He maikaʻi anei ke kukui UVC no nā maʻi maʻi a me nā maʻi?

ʻO nā maʻi bacteria a me nā maʻi maʻi he microorganism microscopic hiki ke hoʻoulu i nā maʻi like ʻole

kūlana. No ka pale ʻana i ka lawe ʻia ʻana o ia mau maʻi a me nā maʻi, pono e hoʻopau ʻia kēia mau microorganism mai ka ʻili a me ka ea. ʻO ka hoʻohana ʻana i ka radiation ultraviolet (UV) kekahi ala kūpono no ka hoʻokō ʻana i kēia. kukui UVC ua hōʻike ʻia ʻo ia ke ʻano maikaʻi loa o ke kukui UV no ka luku ʻana i nā maʻi bacteria a me nā maʻi. E wehewehe kikoʻī kēia ʻatikala i ke ʻano o ka radiation ultraviolet C (UVC), pehea ia e hana ai, a pehea ka maikaʻi o ka pepehi ʻana i nā maʻi bacteria a me nā maʻi.

He hawewe nalu ka UVC ma waena o 200 a me 280 nanometers (nm). ʻOi aku ka pōkole o ka nalu ma mua o ka mālamalama ʻike ʻia, a me ka UVA a me ka UVB radiation mai ka lā a mākou e ʻike ai.

Pehea e hana ai ke kukui UVC?

Hana ʻia ka radiation UVC ma o ka hoʻopōʻino ʻana i ka DNA i nā microorganism e like me ka bacteria a me nā maʻi. ʻO kekahi o nā nucleotides ʻehā i loaʻa i ka DNA, thymine, e hana i nā mea paʻa covalent me nā molekole thymine pili i ka wā e ʻike ʻia ai i ka radiation UVC. ʻO kēia ka hopena i ka hoʻokumu ʻana i kahi dimer thymine, kahi e hoʻohuli ai i ke ʻano helix DNA a pale i ka hana hou ʻana o DNA. ʻAʻole hiki i ka microorganism ke hoʻomanawanui a hana hou me ka hiki ʻole ke hana hou.

Pono ka radiation UVC i ka nalu kūpono a me ka ikaika e pono ai. kukui UVC  ana ka ikaika ma microwatts no ke kenimika huinaha (W/cm2). Pono ka ikaika e hoʻopau i ka maʻi bacteria a me nā maʻi maʻi e pili ana i ke ʻano o ka microorganism, ka mamao ma waena o ke kumu kukui a me ka microorganism, a me ka lōʻihi o ka ʻike.

UVC Radiation a me Bakteria

Ua hōʻike ʻia ke kukui UVC e kūʻē i nā ʻano maʻi bacterial. Ma kekahi haʻawina, kukui UVC ua hoemi i ka heluna o ka ma'i bacteria Staphylococcus aureus ma ka ili e 99.9% ma hope o 5 kekona wale no o ka ike ana i ka 0.32 W/cm2 o ke kukui UVC. Hoʻokahi minuke o ka ʻike ʻana i ke kukui UVC me ka ikaika o 1.8 W / cm2 ua lawa ia e hoʻopau i ka 99.9% o ka bacteria Pseudomonas aeruginosa, e like me kekahi noiʻi.

kukui UVC ua hōʻike ʻia hoʻi e hoʻopau i nā hua bacteria multidrug-resistant. Ma hoʻokahi haʻawina, ʻo 10 mau kekona o ka ʻike ʻana i ke kukui UVC ma ka ikaika o 0.2 W/cm2 ua hoʻemi ʻia ka nui o nā maʻi bacteria Acinetobacter baumannii multidrug-resistant ma kahi ʻili e 99.9%. 5 kekona o ka hoolaha ana i 0.5 W/cm2  kukui UVC t hoemi i ka heluna o ka ma'i bacteria Klebsiella pneumoniae multidrug-resistant ma ka ili e 99.9%, e like me ka hoao ana.

UVC Radiation a me Virus

ʻIke ʻia ke kukui UVC e kūʻē i nā maʻi like ʻole. I loko o 15 mau minuke, kukui UVC  me ka ikaika o 0.1 W/cm2 i hoemi i ka infectivity o ka influenza A virus e 99.99%, e like me kekahi noiʻi. Ma kahi haʻawina ʻē aʻe, 15 mau minuke o ka ʻike ʻana i kukui UVC me ka ikaika o 0.5 W/cm2 i hōʻemi i ka maʻi maʻi o ke kanaka coronavirus OC43 e 99.9%.

Ua hōʻike ʻia hoʻi i ka maikaʻi e kūʻē i ka maʻi maʻi SARS-CoV-2 kumu COVID-19 ma o Lākou ir di ka maʻi maʻi . I loko o 25 kekona, kukui UVC  me ka ikaika o 0.1 W/cm2 i hōʻemi i ka infectiousness o ka maʻi SARS-CoV-2 e 99.9%, e like me kahi noiʻi. Ma kahi haʻawina ʻē aʻe, ʻike ʻia i kukui UVC me ka ikaika o 0.05 W/cm2 i hōʻemi i ka maʻi maʻi o ka maʻi SARS-CoV-2 e 99.9% i hoʻokahi minuke wale nō.

Pono e hoʻomaopopo i ka pono o ka   ʻo ia i ka luku ʻana i nā maʻi maʻi e pili ana i nā ʻano like ʻole, me ke ʻano o ka maʻi virus, ka ikaika o ka mālamalama, a me ka lōʻihi o ka hoʻolaha ʻana. Eia nō naʻe, ua hōʻike ʻia ka noiʻi hiki i ka kukui UVC ke lilo i mea pono no ka pale ʻana i ka hoʻolaha ʻana o nā maʻi e like me ka maʻi influenza, nā coronaviruses kanaka, a me SARS-CoV-2.

Kaohi ʻana i ke kukui UVC

Ua hōʻike ʻia ke kukui UVC i ka maikaʻi o ka pepehi ʻana i nā microbes a me nā maʻi maʻi, akā ua kaupalena ʻia kāna noi.

●  ʻO ka mea mua, hiki ke pepehi wale ʻia nā microorganism i ʻike pono ʻia iā ia me ka Donmake hkonKah . No laila, hiki i nā ʻili a me nā mea pili ʻole me ka radiation UVC ke hoʻopaʻa mau i ka bacteria a me nā maʻi.

●  ʻO ka lua, ʻo ka ʻike pololei ʻana iā ia no ka manawa lōʻihi e hiki ke hōʻeha i ke kanaka. No laila, pono e hoʻopili i nā alakaʻi palekana UVC a me ka hōʻoia ʻaʻole i ʻike pololei ʻia nā kānaka i ka mālamalama.

●  ʻO ke kolu, hiki iā ia ke luku wale i ka bacteria a me nā maʻi inā hoʻohana ʻia me ka ikaika a me ka lōʻihi. ʻAʻole maikaʻi paha ia i ka hoʻopau ʻana i nā microorganism inā ʻaʻole lawa ka ikaika a i ʻole ka lōʻihi o ka hoʻolaha ʻana.

●  ʻO ka hope, ʻaʻole maikaʻi paha ka radiation UVC i nā maʻi bacteria a me nā maʻi. Hiki paha i kekahi mau microorganism a me nā maʻi ke kūʻē i ka kukui UVC ma mua o nā mea ʻē aʻe.

ʻAʻole like nā kukui UV āpau!

ʻAʻole like ka maikaʻi o ka radiation UV a pau i ka luku ʻana i nā maʻi bacteria a me nā maʻi. Aia nā ʻano like ʻole o nā ʻano kukui UV, kēlā me kēia me nā lōʻihi nalu a me nā waiwai. No ka hoʻomaopopo ʻana i nā ʻokoʻa ma waena o nā ʻano kukui UV, pono e nānā i ka spectrum ultraviolet.

UV-A a me UV-B

ʻO UV-A a me UV-B nā ʻano i ʻike nui ʻia o ke kukui ultraviolet, a ʻo ia nā kukuna o ka lā i hiki i ka ʻili o ka Honua. Eia nō naʻe, hoʻohana mau ʻia nā ʻano kukui UV ʻē aʻe i nā huahana e hoʻopau i ka ea.

UV-C

ʻO UV-C, i kapa ʻia ʻo germicidal UV, aia nā hawewe ma waena o 200 a me 280 nanometers. ʻO kēia ke ʻano maʻamau o germicidal UV i hoʻohana ʻia e nā ʻepekema no hoʻokahi haneli mau makahiki e hoʻopau i ka wai, ka ea, a me nā ʻili. Hoʻopau maikaʻi a hoʻopau ʻo UV-C i nā ʻano microorganism āpau, me nā maʻi maʻi, bacteria, mold, a me nā haʻi.

mamao-UVC

ʻO Far-UVC kahi ʻāpana o UV-C, nona nā lōʻihi nalu ma waena o 207 a me 222 nanometers. He ʻokoʻa ka Far-UVC no ka mea i manaʻo ʻia he mea ʻole ia no ka ʻike kanaka. ʻO kēia kikoʻī kikoʻī o ka māmā he bandwidth haiki loa e pale aku ai i ke komo ʻana ma waho o ka papa o waho o ko mākou epidermis, akā hiki nō ke pepehi i nā maʻi a me nā maʻi bacteria. I nā makahiki i hala iho nei, ua hoʻomaka ka poʻe ʻepekema i ka nānā ʻana i ka mamao-UVC, no laila ʻoi aku ka palena o ka noiʻi ʻana i nā hopena ʻino ma mua o UV-C.

Ma kahi o UV

ʻO Near UV ka nui o nā lōʻihi hawewe UV-A, nona kekahi mau mea pepehi germ akā ʻaʻole hiki ke luku i nā maʻi e like me UV-C. Ma nā keʻena lapaʻau a me nā keʻena mālama makua, kokoke i ke kukui ultraviolet hiki ke kōkua i ka hōʻemi ʻana i ka nui o ka maʻi bacterial. Kokoke loa kēia mau hawewe i ke ʻano o ka mālamalama ʻike ʻia a manaʻo ʻia he palekana no nā kānaka.
