siv hluav taws xob muaj nyob rau thaum nws tsis xav tau. Cov ntsiab lus tshwj xeeb no tau muab los ntawm International Atomic Energy Agency lossis IAEA.

Daim duab 01: Nuclear Disaster hauv Fukushima

Thaum muaj cov kab mob sib kis, nws yog qhov phom sij vim tias cov khoom siv hluav taws xob no tuaj yeem ua rau cov hluav taws xob tawg, ua rau muaj kev phom sij xws li hluav taws xob ionizing (xws li alpha rays, beta rays thiab gamma rays) thiab dawb neutrons tso tawm. Qib ntawm kev phom sij tuaj yeem txiav txim siab los ntawm qhov concentration ntawm cov khoom paug, lub zog ntawm cov hluav taws xob emitting, hom hluav taws xob tawm, qhov sib thooj ntawm cov kab mob ntawm peb lub cev, thiab lwm yam.

Muaj ob txoj hauv kev loj ntawm kev sib kis ntawm cov xov tooj cua: natural thiab manmade radioactive pollution. Cov txheej txheem muaj kuab paug muaj xws li cov khoom siv hluav taws xob uas tshwm sim thoob plaws qhov xwm txheej (hauv av, dej, nroj tsuag) thiab cov kab mob uas tuaj yeem tshwm sim los ntawm kev noj los yog nqus tau. Cov neeg tsim muaj kuab paug tuaj yeem tshwm sim tom qab lub ntiaj teb muaj riam phom nuclear tawm, nuclear reactor muaj kev ua txhaum cai, nuclear roj, thiab fission khoom tso tawm.

Irradiation yog dab tsi?

Irradiation yog txheej txheem uas ib yam khoom raug hluav taws xob. Qhov kev raug hluav taws xob no tuaj yeem tshwm sim los ntawm ntau qhov chaw, suav nrog qhov chaw ntuj. Txawm li cas los xij, lub sij hawm irradiation tsis suav nrog cov hluav taws xob tsis yog ionizing, suav nrog IR hluav taws xob, pom lub teeb, microwaves, thiab lwm yam.

Muaj ntau yam kev siv irradiation xws li kev ua kom tsis muaj menyuam, kev siv tshuaj kho mob nrog rau kev kuaj pom, kev kho mob qog noj ntshav, thiab lwm yam., ion implantation, ion irradiation, daim ntawv thov hauv kev lag luam chemistry rau crosslinking ntawm cov ntaub ntawv yas, kev siv hauv kev ua liaj ua teb los tiv thaiv cov qoob loo. los ntawm kab, thiab lwm yam.

Dab tsi zoo sib xws ntawm Radioactive Contamination thiab Irradiation?

  • Ob nqe lus, kev kis kab mob hauv xov tooj cua thiab irradiation, yog siv rau hauv lub cev chemistry.
  • Ob nqe lus piav qhia lub tswvyim ntawm hluav taws xob.

Qhov txawv ntawm Radioactive Contamination thiab Irradiation yog dab tsi?

Radioactive contamination yog qhov tso tawm los yog muaj cov khoom siv hluav taws xob nyob rau ntawm qhov chaw uas lawv tsis xav tau. Irradiation yog txheej txheem uas ib yam khoom raug hluav taws xob. Qhov sib txawv tseem ceeb ntawm cov kab mob sib kis thiab irradiation yog tias cov kab mob sib kis tau tshwm sim thaum muaj kev sib cuag ncaj qha nrog cov khoom siv hluav taws xob, qhov irradiation tshwm sim thaum muaj kev cuam tshuam ncaj qha rau cov khoom siv hluav taws xob.

Cov lus hauv qab no qhia txog qhov sib txawv ntawm cov kab mob sib kis thiab irradiation.

Summary – Radioactive Contamination vs Irradiation

Xov tooj cua sib kis thiab irradiation yog ob lub ntsiab lus tseem ceeb ntsig txog xov tooj cua hauv lub cev chemistry. Qhov sib txawv tseem ceeb ntawm cov kab mob sib kis thiab irradiation yog tias cov kab mob sib kis tau tshwm sim thaum muaj kev sib cuag ncaj qha nrog cov khoom siv hluav taws xob, qhov irradiation tshwm sim thaum muaj kev cuam tshuam ncaj qha rau cov khoom siv hluav taws xob.
