Radiation pōkākā

hipokina radiation hiko pōkākā ranei te rohe spectral i waenganui i te ngaru hiko, e kite i te kanohi tangata, me tona pito whero me te ngaruiti ranei ngaruiti radiation. Ko te rerekētanga nui i roto i te āhuatanga optical o matū kitea i waenganui i te perception i roto i te marama pōkākā, me te kitea. Hei tauira, mō te poto-poipoi iraruke pōkākā i roto i te wai e rave rahi henimita matotoru puatakore.

Mō 50% o te radiation solar taka i runga i tenei momo. Ko reira wahi o te huna me te aano atu rama rite pai rite etahi lasers taea o emitting radiation pōkākā. Hei te rēhita reira, te whakamahi i photovoltaic me farii waiariki ranei whakaahua motuhake.

I roto i te whānuitanga o te iraruke pōkākā e toru wāhanga: poto-poipoi, reo-poipoi, me te rohe roa-poipoi. E wehea wavelengths roa ki sublimated terahertz ranei radiation.

Ka kite kiri Human radiation pōkākā i ngā wera, kia rite ki te sensation ngāwhā, pera kua huaina hoki a reira "wera." Ko te roangaru itehia i wera, tei runga i te pāmahana whakawera. Ki te he nui te pāmahana, he poto te roangaru, me te kaha o tona paheke i runga. Ko te katote oaoa me ngota emit radiation pōkākā. I roto i tēnei awhe, i pāmahana āhua iti, me te he hiko radiation tūāwhiorangi blackbody.

kitea arorangi William Herschel radiation hiko i roto i te 1800, i muri i nei te marama pōkākā i ako kua i roto i te taipitopito. Ko tōna āhuatanga Herschel takoto te whakamahi i ngā inepāmahana. Ka rite ki te hua o ngā, i whakakitea ai e rerekē wahi o nga mahi tūāwhiorangi pāmahana kitea rerekē. Kua tāutuhia e Herschel te whai ake: te wera mōrahi, e takoto i waho te tae kukū whero, he mea e ahei, me te reira ata tāhapa kitea.

taiwhanga Modern puna o radiation pōkākā hāngai e i mārō-āhua rāpoi lasers hau. He ratou te whakarite, me te pūmau auau paheke.

Hei te rēhita waiariki radiation papa paraharaha, whakaahua motuhake whakamahia. E Photoresistor pūoko-hiko, me te whānuitanga nui whānui o te tūtohutanga.

He te kaha rerekē ki te radiation pōkākā. He penei e taea te whakamahi i te reira i roto i ngā mara ona āhuatanga:

• rongoā - i roto i te tua;
• sterilization o ngā hua kai mō te disinfection;
• mana mamao - i roto i ngā mana mamao pouaka whakaata, ngā pūnaha aunoa me te haumaru, te tahi mau tauira o waea pūkoro;
• painting - whakapaua pūngao, me te he nui raro atu i ki tikanga iakawe te auau;
• hei māngai anti-waikura;
• ahumahi kai - ngaru hiko etahi ngā whai pānga waiariki, me te koiora i runga i te hua, e āwhina whakatere panoni matüora i roto i biopolymers;
• ahumahi ahuwhenua;
• ara whakawera wāhi whare ranei ki te whakawera matua, me te atu;
• taki i te pono o te moni, me ētahi atu

Ka taea e radiation Pōkākā meinga kino ki kanohi tangata. I roto i aua wahi i reira i reira he wera nui, ka taea e radiation pōkākā e mōrearea mo te kanohi, me te mea kahore i haere tahi ai i te puna te marama kitea. I roto i enei wā ko reira e tika ana ki te whakamahi i mōwhiti tiaki.

I roto i te tahi atu te wā, pōkākā radiation take kino ki kore e taea e te tangata. Ko reira haumaru tino me e kore e whai tetahi rite ki te hihi katinga X-hihi ranei.

radiation Pōkākā, whakamahia hoki te tunu, hanga kai he tino reka, kia rite ki reira katoa o nga kohuke me huaora kei tonu, ki te ngaruiti, e kore te reira e whai tetahi ki te mahi i.

I roto i te whānui taea tatou te mea e tata tetahi o nga wāhi te wahi e kore e te whakamahia te radiation pōkākā i teie mahana.
