-Delile

Sifaka imikhiqizo esicabanga ukuthi ilusizo kubafundi bethu. Uma uthenga ngezixhumanisi ezikuleli khasi, singathola ikhomishini encane. Nansi inqubo yethu.

Ukubuka konke

Iningi lethu lisetshenziselwe izinto ezilula zanamuhla. Kepha bambalwa kithi abazi ngobungozi bezempilo obungenzeka obuvezwa amagajethi enza umhlaba wethu usebenze.

Kuvela ukuthi omakhalekhukhwini bethu, ama-microwaves, imizila ye-Wi-Fi, amakhompyutha, nezinye izinto ezithunyelwayo zithumela umfudlana wamaza kagesi angabonakali abanye ochwepheshe abakhathazekile ngawo. Ingabe kufanele sikhathazeke?

Kusukela ekuqaleni komkhathi, ilanga lithumele amagagasi akha amandla kagesi namandla kazibuthe (ama-EMF), noma imisebe. Ngasikhathi sinye ilanga lithumela ama-EMF, singabona amandla alo ephuma. Lokhu ukukhanya okubonakalayo.

Ekupheleni kwekhulu lama-20, izintambo zamandla kagesi nokukhanya kwangaphakathi kwasabalala emhlabeni wonke. Ososayensi babona ukuthi izintambo zikagesi ezinikezela wonke lawo mandla kubantu bomhlaba zazithumela ama-EMF, njengoba nje ilanga lenza ngokwemvelo.


Eminyakeni edlule, ososayensi baphinde bafunda ukuthi izinto eziningi ezisebenzisa ugesi nazo zakha ama-EMF njengezintambo zikagesi. Ama-X-ray, nezinye izinqubo zokucabanga ngezokwelapha ezinjenge-MRIs, nawo atholakala enza ama-EMF.

Ngokusho kweBhange Lomhlaba, amaphesenti angama-87 wabantu emhlabeni anawo ugesi futhi asebenzisa izinto zikagesi namuhla. Lowo ugesi omningi nama-EMFs enziwe emhlabeni jikelele. Ngisho nawo wonke lawo magagasi, ososayensi ngokuvamile abacabangi ukuthi ama-EMF ayinkinga yezempilo.

Kepha yize iningi lingakholelwa ukuthi ama-EMF ayingozi, kusenososayensi abathile ababuza ukungachazeki. Abaningi bathi bekungekho ucwaningo olwanele lokuqonda ukuthi ngabe ama-EMF aphephile yini. Ake sihlolisise.

Izinhlobo zokuvezwa kwe-EMF

Kunezinhlobo ezimbili zokuvezwa kwe-EMF. Imisebe esezingeni eliphansi, ebizwa nangokuthi imisebe engeyona eye-ionizing, imnene futhi kucatshangwa ukuthi ayinabungozi kubantu. Izinto ezifana nezinto ezisebenza ngama-microwave, omakhalekhukhwini, ama-Wi-Fi routers, kanye nezintambo zikagesi nama-MRIs, zithumela imisebe esezingeni eliphansi.


Imisebe esezingeni eliphakeme, ebizwa ngemisebe ye-ionizing, uhlobo lwesibili lwemisebe. Ithunyelwa ngendlela yemisebe ye-ultraviolet evela elangeni kanye nama-X-ray avela emishinini yezithombe yezokwelapha.

Ukuqina kokuvezwa kwe-EMF kuyehla njengoba ukhuphula ibanga lakho entweni ethumela amagagasi. Eminye imithombo ejwayelekile yama-EMF, kusuka emisebeni esezingeni eliphansi kuya kweliphezulu, ifaka okulandelayo:

Imisebe engeyona ionizing

  • oveni bama-microwave
  • amakhompyutha
  • amamitha wamandla endlu
  • ama-routers angenantambo (Wi-Fi)
  • omakhalekhukhwini
  • Amadivayisi we-Bluetooth
  • izintambo zikagesi
  • Ama-MRIs

Imisebe ye-Ionizing

  • ukukhanya kwe-ultraviolet
  • Ama-X-ray

Ucwaningo ngobungozi

Kukhona ukungavumelani ngokuphepha kwe-EMF ngoba alukho ucwaningo olunamandla oluphakamisa ukuthi ama-EMF alimaza impilo yabantu.

Ngokwe-World Health Organisation's International Agency for Research on Cancer (IARC), ama-EMF "kungenzeka abe nomdlavuza kubantu." I-IARC ikholelwa ukuthi ezinye izifundo zikhombisa ukuxhumana okukhona phakathi kwama-EMF nomdlavuza kubantu.


Into eyodwa abantu abaningi abayisebenzisa nsuku zonke ethumela ama-EMF yiselula. Ukusetshenziswa komakhalekhukhwini kukhuphuke kakhulu selokhu bangeniswa ngawo-1980. Bekhathazekile ngempilo yabantu nokusetshenziswa komakhalekhukhwini, abacwaningi baqala ukuthi yini ezoba yinto yokuqhathanisa amacala omdlavuza kubasebenzisi bomakhalekhukhwini nakwabangewona ama-backus ngo-2000.

Abaphenyi balandele amazinga omdlavuza nokusetshenziswa kwamaselula kubantu abangaphezu kuka-5 000 emazweni ayi-13 emhlabeni jikelele. Bathola ukuxhumana okuxekethile phakathi kwezinga eliphakeme kakhulu lokuchayeka kanye ne-glioma, uhlobo lomdlavuza olwenzeka ebuchosheni nasentanyeni yomgogodla.

Ama-gliomas ayevame ukutholakala ohlangothini olufanayo lwekhanda abantu ababevame ukukhuluma ngalo ocingweni. Kodwa-ke, abacwaningi baphethe ngokuthi akukho ukuxhumana okuqinile okwanele ukuthola ukuthi ukusetshenziswa kwamaselula kubanga umdlavuza ezifundweni zocwaningo.

Ocwaningweni oluncane kodwa lwakamuva, abacwaningi bathole ukuthi abantu abadalulwe emazingeni aphezulu e-EMF iminyaka eminingi bakhombisa ingozi eyengeziwe yohlobo oluthile lwe-leukemia kubantu abadala.

Ososayensi baseYurophu babuye bathola ukuxhumana okusobala phakathi kwe-EMF ne-leukemia ezinganeni. Kepha bathi ukuqashwa kwe-EMF kuyashoda, ngakho-ke abakwazi ukuthola iziphetho ezithile emsebenzini wabo, futhi kudingeka olunye ucwaningo nokuqapha okungcono.

Ukubuyekezwa kwezifundo ezingaphezu kweshumi nambili kuma-EMFs anemvamisa ephansi kusikisela ukuthi le mikhakha yamandla ingadala izinkinga ezahlukahlukene zezinzwa nezengqondo kubantu. Lokhu kuthole ukuxhumana phakathi kokuvezwa kwe-EMF nezinguquko ekusebenzeni kwemizwa yomuntu emzimbeni wonke, kuthinta izinto ezifana nokulala nomoya.

Amazinga engozi

Inhlangano ebizwa nge-International Commission on Non-Ionizing Radiation Protection (ICNIRP) igcina imihlahlandlela yamazwe omhlaba yokuvezwa kwe-EMF. Le mihlahlandlela isuselwa kokutholakele kweminyaka eminingi yocwaningo lwesayensi.

Ama-EMF alinganiswa ngeyunithi ebizwa ngama-volts ngemitha ngayinye (V / m). Ukuphakama kwesilinganiso, i-EMF inamandla.

Izinto eziningi ezisebenza ngogesi ezithengiswa ngemikhiqizo ehlonishwayo zivivinya imikhiqizo yazo ukuqinisekisa ukuthi ama-EMF angena ngaphakathi kwemihlahlandlela ye-ICNIRP. Izinsiza zomphakathi nohulumeni banesibopho sokuphatha ama-EMF ahlobene nezintambo zikagesi, imibhoshongo yamaselula, kanye neminye imithombo ye-EMF.

Ayikho imiphumela yezempilo eyaziwayo elindelwe uma ukuvezwa kwakho ku-EMF kungaphansi kwamazinga kule mihlahlandlela elandelayo:

  • izinkambu zemvelo zikagesi (njengalezo ezidalwe yilanga): 200 V / m
  • amapayipi kagesi (angasondeli kolayini bamandla): 100 V / m
  • amapayipi kagesi (eduze kolayini bamandla): 10,000 V / m
  • izitimela zikagesi nezitimela: 300 V / m
  • Izikrini ze-TV nezekhompyutha: 10 V / m
  • Iziteshi ze-TV nezomsakazo: 6 V / m
  • iziteshi eziyisisekelo zamaselula: 6 V / m
  • ama-radar: 9 V / m
  • ama-microwave ovens: 14 V / m

Ungahlola ama-EMF ekhaya lakho ngemitha ye-EMF. Lawa madivayisi aphathwayo angathengwa ku-inthanethi. Kepha yazi ukuthi iningi alikwazi ukukala ama-EMFs amaza aphakeme kakhulu nokunemba kwawo ngokuvamile kuphansi, ngakho-ke ukusebenza kwawo kukhawulelwe.

Abaqaphi be-EMF abathengiswa kakhulu ku-Amazon.com bafaka amadivayisi aphathwayo abizwa ngama-gaussmeters, enziwe yiMeterk neTriField. Ungashayela inkampani yakho yamandla yangakini ukuhlela ukuhlela ukufundwa esizeni.

Ngokwe-ICNIRP, ukuvezwa kwabantu abaningi kakhulu ku-EMF kuphansi kakhulu empilweni yansuku zonke.

Izimpawu zokuvezwa kwe-EMF

Ngokwabanye ososayensi, ama-EMF angathinta ukusebenza komzimba wesistimu yakho futhi abangele ukulimala kwamaseli. Umdlavuza nokukhula okungajwayelekile kungaba uphawu olulodwa lokuchayeka okuphezulu kakhulu kwe-EMF. Ezinye izimpawu zingafaka:

  • ukuphazamiseka kokulala, kuhlanganise nokuqwasha
  • ikhanda
  • ukudana kanye nezimpawu zokudangala
  • ukukhathala nokukhathala
  • i-dysesthesia (ukuzwa okubuhlungu, okuvame ukubabaza)
  • ukungabi nokuhlushwa
  • izinguquko kwimemori
  • isiyezi
  • ukucasuka
  • ukulahlekelwa isifiso sokudla nokuncipha
  • ukungahlaliseki nokukhathazeka
  • isicanucanu
  • ukuvutha kwesikhumba nokushoshozela
  • izinguquko ku-electroencephalogram (elinganisa umsebenzi kagesi ebuchosheni)

Izimpawu zokuvezwa kwe-EMF azicaci futhi ukuxilongwa okuvela ezinkampanini akunakwenzeka. Okwamanje asazi ngokwanele ngemiphumela empilweni yomuntu. Ukucwaninga eminyakeni ezayo kungasazisa kangcono.

Ukuvikelwa ekuvezweni kwe-EMF

Ngokuya ngocwaningo lwakamuva, ama-EMF akunakwenzeka ukuthi abangele noma imiphi imiphumela emibi yezempilo. Kufanele uzizwe uphephile ngokusebenzisa umakhalekhukhwini wakho, nezinto ezisebenza ngogesi. Kufanele futhi uzizwe uvikelekile uma uhlala eduze kwezintambo zikagesi, njengoba imvamisa ye-EMF iphansi kakhulu.

Ukunciphisa ukuvezwa kwezinga eliphezulu nezingozi ezihambisanayo, thola kuphela ama-X-ray adingekayo kwezokwelapha futhi anciphise isikhathi sakho elangeni.

Esikhundleni sokukhathazeka ngama-EMF, kufanele umane ubazi futhi unciphise ukuvezwa. Beka ifoni yakho phansi uma ungayisebenzisi. Sebenzisa umsebenzi wesipikha noma ama-earbuds ngakho-ke akudingeki ukuthi ube ngendlebe yakho.

Shiya ifoni yakho kwelinye igumbi uma ulele. Musa ukuphatha ifoni yakho ephaketheni noma kubhodisi wakho. Qaphela izindlela ezingatholakala zokuvezwa nokukhishwa kumadivayisi kagesi nakugesi bese uya ekhempini kanye ngezikhathi ezithile.

Bheka izindaba nganoma yikuphi ukucwaninga okuthuthukayo ngemiphumela yazo yezempilo.

Ngezansi

Ama-EMF avela ngokwemvelo futhi aqhamuka emithonjeni eyenziwe ngabantu. Ososayensi bathole ukuxhumana okuthile okubuthakathaka phakathi kokuvezwa kwezinga eliphansi le-EMF nezinkinga zempilo, njengomdlavuza.

Ukuvezwa kwezinga eliphakeme le-EMF kwaziwa ngokudala izinkinga zemizwa nezomzimba ngokuphazamisa ukusebenza kwezinzwa zomuntu. Kodwa akunakwenzeka ukuthi uzovezwa kuma-EMFs anezinga eliphezulu kakhulu empilweni yakho yansuku zonke.

Yazi ukuthi ama-EMF akhona. Futhi hlakanipha ngokuvezwa kwezinga eliphezulu nge-X-ray nangelanga. Yize lokhu kuyinkambu yocwaningo ethuthukayo, akunakwenzeka ukuthi ukuvezwa kwezinga eliphansi kuma-EMF kuyingozi.
