AMVOJI ELEKTROMAGNITi

AMVOJI ELEKTROMAGNITi, afkanishoti elektromagniti, tagyiri maydoni elektromagniti, ki dar fazo bo surati nihoi (okhirnok) pahn meshavad., afkanishoti elektromagniti, tagyiri maydoni elektromagniti, ki dar fazo bo surati nihoi (okhirnok) pahn meshavad. Ba afkanishoti elektromagniti mavjhoi radio (mavjhoi daroz, miyona, kutoh, ultrakutoh va mikromavjho), afkanishoti garmi (shuohoi infrasurkh, rushnoii ba chashm namoyon va shuohoi ultrabunafsh), afkanishoti ionzo ( nurhoi rentgeni va gammanurho) mansuband.
Tasiri biologii A. e.-ro khususiyathoi mavju kvantho muayyan mekunand. Hosiyati mavjho az surati pahnshavi dar fazo (dar atmosfera taqr. ba 300 000 km/son. barobar buda, baroi hamai A. e. yak khel ast), basomadi lappishi maydon va darozii mavj iborat ast. Basomadi lappishro bo gertsho (gs) chen mekunand (gerts in yak lappishest dar yak son). Buzurgihoi hosilavi inhoyand: kilogerts (Kgs) – 1 haz. gs; megagerts (Mgs) – 1 mln. gs; gegagerts (Ggs) – 1 mlrd. gs. Darozii mavjho bo kilometr (km), metr (m), ditsimetr (dm), santimetr (sm), millimetr (mm), mikrometr (mkm) va nanometr (nm) chen karda meshavad.
Hususiyathoi kvantii A. e. bo afkanishoti elektromagniti dar shakli hissahoi alohidai elementari – kvantho (fotonho) muayyan karda meshavand. Kvanti elektromagniti energiyai muayyan dorad. Buzurgii energiya ba basomadi lappish vobasta ast; basomadi lappishi maydoni elektromagniti har qadar kalon boshad, energiyai kvant hamon qadar ziyod ast va on bo elektronvolt (EV)-ho ifoda meyobad.
Rohhoi tasiri A. e. ba organizmi odam murakkabu gunogun buda, to hol purra omukhta nashudaand. Ba badani odam pahn shudani mavjho ba monandi dar fazo pahn gashta, az ashyoi atrof inikos yoftani onho ba darozii mavjho va namudi afkanishot vobasta ast. Faoliyati biologii mavjhoi radio barobari kam shudani darozii mavj meafzoyad. YAk qismi energiyai radiomavjhoi ba organizm voridshudaro boftaho furu mebarand. Dar natijai in garmii ziyod judo meshavad. Mas., agar chashm, ki raghoyash nisbatan kamtarand, az mikroamvoji darozii mavjashon 10 – 12 santimetra oseb yobad, pas harorati qismi aqibi zujojiya 200S meafzoyad va khudi chashm khira meshavad (nig. Katarakta). Hangomi tasiri doimii A. e.-i pastshiddat odam khastagi ehsos namuda, qobiliyati kori sust meshavad, sar goh – goh dard mekunad, tab khira va asab kharob ast. Baze odamon az seraraqi, sust shudani quvvai hofiza, nafastangi, dardi dil shikoyat mekunand. Dar in guna holatho favran ba dukhtur murojiat boyad kard. Dar asnoi bo manbai mavjhoi radio saru kor doshtan baroi tamini bekhatarii kor az usulu vasoiti zamonavii hifozat istifoda burda meshavad.
Korgarone, ki doimo bo A. e. sarukor dorand, tahti nazorati tibbi meboshand. Ba korhoi marbut ba A. e. odamon boyad vobasta ba kasb qabul karda shavand. Nig. niz Afkanishoti ionzo, Nurshifoi, Barqshifoi.
