Umxholo

Sibandakanya iimveliso esicinga ukuba ziluncedo kubafundi bethu. Ukuba uthenga amakhonkco kweli phepha, sinokufumana ikhomishini encinci. Nantsi inkqubo yethu.

Ushwankathelo

Uninzi lwethu lusetyenziselwa izinto eziluncedo zobomi banamhlanje. Kodwa bambalwa kuthi abaziyo ubungozi obunokubakho bempilo obuboniswe zizixhobo ezenza umhlaba wethu usebenze.

Kuyavela ukuba iiselfowuni zethu, ii-microwave, ii-Wi-Fi routers, iikhompyuter, kunye nezinye izixhobo zithumela amaza ombane angabonakaliyo ezinye zeengcali ezixhalabileyo ngazo. Ngaba simele sixhalabe?

Ukusukela ekuqalekeni kwendalo iphela, ilanga lithumele amaza enza ugesi kunye nemagnethi (i-EMFs), okanye imitha. Kwangelo xesha ilanga lithumela ii-EMFs, sinokubona ukuphuma kwamandla alo. Oku kukukhanya okubonakalayo.

Ekupheleni kwekhulu lama-20, iintambo zombane kunye nezibane zangaphakathi zisasazeka kwihlabathi liphela. Izazinzulu ziye zaqonda ukuba iintambo zombane ezihambisa onke la mandla kubemi behlabathi bezikhupha ii-EMF, njengoko ilanga lisenza ngokwendalo.


Kule minyaka, izazinzulu ziye zafunda ukuba uninzi lwezixhobo ezisebenzisa umbane nazo zenza ii-EMFs njengezintambo zombane. IX-reyi, kunye nezinye iinkqubo zokucinga zonyango ezinje nge-MRIs, zafunyanwa zisenza ii-EMFs.

NgokweBhanki yeHlabathi, iipesenti ezingama-87 zabemi behlabathi banombane kwaye basebenzisa izixhobo zombane namhlanje. Umbane omninzi kunye nee-EMF ezenziwe kwihlabathi liphela. Ngaphandle kwawo onke loo maza, izazinzulu ngokubanzi azicingi ukuba ii-EMF ziyinkxalabo yezempilo.

Kodwa ngelixa uninzi lungakholelwa ukuba ii-EMF ziyingozi, kusekho izazinzulu ezithandabuza ukubhencwa. Uninzi luthi alukhange lubekho uphando olwaneleyo lokuqonda ukuba ngaba ii-EMF zikhuselekile. Makhe sijonge ngakumbi.

Iindidi zokuvezwa kwe-EMF

Zimbini iintlobo zokuvezwa kwe-EMF. Imitha yenqanaba elisezantsi, ekwabizwa ngokuba yimitha engeyiyo-ionizing, inobulali kwaye icingelwa ukuba ayinabungozi ebantwini. Izixhobo ezinje ngee-oveni ze-microwave, iiselfowuni, ii-Wi-Fi routers, kunye neendlela zombane kunye nee-MRIs, zithumela imitha yenqanaba elisezantsi.


Imitha ephezulu yemitha, ebizwa ngokuba yimitha ye-ionizing, luhlobo lwesibini lwemitha. Ithunyelwa ngendlela yemitha ye-ultraviolet evela elangeni kunye nee-X-ray ezivela koomatshini bokucinga ngezonyango.

Ukuqina kokuvezwa kwe-EMF kuyehla njengoko usonyusa umgama wakho kwinto ethumela amaza. Eminye imithombo eqhelekileyo ye-EMFs, ukusuka kwimitha ephantsi ukuya kwinqanaba eliphezulu, kubandakanya oku kulandelayo:

Imitha engasebenziyo

  • ii-oveni zemicrowave
  • iikhompyuter
  • Iimitha zamandla endlu
  • ii-wireless (Wi-Fi) imizila
  • oonomyayi
  • Izixhobo zeBluetooth
  • iintambo zombane
  • MRIs

Imitha yelanga

  • ukukhanya kwelanga
  • X-reyi

Uphando malunga nobungozi

Kukho ukungavumelani malunga nokukhuselwa kwe-EMF kuba akukho phando oluqinileyo olubonisa ukuba ii-EMF zenzakalisa impilo yabantu.

Ngokwe-Arhente yeHlabathi yezeMpilo yoPhando ngomhlaza (IARC), ii-EMFs "zibangelwa ngumhlaza ebantwini." I-IARC ikholelwa ukuba ezinye izifundo zibonisa unxibelelwano olunokwenzeka phakathi kwe-EMFs kunye nomhlaza ebantwini.


Inye into abantu abaninzi abayisebenzisa yonke imihla ethumela ii-EMFs yiselfowuni. Ukusetyenziswa kweeselfowuni kunyuke ngokubonakalayo ukusukela oko zaziswa ngeminyaka yoo-1980. Ukuxhalaba ngempilo yabantu kunye nokusetyenziswa kweeselfowuni, abaphandi baqala into eya kuba kukuthelekisa iimeko zomhlaza kubasebenzisi beeselfowuni kunye nabangasebenzisiyo ngo-2000.

Abaphandi balandela amaqondo omhlaza kunye nokusetyenziswa kweeselfowuni kubantu abangaphezulu kwama-5 000 kumazwe ali-13 kwihlabathi liphela. Bafumene unxibelelwano olukhululekileyo phakathi kwelona zinga liphezulu lokuvezwa kunye ne-glioma, uhlobo lomhlaza olwenzeka kwingqondo kunye nentambo yomqolo.

Iigliomas zazifumaneka kwicala elinye lentloko abantu babedla ngokuthetha ngazo emnxebeni. Nangona kunjalo, abaphandi bagqiba kwelokuba kwakungekho unxibelelwano olomeleleyo ngokwaneleyo lokufumanisa ukuba ukusetyenziswa kweeselfowuni kubangela umhlaza kwizifundo zophando.

Kwisifundo esincinci kodwa esandula ukwenziwa, abaphandi bafumanise ukuba abantu abatyhilekileyo kumanqanaba aphezulu e-EMF kangangeminyaka ngexesha babonisa ukwanda komngcipheko wohlobo oluthile lweleukemia kubantu abadala.

Izazinzulu zaseYurophu zikwafumanise unxibelelwano olubonakalayo phakathi kwe-EMF kunye neleukemia ebantwaneni. Kodwa bathi ukubeka esweni i-EMF kuyasilela, ke abakwazi ukufikelela kwizigqibo ezithile emsebenzini wabo, kwaye kufuneka uphando ngakumbi kunye nokubeka iliso ngcono.

Uphengululo lwezifundo ezingaphezulu kweshumi elinambini kwii-EMFs ezisezantsi zibonisa ukuba ezi ndawo zinamandla zinokubangela iingxaki ezahlukeneyo ze-neurological and psychiatric ebantwini. Oku kufumene ikhonkco phakathi kokuvezwa kwe-EMF kunye notshintsho ekusebenzeni kwemithambo-luvo emzimbeni wonke, ichaphazela izinto ezinje ngokulala kunye nomoya.

Amanqanaba engozi

Umbutho obizwa ngokuba yiKhomishini yeHlabathi yoKhuseleko lweMitha engasebenziyo (ICNIRP) igcina izikhokelo zamanye amazwe zokuvezwa kwe-EMF. Ezi zikhokelo zisekwe kwiziphumo zeminyaka emininzi yophando lwenzululwazi.

Ii-EMF zilinganiswa kwiyunithi ebizwa ngokuba yi-volts kwimitha nganye (V / m). Ukunyuka komlinganiso, kokukhona i-EMF yomelele.

Uninzi lwezixhobo zombane ezithengiswa ziimpawu ezaziwayo zivavanya iimveliso zazo ukuqinisekisa ukuba ii-EMF ziwela ngaphakathi kwezikhokelo ze-ICNIRP. Izixhobo zikarhulumente noorhulumente banoxanduva lokulawula ii-EMFs ezinxulumene neentambo zombane, iinqaba zeselfowuni, kunye neminye imithombo ye-EMF.

Akukho ziphumo zempilo zilindelekileyo ukuba ukubonakaliswa kwakho kwi-EMF kwehla ngaphantsi kwamanqanaba kwezi zikhokelo zilandelayo:

  • iinkalo zendalo zombane (njengalezo zenziwe lilanga): 200 V / m
  • umbane wombane (ungasondeli kwiintambo zombane): 100 V / m
  • umbane (kufutshane neentambo zombane): 10,000 V / m
  • oololiwe bombane kunye neetramu: 300 V / m
  • Izikrini zeTV kunye nekhompyuter: 10 V / m
  • Izixhobo zeTV kunye nerediyo: 6 V / m
  • Izikhululo zeefowuni eziphathwayo: 6 V / m
  • Iiradar: 9 V / m
  • ii-oveni ze-microwave: 14 V / m

Ungajonga ii-EMF ekhaya lakho ngeemitha ze-EMF. Ezi zixhobo ziphathwayo zingathengwa kwi-Intanethi. Kodwa yazi ukuba uninzi alunakulinganisa ii-EMF zamaza aphakamileyo kakhulu kwaye ukuchaneka kwawo kuphantsi ngokubanzi, ke ukusebenza kwawo kulinganiselwe.

Abona bahloli be-EMF abathengiswa kakhulu kwi-Amazon.com kubandakanya izixhobo eziphathwayo ezibizwa ngokuba zii-gaussmeters, ezenziwe yiMeterk kunye neTriField. Ungatsalela umnxeba inkampani yakho yamandla ekucwangciseni ukufundwa kwindawo.

Ngokwe-ICNIRP, ukuvezwa kwabantu abaninzi kwi-EMF kuphantsi kakhulu kubomi bemihla ngemihla.

Iimpawu zokuvezwa kwe-EMF

Ngokwezinye izazinzulu, ii-EMFs zinokuchaphazela ukusebenza kwenkqubo yemithambo-luvo yomzimba wakho kwaye zibangele ukonakala kweeseli. Umhlaza kunye nokukhula okungaqhelekanga kunokuba luphawu olunye lokuvezwa okuphezulu kwe-EMF. Ezinye iimpawu zingabandakanya:

  • ukuphazamiseka kokulala, kubandakanya ukulala
  • intloko ebuhlungu
  • uxinzelelo kunye neempawu zokudakumba
  • ukudinwa nokudinwa
  • I-dysesthesia (ubuhlungu, buhlungu rhoqo)
  • ukungabikho kwengqwalaselo
  • utshintsho kwimemori
  • isiyezi
  • ukucaphuka
  • ukuphelelwa ngumdla wokutya kunye nokwehla kobunzima
  • ukuphumla kunye noxinzelelo
  • isicaphucaphu
  • ukutshisa kwesikhumba kunye nokugungqa
  • utshintsho kwi-electroencephalogram (eyenza amanyathelo ombane kwingqondo)

Iimpawu zokuvezwa kwe-EMF azicacanga kwaye ukuxilongwa kwiimpawu akunakulindeleka. Okwangoku asazi ngokwaneleyo malunga neziphumo kwimpilo yabantu. Uphando kule minyaka izayo lungasazisa ngcono.

Ukukhuselwa ekuvezweni kwe-EMF

Ngokophando lwamva nje, ii-EMFs akunakulindeleka ukuba zibangele naziphi na iziphumo ezibi kwezempilo. Kuya kufuneka uzive ukhuselekile usebenzisa iselfowuni, kunye nezixhobo. Kuya kufuneka uzive ukhuselekile ukuba uhlala kufutshane neelayini zombane, njengoko frequency ye-EMF isezantsi kakhulu.

Ukunciphisa ukubonakaliswa okuphezulu kunye nobungozi obunxulumene noko, fumana kuphela ii-X-ray eziyimfuneko kwezonyango kwaye unciphise ixesha lakho elangeni.

Endaweni yokukhathazeka nge-EMF, kuya kufuneka ubazi kwaye unciphise ukubonakaliswa. Beka ifowuni yakho phantsi xa ungayisebenzisi. Sebenzisa umsebenzi wesithethi okanye i-earbuds ukuze kungabikho ngendlebe yakho.

Shiya ifowuni yakho kwelinye igumbi xa ulele. Musa ukuphatha ifowuni yakho epokothweni okanye kwibra yakho. Qaphela iindlela ezinokubakho zokuvezwa kunye nokukhupha izixhobo zombane kunye nombane kwaye uye ekampini kanye ethubeni.

Gcina iso kwiindaba zalo naluphi na uphando olwenziwayo malunga nefuthe labo lezempilo.

Okukwintsusa

Ii-EMF zenzeka ngokwendalo kwaye zivela kwimithombo eyenziwe ngabantu. Oososayensi bafumene unxibelelwano olunokubuthathaka phakathi kokuvezwa kwenqanaba eliphantsi le-EMF kunye neengxaki zempilo, njengomhlaza.

Ukuvezwa kwinqanaba le-EMF ekumgangatho ophakamileyo kuyaziwa ukuba kubangele iingxaki ze-neurological and physiological ngokuphazamisa ukusebenza kwentliziyo yomntu. Kodwa akunakulindeleka ukuba ube nokuvezwa kwii-EMFs ezihamba rhoqo kubomi bakho bemihla ngemihla.

Qaphela ukuba ii-EMF zikhona. Yiba nobulumko malunga nokuvezwa kwinqanaba eliphezulu ngeX-reyi kunye nelanga. Ngelixa eli licandelo lophando elikhulayo, akunakulindeleka ukuba ukubonakaliswa kwinqanaba eliphantsi kwii-EMF kuyingozi.
