Tsis-ionizing tawg. Hom thiab cov yam ntxwv ntawm hluav taws xob

Txhua qhov txhia chaw peb yog surrounded los ntawm electromagnetic teb. Nyob ntawm seb nws wavelength ntau, tej zaum lawv yuav ua txawv nyob rau hauv uas muaj sia nyob. Kev zam txim rau xam tau tias yog uas tsis yog-ionizing tawg, txawm li cas los, thiab tej zaum lawv tsis muaj kev nyab xeeb. Yuav ua li cas yog no tshwm sim, thiab ua li cas tej yam lawv muaj nyob rau hauv peb lub cev?

Yuav ua li cas yog tsis yog-ionizing tawg?

Lub zog yog faib nyob rau hauv daim ntawv ntawm cov zoo hais thiab tsis. Ua nws emission thiab hais tawm ntawm hluav taws xob hu ua. Los ntawm qhov xwm ntawm tej yam rau cov khoom thiab kev ua neej ntaub so ntswg yog ob lub ntsiab hom ntawm nws. Thawj - ionizing nruab nrab yog cov kwj ntawm cov elementary hais uas yog tsim los ntawm cov paub faib atoms. Nws comprises ib tug neeg, alpha, beta, gamma, X-ray, tawg thiab gravitational Hawking rays.

Qhov thib ob hom ntawm hluav taws xob yog non-ionizing tawg. Nyob rau hauv qhov tseeb, qhov no electromagnetic yoj, qhov ntev uas yog muaj ntau dua 1000 nm, thiab tus nqi ntawm tso zog tsawg tshaj li 10 Txoj Kev Hlub. Nws ua raws li microwaves, uas ua rau tso cua sov thiab lub teeb.

Nyob rau hauv sib piv rau lub thawj hom, qhov no tawg tsis ionize atoms thiab molecules ntawm qhov teeb meem, nyob rau hauv uas ua, i.e. tsis tawg kev sib txuas lus nruab nrab ntawm nws molecules. Ntawm cov hoob kawm, muaj ib co kev zam. Yog li, nyob rau hauv tej yam hom, piv txwv li, UV rays yuav ionize teeb meem.

Hom ntawm Non-Ionizing Tawg

Electromagnetic tawg yog ib tug ntau dav heev tswvyim tshaj qhov uas tsis yog-ionizing. High-zaus X-ray thiab gamma-rays kuj electromagnetic, tab sis lawv muaj ntau yeem thiab ionize qhov teeb meem. Tag nrho lwm cov ntaub ntawv ntawm cov electromagnetic tawg yog non-ionizing, lawv lub zog yog tsis txaus los cuam tshuam nyob rau hauv tus qauv ntawm cov teeb meem.

Qhov loj tshaj ntev ntawm lawv muaj xov tooj cua yoj, uas nws ntau mas nws txawv ntawm super-ntev (10 km) mus rau lub VHF (10 m - 1 hli). EM tsis lwm tawg yog tsawg tshaj li 1 hli. Tom qab lub xov tooj cua yog infrared los yog thaum tshav kub kub, qhov ntev ntawm nws tsis yog nyob ntawm cov cua kub kub.

Tsis-ionizing kuj pom lub teeb thiab ultraviolet tawg. Thawj feem yog hu ua kho qhov muag. Nws spectrum yog heev ze rau infrared rays thiab yog tsim los ntawm cov cua kub cev. Ultraviolet tawg yog nyob ze rau lub X-ray, li ntawd, tej zaum nws yuav muaj peev xwm sawv ntawm ionization. Nyob rau ib lub wavelength ntawm 400 rau 315 nm, nws paub ib tug tib neeg lub qhov muag.

qhov chaw

Tsis-ionizing electromagnetic tawg tej zaum yuav ob yam thiab dag keeb kwm. Ib tug ntawm lub ntsiab yam ntuj tso qhov chaw yog lub hnub. Nws xa tag nrho cov hom ntawm hluav taws xob. Tag nrho cov allergic ntawm peb ntiaj chaw lub ntiaj teb huab cua tes. Vim lub ozone layer, ya raws, carbon dioxide siab phem txiav txim rays heev mitigated.

Rau xov tooj cua tsis tau ua raws li ib tug natural qhov chaw ntawm xob laim, raws li zoo raws li qhov chaw tej khoom. Thermal infrared rays yuav emit tej rhuab mus rau lub yam kub cev, txawm hais tias lub ntsiab tawg los ntawm ib tug txiv neej-ua khoom. Yog li, nws cov ntsiab qhov chaw yog cua sov, burners thiab zoo tib yam qhov muag teeb uas tam sim no nyob rau hauv txhua txhua lub tsev.

Xov tooj cua tsis yog kis tau nyob rau hauv tej hluav taws xob conductors. Yog li ntawd, lub dag yog tag nrho cov hluav taws xob khoom siv, raws li tau zoo raws li pab kiag li lawm rau wireless kev sib txuas lus, xws li cov xov tooj txawb, satellites thiab thiaj li nyob. D. ultraviolet rays yog kev kawm mus rau ib tug tshwj xeeb fluorescent, mercury-quartz teeb, LEDs, excilamp.

Impact on tib neeg

Lub electromagnetic tawg yog yus muaj los ntawm wavelength, zaus, thiab polarization. Los ntawm tag nrho ntawm cov kev thiab nws nyob rau lub zog ntawm nws feem. Tshaj lub wavelength, lub tsawg zog nws hloov rau tus kwv, thiab yog li ntawd, yog tsawg teeb meem. Qhov tseem nyhuv dejnum ntawm hluav taws xob nyob rau hauv lub decimetre-centimeter ntau yam.

Tsis-ionizing tawg nyob rau hauv lub sij hawm ntev los ntawm ib tug neeg muaj peev xwm ua rau mob, txawm hais tias lawv tej zaum yuav pab tau nyob rau hauv moderation. Ultraviolet rays yuav ua rau daim tawv nqaij Burns thiab qhov muag cornea, ua ib tug ntau yam ntawm change. Ib tug tshuaj rau lawv yog tsim nyob rau hauv daim tawv nqaij vitamin D3, sterilized khoom decontaminated dej thiab huab cua.

Nyob rau hauv cov tshuaj, lub infrared tawg yog siv los txhim kho lub metabolism thiab kov kev, tua ntawm cov khoom noj. Yog hais tias ntev li thaum tshav kub kub yog cov tawg muaj peev xwm ntawm xav sear txheej qhov muag, thiab rau siab kawg hwj chim - txawm ua kom puas lub DNA molecule.

Xov tooj cua tsis siv rau mobile thiab xov tooj cua kev sib txuas lus, navigation systems, TV, thiab lwm yam hom phiaj. Passive xov tooj cua zaus emanating los ntawm khoom vaj khoom tsev, yuav ua rau kom lub excitability ntawm poob siab system, tsis tau lub hlwb muaj nuj nqi, muaj ib tug tsis zoo feem nyob rau hlab plawv system thiab fertility.
