Litaba

Re kenyelletsa lihlahisoa tseo re nahanang hore li na le thuso ho babali ba rona. Haeba u reka ka lihokela tse leqepheng lena, re ka fumana khomishene e nyane. Ts'ebetso ea rona ke ena.

Kakaretso

Boholo ba rona re tloaetse menyetla ea bophelo ba sejoale-joale. Empa ke ba fokolang ba rona ba tsebang likotsi tse ka bang teng tsa bophelo bo botle tse hlahisoang ke lisebelisoa tse etsang hore lefatše la rona le sebetse.

Hoa etsahala hore liselefounu tsa rona, li-microwave, li-routers tsa Wi-Fi, likhomphutha le lisebelisoa tse ling li romella leqhubu la maqhubu a sa bonahaleng a matla ao litsebi tse ling li amehileng ka ona. Na re lokela ho tšoenyeha?

Ho tloha tšimolohong ea bokahohle, letsatsi le rometse maqhubu a etsang motlakase le matla a khoheli (EMFs), kapa radiation. Ka nako e ts'oanang letsatsi le romella li-EMF, re khona ho bona matla a lona a tsoa. Sena ke kganya e bonahalang.

Mathoasong a lekholo la bo20 la lilemo, lithapo tsa motlakase le mabone a ka tlung li ile tsa namela lefatšeng ka bophara. Bo-rasaense ba ile ba hlokomela hore likhoele tsa motlakase tse fepelang batho bohle lefatšeng ka matla ao kaofela li ne li romella li-EMF, joalo ka ha letsatsi le etsa ka tlhaho.


Ho theosa le lilemo, bo-rasaense ba boetse ba ithutile hore lisebelisoa tse ngata tse sebelisang motlakase le tsona li theha li-EMF joalo ka likhoele tsa motlakase. X-rays, le mekhoa e meng ea ho nka litšoantšo tsa bongaka e kang MRIs, le eona e fumanoe e etsa li-EMF.

Ho latela Banka ea Lefatše, liperesente tse 87 tsa baahi ba lefats'e ba na le motlakase ebile ba sebelisa lisebelisoa tsa motlakase kajeno. Ke motlakase o mongata le li-EMF tse entsoeng lefats'eng ka bophara. Esita le ka maqhubu ao kaofela, bo-rasaense ka kakaretso ha ba nahane hore li-EMF ke mathata a bophelo bo botle.

Empa le hoja ba bangata ba sa lumele hore li-EMF li kotsi, ho ntse ho na le bo-rasaense ba bang ba belaelang ho pepeseha. Ba bangata ba re ha ho so be le lipatlisiso tse lekaneng ho utloisisa hore na li-EMF li bolokehile. A re ke re hlahlobisiseng.

Mefuta ea tlhahiso ea EMF

Hona le mefuta e 'meli ea tlhahiso ea EMF. Mahlaseli a boemo bo tlase, ao hape a bitsoang mahlaseli a seng a ioni, a bonolo ebile ho nahanoa hore a se kotsi ho batho. Lisebelisoa tse kang lioli tsa microwave, liselefouno, li-routers tsa Wi-Fi, hammoho le lithapo tsa motlakase le li-MRIs, li romela mahlaseli a boemo bo tlase.


Mahlaseli a boemo bo phahameng, a bitsoang radiation ea ionizing, ke mofuta oa bobeli oa radiation. E romeloa ka mokhoa oa mahlaseli a ultraviolet a tsoang letsatsing le X-ray e tsoang mechineng ea litšoantšo tsa bongaka.

Matla a ho pepeseha ha EMF a fokotseha ha o ntse o eketsa hole le ntho e romelang maqhubu. Mehloli e meng e tloaelehileng ea li-EMF, ho tloha mahlaseling a tlase ho isa boemong bo phahameng, e kenyelletsa tse latelang:

Mahlaseli a sa boneng

  • ontong microwave
  • likhomphutha
  • limithara tse matla a ntlo
  • li-routers tse se nang mohala (Wi-Fi)
  • diselefounu
  • Lisebelisoa tsa Bluetooth
  • lithapo tsa motlakase
  • MRIs

Mahlaseli a kotsi

  • khanya ea mahlaseli
  • Li-X-ray

Lipatlisiso ka kotsi

Ho na le ho se lumellane ka polokeho ea EMF hobane ha ho na lipatlisiso tse matla tse fanang ka maikutlo a hore EMF e senya bophelo ba batho.

Ho ea ka Mokhatlo oa Lefatše oa Bophelo oa Lipatlisiso ka Kankere (IARC), li-EMF "mohlomong li baka kankere ho batho." IARC e lumela hore lithuto tse ling li bonts'a khokahano e ka bang teng lipakeng tsa EMF le mofetše bathong.


Ntho e le 'ngoe eo batho ba bangata ba e sebelisang letsatsi le letsatsi e romellang li-EMF ke selefounu. Ts'ebeliso ea liselefounu e eketsehile haholo ho tloha ha li ne li hlahisoa lilemong tsa bo-1980. Ba amehile ka bophelo ba batho le ts'ebeliso ea selefounu, bafuputsi ba ile ba qala se neng se tla bapisa linyeoe tsa mofets'e ho basebelisi ba mehala ea selefounu le bao e seng basebelisi morao ho 2000.

Bafuputsi ba ile ba latela litefiso tsa mofetše le ts'ebeliso ea mehala ea cellular ho batho ba fetang 5,000 linaheng tse 13 ho pota lefatše. Ba fumane khokahano e hlephileng lipakeng tsa sekhahla se phahameng sa ho pepeseha le glioma, mofuta oa mofetše o hlahang bokong le mokokotlong.

Li-gliomas li ne li fumaneha hangata lehlakoreng le leng la hlooho leo batho ba neng ba tloaetse ho bua ka lona fonong. Leha ho le joalo, bafuputsi ba fihletse qeto ea hore ha ho na kamano e matla e lekaneng ho tseba hore ts'ebeliso ea selefounu e bakile mofetše lihloohong tsa lipatlisiso.

Phuputsong e nyane empa e sa tsoa etsoa, ​​bafuputsi ba fumane hore batho ba pepeselitsoeng maemo a phahameng a EMF ka lilemo tse ngata ba bontšitse kotsi e eketsehileng ea mofuta o itseng oa kankere ea mali ho batho ba baholo.

Bo-rasaense ba Europe le bona ba ile ba sibolla kamano e bonahalang lipakeng tsa EMF le kankere ea mali ho bana. Empa ba re ho lekola EMF hoa haella, ka hona ha ba khone ho fihlela liqeto tse itseng mosebetsing oa bona, mme ho hlokahala lipatlisiso le tlhaiso-leseling e batsi.

Tlhahlobo ea lithuto tse fetang leshome le metso e 'meli ho li-EMF tse maqhubu a tlase e fana ka maikutlo a hore masimo ana a matla a ka baka mathata a fapaneng a methapo le mafu a kelello bathong. Sena se fumane khokahano lipakeng tsa ho pepeseha ha EMF le liphetoho ts'ebetsong ea methapo ea motho 'meleng oohle, e amang lintho tse kang ho robala le maikutlo.

Maemo a kotsi

Mokhatlo o bitsoang Khomishene ea Machabeng ea Ts'ireletso ea Mahlaseli a sa Etseng Ionizing (ICNIRP) e boloka tataiso ea machabeng bakeng sa tlhahiso ea EMF. Tsamaiso ena e ipapisitse le se fumanoeng ke lipatlisiso tsa mahlale tsa lilemo tse ngata.

Li-EMF li lekantsoe ka yuniti e bitsoang volts ka mitha (V / m). Ha tekanyo e phahame, EMF e matla le ho feta.

Lisebelisoa tse ngata tsa motlakase tse rekisoang ke lihlahisoa tse tsebahalang li leka lihlahisoa tsa tsona ho netefatsa hore li-EMF li oela melaong ea ICNIRP. Lits'ebeletso tsa sechaba le mebuso li ikarabella ho laola li-EMF tse amanang le likhoele tsa motlakase, litora tsa selefounu le mehloli e meng ea EMF.

Ha ho litla-morao tse tsebahalang tsa bophelo bo botle tse lebelletsoeng haeba ho pepeseha ha hau ho EMF ho oela ka tlase ho maemo a tataisong e latelang:

  • masimo a motlakase oa tlhaho (joalo ka a entsoeng ke letsatsi): 200 V / m
  • motlakase (eseng haufi le lithapo tsa motlakase): 100 V / m
  • motlakase (haufi le lithapo tsa motlakase): 10,000 V / m
  • literene tsa motlakase le literempe: 300 V / m
  • Litšoantšo tsa TV le likhomphutha: 10 V / m
  • Lisebelisoa tsa TV le seea-le-moea: 6 V / m
  • liteishene tsa mehala ea mehala ea thekeng: 6 V / m
  • Lisebelisoa: 9 V / m
  • liofshoa tsa microwave: 14 V / m

U ka sheba li-EMF ka tlung ea hau ka mitha ea EMF. Lisebelisoa tsena tse tšoaroang ka letsoho li ka rekoa inthaneteng. Empa hlokomela hore ba bangata ha ba khone ho metha li-EMF tsa maqhubu a phahameng haholo 'me ho nepahala ha tsona ka kakaretso ho tlase, ka hona ts'ebetso ea tsona e na le moeli.

Lisebelisoa tsa EMF tse rekisoang haholo ho Amazon.com li kenyelletsa lisebelisoa tse tšoaroang ka letsoho tse bitsoang gaussmeters, tse entsoeng ke Meterk le TriField. U ka letsetsa k'hamphani ea heno ea matla ho hlophisa ho bala sebakeng sa marang-rang.

Ho latela ICNIRP, ho pepesehela batho ba bangata ho EMF ho tlase haholo bophelong ba letsatsi le letsatsi.

Matšoao a ho pepeseha ha EMF

Ho ea ka bo-rasaense ba bang, li-EMF li ka ama tšebetso ea methapo ea mmele oa hau mme tsa baka tšenyo liseleng. Kankere le kholo e sa tloaelehang e kanna ea ba sesupo se le seng sa ho pepeseha ha EMF haholo. Matšoao a mang a kenyeletsa:

  • litšitiso tsa boroko, ho kenyelletsa le ho hlobaela
  • hlooho e opang
  • khatello ea maikutlo le matšoao a tepeletsang
  • mokgathala le mokgathala
  • dysesthesia (bohloko bo bohloko, hangata bo utloisang bohloko)
  • ho hloka mohopolo
  • liphetoho mohopolong

  • ho nyekeloa ke pelo
  • ho chesa letlalo le ho hlohlona
  • liphetoho ho electroencephalogram (e lekanyang ts'ebetso ea motlakase bokong)

Matšoao a ho pepeseha ha EMF ha a hlaka ebile ho bonahala eka matšoao a teng ha a bonahale. Ha re e-s'o tsebe ho lekaneng ka litlamorao ho bophelo ba motho. Patlisiso lilemong tse tlang e kanna ea re tsebisa betere.

Ts'ireletso ho tlhahiso ea EMF

Ho ea ka lipatlisiso tsa morao-rao, li-EMF ha li na monyetla oa ho baka litlamorao tse mpe tsa bophelo bo botle. U lokela ho ikutloa u sireletsehile ha u sebelisa selefounu ea hau, le lisebelisoa tsa ka tlung. U lokela hape ho ikutloa u bolokehile haeba u lula haufi le lithapo tsa motlakase, kaha maqhubu a EMF a le tlase haholo.

Ho fokotsa ho pepeseha hoa maemo a holimo le likotsi tse amanang le tsona, amohela feela li-X-ray tse hlokahalang moeeng le ho fokotsa nako ea hau u le letsatsing.

Sebakeng sa ho tšoenyeha ka li-EMF, o lokela ho li tseba feela le ho fokotsa ho pepeseha. Beha fono ea hau fatše ha u sa e sebelise. Sebelisa sebui sa sebui kapa li-earbuds kahoo ha ho hlokahale hore e be ka tsebe ea hau.

Tlohela fono ea hau ka kamoreng e 'ngoe ha u robetse. Se ke oa nka mohala oa hau ka pokothong kapa ka bra ea hau. Hlokomela mekhoa e ka bang teng ea ho pepesoa le ho ntša lisebelisoa tsa elektroniki le motlakase ebe o ea kampong hang ka nakoana.

Ela hloko litaba bakeng sa lipatlisiso tse ntseng li nts'etsapele mabapi le litlamorao tsa bophelo bo botle.

Ntlha ea bohlokoa

Li-EMF li hlaha ka tlhaho hape li tsoa mehloling e entsoeng ke batho. Bo-rasaense ba fumane likamano tse fokolang tse ka bang teng lipakeng tsa maemo a tlase a EMF le mathata a bophelo bo botle, joalo ka mofets'e.

Ho pepesetsoa maemo a phahameng a EMF ho tsejoa ho baka mathata a methapo le a mmele ka ho senya ts'ebetso ea methapo ea motho. Empa ha ho bonahale eka o tla pepesetsoa li-EMF tsa maqhubu a phahameng bophelong ba hau ba letsatsi le letsatsi.

Hlokomela hore li-EMF li teng. Mme o hlalefe ka ho pepeseha ka maemo a hodimo ka X-ray le letsatsi. Le ha ena e le lefapha le ntseng le tsoela pele la lipatlisiso, ha ho bonahale eka ho pepeseha ha maemo a tlase ho li-EMF ho kotsi.
