Magwero a Magetsi Ochokera ku Magetsi
Pendauluan
Ma radiation amagetsi ndi mafunde a mphamvu omwe amayenda mumlengalenga kapena pazinthu. Ma electromagnetic spectrum amaphatikizapo mitundu yosiyanasiyana ya ma radiation, kuyambira mafunde a wailesi mpaka ma gamma rays, iliyonse yokhala ndi mafunde ndi ma frequency osiyanasiyana. Magwero a ma radiation amagetsi amatha kukhala achilengedwe kapena opangidwa ndi munthu. M'nkhaniyi, tifufuza magwero osiyanasiyana a ma radiation amagetsi ndi momwe amagwiritsidwira ntchito komanso momwe amakhudzira moyo watsiku ndi tsiku.
Magwero Achilengedwe a Magetsi a Magetsi
Magwero achilengedwe a mphamvu yamagetsi amachokera ku chilengedwe ndipo akhalapo kalekale ukadaulo wa anthu usanayambe. Zitsanzo zina za magwero achilengedwe ndi awa:
1. Dzuwa:
Dzuwa ndiye gwero lalikulu la kuwala kwa maginito padziko lapansi. Dzuwa limatulutsa mitundu yosiyanasiyana ya kuwala, kuphatikizapo kuwala kooneka, kuwala kwa ultraviolet (UV), ndi kuwala kwa infrared (IR). Kuwala kwa dzuwa kuchokera ku dzuwa n'kofunika kwambiri kuti thupi lipange vitamini D, koma kuwonetsedwa kwambiri kungayambitse kuwonongeka kwa khungu ndi khansa ya pakhungu. Kuwala kwa infrared kuchokera ku dzuwa kumatipatsa kutentha komwe timamva padziko lapansi.
2. Nyenyezi ndi Zinthu Zina Zakuthambo:
Kupatula Dzuwa, nyenyezi zina m'chilengedwe chonse zimatulutsanso ma radiation a elekitiromagineti. Ma radiation amenewa akuphatikizapo mitundu yosiyanasiyana, kuyambira mafunde a wailesi mpaka ma gamma rays. Ma telescope a wailesi ndi ma telescope a X-ray amagwiritsidwa ntchito poona ma radiation awa ndikuphunzira zochitika zakuthambo monga nyenyezi za neutron, mabowo akuda, ndi milalang'amba yakutali.
3. Mlengalenga wa Dziko Lapansi:
Mlengalenga wa Dziko Lapansi umatulutsa mphamvu ya maginito mu mawonekedwe a mafunde achilengedwe a wailesi, otchedwa mafunde a Schumann. Mafunde amenewa amayamba chifukwa cha mphezi yomwe imachitika mumlengalenga wa Dziko Lapansi. Mlengalenga umatulutsanso mphamvu ya infrared chifukwa cha kutentha kwa dzuwa.
4. Kuwala kwa Chilengedwe Chakuthambo:
Kuwala kwa cosmic background radiation ndi kuwala kwa electromagnetic komwe kunatsala kuchokera ku Big Bang, komwe kunapanga chilengedwe chathu. Kuwala kumeneku kuli ndi mafunde a microwave ndipo kumatha kuzindikirika ndi ma telescope apadera. Kuphunzira za kuwala kwa cosmic background radiation kumapereka chidziwitso cha chiyambi ndi kusintha kwa chilengedwe.
Magwero Opangidwa ndi Anthu a Mphamvu ya Magetsi
Kuwonjezera pa magwero achilengedwe, anthu apanga ukadaulo wosiyanasiyana womwe umatulutsa kuwala kwa maginito pazifukwa zosiyanasiyana. Zitsanzo zina za magwero opangidwa ndi anthu ndi izi:
1. Zipangizo Zamagetsi:
Zipangizo zamagetsi zambiri zomwe timagwiritsa ntchito tsiku lililonse zimatulutsa kuwala kwa maginito. Mafoni am'manja, makompyuta, ma TV, ndi ma Wi-Fi routers onse amatulutsa mafunde a wailesi ndi ma microwave. Zipangizozi zimagwiritsa ntchito kuwala kwa maginito polankhulana komanso kutumiza deta.
2. Zipangizo Zachipatala:
Ma radiation amagetsi amagwiritsidwa ntchito kwambiri m'zachipatala. Makina a X-ray amagwiritsidwa ntchito pojambula zithunzi, pomwe chithandizo cha ma radiation chimagwiritsa ntchito ma gamma rays pochiza khansa. MRI (Magnetic Resonance Imaging) imagwiritsa ntchito mafunde a wailesi ndi maginito kuti ipange zithunzi za thupi.
3. Zotumiza wailesi ndi wailesi yakanema:
Ma wailesi ndi wailesi yakanema amagwiritsa ntchito ma transmitter kutumiza zizindikiro za mafunde a wailesi kwa olandira m'nyumba mwathu. Ma transmitter amenewa amatulutsa mafunde amagetsi omwe amatha kunyamula mawu ndi zithunzi mlengalenga.
4. Satelayiti:
Ma satellite olumikizirana amatumiza ndikulandira ma microwave kuti atumize deta ku Dziko Lapansi. Ma satellite amenewa amalola kulumikizana padziko lonse lapansi, GPS, komanso kuwulutsa pa wailesi yakanema.
5. Radara:
Radar imagwiritsa ntchito ma microwave kuti izindikire ndikutsatira zinthu. Radar imagwiritsidwa ntchito mu ndege, kuyenda panyanja, nyengo, komanso usilikali. Ma microwave omwe amatulutsidwa ndi radar amadumphadumpha kuchokera ku zinthu ndikubwerera ku wolandila, zomwe zimapereka chidziwitso chokhudza mtunda ndi liwiro la chinthucho.
Kugwiritsa Ntchito Magetsi a Magetsi
Ma radiation amagetsi ali ndi ntchito zambiri zofunika pa moyo watsiku ndi tsiku komanso m'magawo osiyanasiyana aukadaulo. Zitsanzo zina za ntchito ndi izi:
1. Kulankhulana:
Ma wailesi ndi ma microwave amagwiritsidwa ntchito polankhulana opanda zingwe, kuphatikizapo mafoni am'manja, Wi-Fi, komanso ma wailesi ndi wailesi yakanema. Ukadaulo uwu umatilola kulankhulana nthawi yomweyo ndikupeza chidziwitso kuchokera padziko lonse lapansi.
2. Zithunzi Zachipatala:
Ma X-ray ndi ma MRI amagwiritsidwa ntchito popanga zithunzi za thupi zomwe zimathandiza madokotala kuzindikira ndi kuchiza matenda osiyanasiyana. Ukadaulo uwu wasintha kwambiri luso lozindikira matenda ndi chisamaliro chaumoyo.
3. Kuyenda:
Dongosolo loyendetsera GPS limagwiritsa ntchito ma satellite omwe amatumiza ma microwave kuti adziwe komwe tili padziko lapansi. GPS imagwiritsidwa ntchito m'magalimoto, mafoni am'manja, ndi mapulogalamu ena osiyanasiyana kuti atithandize kupeza njira yathu.
4. Chitetezo:
Makina a X-ray amagwiritsidwa ntchito m'mabwalo a ndege ndi malo ena kuti ayang'ane katundu ndikupeza zinthu zoopsa. Ukadaulo wa radar umagwiritsidwa ntchito poyang'anira ndi kuteteza dziko.
5. Kafukufuku wa Sayansi:
Ma telesikopu omwe amaona mitundu yosiyanasiyana ya kuwala kwa maginito amalola asayansi kuphunzira za chilengedwe chonse. Kafukufukuyu amapereka chidziwitso cha zochitika zachilengedwe ndipo amatithandiza kumvetsetsa chiyambi ndi kusintha kwa chilengedwe.
Zotsatira za Magetsi a Magetsi
Ngakhale kuti mphamvu ya maginito yamagetsi ili ndi ubwino wambiri, palinso zotsatirapo zoyipa zomwe ziyenera kuganiziridwa. Zina mwa zotsatirapozi ndi izi:
1. Thanzi:
Kukhudzidwa kwambiri ndi kuwala kwa dzuwa kuchokera ku dzuwa kungayambitse khansa ya pakhungu. Kukhudzidwa kwambiri ndi ma X-ray ndi ma gamma rays kungawononge minofu ya thupi ndikuwonjezera chiopsezo cha khansa. Chifukwa chake, ndikofunikira kuyang'anira ndikuchepetsa kukhudzidwa ndi kuwala kumeneku.
2. Kusokoneza kwa Magetsi (EMI):
Mafunde amagetsi ochokera ku chipangizo chimodzi amatha kusokoneza magwiridwe antchito a chipangizo china, chotchedwa electromagnetic interference (EMI). EMI ingayambitse mavuto akulu mu makina olumikizirana, ndege, ndi zida zamankhwala.
3. Chilengedwe:
Magwero ena a ma radiation amagetsi opangidwa ndi anthu, monga ma radio transmitters ndi radar, amatha kukhudza nyama zakuthengo. Ma radiation awa amatha kusokoneza kuyenda kwa nyama ndikukhudza zachilengedwe.
Mapeto
Magwero a ma radiation amagetsi ndi osiyanasiyana, kuphatikizapo magwero achilengedwe monga dzuwa ndi nyenyezi, komanso magwero opangidwa ndi anthu monga zida zamagetsi ndi ma radio transmitters. Ma radiation amagetsi ali ndi ntchito zambiri zofunika pakulankhulana, zamankhwala, kuyenda panyanja, chitetezo, ndi kafukufuku wasayansi. Komabe, ndikofunikira kumvetsetsa ndikuwongolera zotsatira zoyipa zomwe zingachitike chifukwa cha kuwonetsedwa ndi ma radiation amagetsi. Ndi chidziwitso choyenera, titha kugwiritsa ntchito bwino ma radiation amagetsi pomwe tikuchepetsa zoopsa zake.
