Isishwankathelo

Yintoni imitha?

Imitha ngamandla. Ihamba ngokohlobo lwamandla amaza okanye amasuntswana akhawulezayo. Imitha inokwenzeka ngokwendalo okanye yenziwe ngumntu. Zimbini iintlobo:

• Imitha engasebenziyo, Okubandakanya amaza erediyo, iiselfowuni, ii-microwaves, i-infrared radiation kunye nokukhanya okubonakalayo
• Imitha ebangayo, Okubandakanya imitha ye-ultraviolet, i-radon, i-x-reyi, kunye nemitha ye-gamma

Yeyiphi imithombo yokuvezwa kwemitha?

Imitha yangasemva ijikeleze lonke ixesha. Uninzi lwayo lwenzeka ngokwendalo kwizimbiwa. Ezi zimbiwa ziradioactive zisemhlabeni, emhlabeni, emanzini, nakwimizimba yethu. Imitha yangemuva nayo inokuvela kwindawo engaphandle kunye nelanga. Eminye imithombo yenziwe ngumntu, njenge-x-reyi, unyango ngemitha ukunyanga umhlaza, kunye neentambo zombane.

Zithini iimpembelelo zokuvezwa yimitha?

Imitha ibijikeleze thina kwindalo yethu yonke. Ke imizimba yethu yenzelwe ukujongana namanqanaba asezantsi esiye sichanabeke kuwo yonke imihla. Kodwa imitha eninzi kakhulu inokonakalisa izicwili ngokutshintsha ubume beseli kunye nokonakalisa iDNA. Oku kunokubangela iingxaki zempilo, kubandakanya umhlaza.

Ubungakanani bomonakalo onokubangelwa kukuvezwa yimitha kuxhomekeke kwizinto ezininzi, kubandakanya

• Uhlobo lwemitha
• Idosi (isixa) semitha
• Uvezwe njani, njengokunxibelelana nolusu, ukuginya okanye ukuphefumla ngaphakathi, okanye ukuba nemitha idlula emzimbeni wakho
• Apho imitha igxila emzimbeni kwaye ihlala ixesha elingakanani apho
• Ubuthathaka kangakanani emzimbeni wakho kwimitha. Usana olungekazalwa lusesichengeni seziphumo zemitha. Iintsana, abantwana, abantu abadala abadala, abafazi abakhulelweyo, kunye nabantu abanamajoni omzimba abuthathaka basesichengeni seziphumo zempilo kunabantu abadala abasempilweni.

Ukuvezwa kwimitha emininzi ngexesha elifutshane, njengakwimeko engxamisekileyo yemitha, kunokubangela ukutsha kolusu. Inokukhokelela kwisifo se-radiation esibuhlungu (i-ARS, okanye "ukugula kwemitha"). Iimpawu ze-ARS zibandakanya intloko ebuhlungu kunye norhudo. Zihlala ziqala kwiyure nje ezimbalwa. Ezo mpawu ziya kumka kwaye umntu abonakale esempilweni ithutyana. Kodwa baya kuphinda bagule kwakhona. Bakhawuleza bagule kwakhona, zimpawu banazo, kwaye bagule kangakanani kuxhomekeke kubungakanani bemitha abayifumeneyo. Ngamanye amaxesha, ii-ARS zibangela ukufa kwezi ntsuku okanye iiveki ezilandelayo.

Ukubonakaliswa kumanqanaba asezantsi emitha kwindalo esingqongileyo akubangeli ziphumo zempilo kwangoko. Kodwa inokunyusa kancinci umngcipheko wakho womhlaza.

Luthini unyango lokugula kakhulu kwemitha?

Ngaphambi kokuba baqalise unyango, iingcali zokhathalelo lwempilo kufuneka babone ukuba ingakanani imitha emzimbeni wakho efungelweyo. Baza kubuza malunga neempawu zakho, benze uvavanyo lwegazi, kwaye banokusebenzisa isixhobo esilinganisa imitha. Bazama kwakhona ukufumana ulwazi oluthe kratya malunga nokuvezwa, njengohlobo lwe-radiation, yayikude kangakanani ukusuka kumthombo we-radiation, kunye nokuba wavezwa ixesha elingakanani.

Unyango lujolise ekunciphiseni nasekunyangeni izifo, ukuthintela ukomisa, nokuphatha ukonzakala kunye nokutsha. Abanye abantu banokufuna unyango olunceda umongo wethambo ukuba uphinde usebenze. Ukuba ubuchanekile kwiintlobo ezithile zemitha, umboneleli wakho unokukunika unyango olunciphisa okanye lususe ukungcola okungaphakathi emzimbeni wakho. Unokufumana unyango kwiimpawu zakho.

Ukuthintelwa kwemitha kunokuthintelwa njani?

Kukho amanyathelo onokuwathatha ukuthintela okanye ukunciphisa ukubonakaliswa kwemitha:

• Ukuba umboneleli wakho wezempilo ucebisa uvavanyo olusebenzisa imitha, buza malunga neengozi kunye nezibonelelo. Ngamanye amaxesha, unokukwazi ukuba novavanyo olwahlukileyo olungasebenzisi radiation. Kodwa ukuba ufuna uvavanyo olusebenzisa imitha, yenza uphando kumaziko okucinga asekhaya. Fumana enye ebeka iliso kwaye isebenzise iindlela ukunciphisa iidosi abazinika abaguli.
• Ukunciphisa ukubonakaliswa kwemitha ye-electromagnetic kwifowuni yakho. Okwangoku, ubungqina besayensi abukafumani unxibelelwano phakathi kokusebenzisa iselfowuni kunye neengxaki zempilo ebantwini. Uphando olungakumbi luyafuneka ukuqinisekisa. Kodwa ukuba usenenkxalabo, unokunciphisa ixesha olichitha kwifowuni yakho. Ungasebenzisa imowudi yesithethi okanye iseti yentloko ukubeka umgama phakathi kwentloko kunye neselfowuni.
• Ukuba uhlala endlwini, vavanya amanqanaba eradon, kwaye ukuba ufuna njalo, fumana inkqubo yokunciphisa i-radon.
• Ngexesha likaxakeka ngemitha, ngena ngaphakathi kwisakhiwo ukuze uzikhusele. Hlala ngaphakathi, zonke iifestile neengcango zivaliwe. Hlala ubukele kwaye ulandele iingcebiso zabaphenduli abangxamisekileyo kunye namagosa.
