Ma hope o nā mahina o ka holoi lima lima lima ʻana, ka mamao ʻana o ka nohona, a me ka paʻa ʻana i ka pale maka, me he mea lā ua ʻeli ka coronavirus i kona mau māiʻuʻu no ka wā lōʻihi i ka U.S. A mai nā ʻāpana o kēia weliweli iā ʻoe hiki ʻo ka kāohi kāu hana ponoʻī a me kou wahi, ʻaʻole ia he mea kupanaha nāu - a me nā mea āpau āpau - ua lilo i mea hoʻomaʻemaʻe. Inā ʻaʻole ʻoe i hoʻopaʻa i ka Clorox a me ka holoi holoi disinfectant i Malaki, ua lilo paha ʻoe i mea akamai i ka hoʻokele ʻana iā Google e ʻimi i nā pane i nā nīnau e like me "hiki ke pepehi i nā maʻi maʻi?" aiʻole "ʻo ka vīnega kahi disinfectant?" ʻO kāu mau mikiona i lalo o ka lua lāpaki noiʻi i alakaʻi aku ai iā ʻoe i nā ala hou ʻē aʻe o ka luku ʻana i nā g germ: ʻo ia hoʻi, ke kukui ultraviolet (UV).

Ua hoʻohana ʻia ke kukui UV no nā makahiki he mau makahiki (ʻae, mau makahiki!) No ka hoʻohaʻahaʻa ʻana i ka laha o ka maʻi bacteria, e like me ka mea e hoʻoulu ai i ka maʻi maʻi, e like me ka US Food and Drug Administration (FDA). E like me kona hiki ke pepehi i nā g germ COVID-19? ʻAe, ʻaʻole i hoʻokumu maikaʻi ʻia. E hoʻomau i ka heluhelu ʻana e ʻike i ka ʻoiaʻiʻo i kākoʻo ʻia e ka poʻe akamai e pili ana i ke kukui UV, e pili ana inā ʻaʻole hiki ke pale maoli i ka lawe ʻana o ka coronavirus a me ka mea e ʻike e pili ana i nā huahana kukui UV (ʻo ia hoʻi nā kukui, nā kukui, a pēlā aku.) Ua ʻike ʻoe ma nā kaiapili āpau. .

Akā ʻo ka mea mua, he aha ke kukui UV?

ʻO ke kukui UV kahi ʻano uila radiation electromagnetic i lawe ʻia i nā nalu a i ʻole nā ​​ʻāpana i nā nalu like ʻole a me nā alapine, e hana ana i ka uila electromagnetic (EM), wahi a Jim Malley, Ph.D., he polofesa ʻenehana a me nā ʻenekinia kaiāulu ma ke Kulanui o. New Hampshire. ʻO ke ʻano maʻamau o ka pāhawewe UV? ʻO ka lā, kahi e hoʻopuka ai i ʻekolu ʻano mau kukuna: UVA, UVB, a me UVC, e like me ka FDA. Ua kamaʻāina ka hapa nui o ka poʻe i nā kukuna UVA a me UVB no ka mea ʻo lākou ka hewa no ka sunburns a me ka maʻi ʻili. (Pili: Pāhawewe Ultraviolet ke kumu o ka hōʻino ʻana o ka ʻili - ʻoiai ʻoe ma loko o ka hale)

ʻO nā kukuna UVC, ma ka ʻaoʻao ʻē aʻe, ʻaʻole e hana maoli i ka ʻilikai o ka Honua (nā poloka ozone e pale ai iā lākou), no laila ke hōʻike wale ʻia nei nā kānaka UVC māmā he mea ʻino ia, e like me ka FDA. Eia nō naʻe, mahalo nui ia; ʻO UVC, ka mea nona ka nalu lōʻihi loa a me ka ikehu kiʻekiʻe loa o nā radiation UV āpau, kahi disinfectant i ʻike ʻia no ka lewa, ka wai, a me nā papa nonporous. No laila, ke kamaʻilio nei e pili ana i ka disinfection kukui UV, aia ka manaʻo ma UVC, wahi a Malley. Eia ke kumu: i ka wā e hoʻokuʻu ʻia ai i kekahi mau hawewe a no nā manawa kikoʻī, hiki i ka kukui UVC ke hōʻino i ka genetic material - DNA a i ʻole RNA - i loko o nā maʻi bacteria a me nā maʻi maʻi, kaohi ʻana i ko lākou hiki ke hana hou a, ʻo ia hoʻi, e hoʻohiolo i kā lākou hana kelepona maʻamau. , Wehewehe 'o Chris Olson, microbiologist a me ka manakia papahana o ka pale maʻi maʻi a me ka mākaukau hoʻomākaukau ma UCHealth Highlands Ranch Hospital. (E hoʻomanaʻo: ʻOiai ʻo nā kukuna UVC mai nā kumu kūlohelohe hiki ke hoʻopilikia i ka wela o ka maka a me ka ʻili - e like me nā kukuna UVA a me UVB - ua kākoʻo ka FDA i kēia mau ʻeha "e hoʻoholo maʻamau i loko o hoʻokahi pule" a ʻo ka manawa e ulu ai ka maʻi maʻi ʻili. haʻahaʻa loa ia. ")

I mea e pono ai ka disinfection kukui UV, akā naʻe, pono e kāohi ʻia kekahi mau mea koʻikoʻi. ʻO ka mea mua, pono nā kukuna i nā nalu nalu pololei no ka maʻi virus. ʻOiai e hilinaʻi maʻamau kēia i ke kino kikoʻī, ma nā wahi āpau ma waena o 200-300 nm "manaʻo ʻia he germicidal" me ka hopena kiʻekiʻe ma 260 nm, wahi a Malley. Pono lākou i ka mahele kūpono - Hoʻonui ka ikaika o UV i ka nui o ka manawa hoʻopili, wehewehe ʻo ia. "ʻO ka lāʻau UV kūpono e pono ai ka laulā, ākea ma waena o 2 a me 200 mJ / cm2 e pili ana i nā kūlana kikoʻī, disinfected nā mea, a me ka pae i makemake ʻia o ka disinfection."

He mea nui nō hoʻi ka ʻole o ka wahi i nā mea e hiki ke hoʻopilikia i ka hiki ʻana o ke kukui UVC i ka pahuhopu, wahi a Malley. "Kuhi mākou i ka disinfection UV ma ke ʻano he ʻenehana laina laina, no laila inā i ālai kekahi mea i ke kukui UV me ka lepo, nā stains, nā mea e hoʻolei ana i nā aka a laila ʻaʻole e disinfected kēlā mau ʻāpana i pale ʻia a pale ʻia paha."

Inā ʻano paʻakikī kēlā, ʻo ia ka mea: "ʻAʻole maʻalahi ka disinfection UV; ʻaʻole like ka nui o nā mea āpau," wahi a Malley. A hoʻokahi wale nō kumu o ka maopopo ʻole o ka poʻe loea a me ka noiʻi i ka maikaʻi o ka hopena, inā paha, hiki ke kūʻē i ka coronavirus. (E nānā pū: Pehea e mālama ai i kou home maʻemaʻe a olakino inā ʻoe e mālama ʻia no ka Coronavirus)

Hiki ke hoʻohana ʻia ka disinfection kukui UV e kūʻē iā COVID-19?

He papa mele ko UVC no ka maikaʻi loa e kūʻē iā SARS-CoV-1 a me MERS, he mau hoahānau pili loa i ka SARS-CoV-2, ʻo ka maʻi hoʻomaʻamaʻa ke kumu iā COVID-19. Ua ʻike ʻia kekahi mau noiʻi, me nā hōʻike i haʻi ʻia e ka FDA, ua like paha ke kukui UVC i ka hopena like me SARS-CoV-2, akā ʻaʻole nui ka poʻe i loiloi nui ʻia. Eia kekahi, ua kaupalena ʻia nā ʻike i paʻi ʻia e pili ana i ka lōʻihi o ka lōʻihi, ka mahele lāʻau, a me ka lōʻihi o ka radiation UVC e koi ʻia ai e hoʻopau i ka maʻi SARS-CoV-2, e like me ka FDA. ʻO ke ʻano o ka noiʻi hou aʻe e pono ai ma mua o ka hiki ʻana i kekahi ke kūleʻa - a palekana - paipai i ke kukui UVC ma ke ʻano he ʻano hilinaʻi no ka pepehi ʻana i ka coronavirus.

ʻO ka ʻōlelo ʻana, ua hoʻohana nui ʻia nā kukui UV ma ke ʻano he sterilization i loko, no ka laʻana, ka ʻōnaehana olakino. ʻO kekahi o ia kumu? Ua ʻike ʻia kahi noiʻi e hiki i nā kukuna UVC keʻoki i ka lawe ʻana o nā superbugs nui (e like me staph) e 30 pākēneka. Hoʻohana nā haukapila he nui (inā ʻaʻole ka hapanui) i kahi lopako e hōʻike ana i UVC e like me ka nui o ka pahu hau lumi e hoʻopau ai i nā keʻena holoʻokoʻa, wahi a Chris Barty, he physicist a he polofesa hanohano o ka physics a me ka astronomy ma ke Kulanui o Kaleponi, Irvine. Ke haʻalele ka poʻe i ka lumi, hana ka hāmeʻa e hana i nā kukuna UV, hoʻoponopono iā ia iho i ka nui o ka lumi a me nā loli (ʻo ia hoʻi nā aka, nā wahi paʻakikī e hiki ai) e lawelawe i ke kukui no ka mea e pono ai. Hiki i kēia ke 4-5 mau minuke no nā lumi liʻiliʻi e like me nā lumi lumi a i ʻole 15-25 mau minuke no nā lumi nui, e like me Tru-D, hoʻokahi ʻano o kēia hāmeʻa. (FWIW, hana ʻia kēia me ka hoʻomaʻemaʻe lima me ka hoʻohana ʻana i nā disinfectants i ʻae ʻia e EPA.)

Hoʻohana kekahi mau keʻena lapaʻau i nā keʻena UVC me nā puka e hoʻopau i nā mea liʻiliʻi e like me iPads, kelepona, a me stethoscope. Ua hoʻokau maoli kekahi i kekahi mau mea UVC i kā lākou lewa lewa e hoʻopau pono ai i ka lewa, i ʻōlelo ʻo Olson - a, no ka mea ʻo COVID-19 e pālahalaha nui ma o nā ʻāpana aerosol, he mea kūpono kēia hoʻonohonoho. Eia nō naʻe, ʻaʻole i manaʻo ʻia kēia mau mea pono lāʻau lapaʻau no ka hoʻohana pākahi; ʻaʻole wale lākou i ke kumukūʻai, ke kumu kūʻai o $ 100k, akā koi lākou i kahi hoʻomaʻamaʻa kūpono no ka hana kūpono, hoʻohui ʻo Malley.

Akā inā ua hoʻolōʻihi ʻoe i ka manawa no ka noiʻi ʻana i nā disinfectants COVID-19, maopopo iā ʻoe aia ma kahi home nā hāmeʻa UV a me nā gizmos e pā ana i ka mākeke ma ka wikiwiki o ka maʻawe loloa i kēia manawa, nā mea āpau e hoʻomaʻemaʻe i ka hiki ke hōʻoluʻolu ʻia mai kou ʻoluʻolu home. (Pili: Nā 9 Huahana hoʻomaʻemaʻe kūlohelohe maikaʻi loa, e like me ka poʻe loea)

Pono ʻoe e kūʻai i nā huahana disinfection kukui UV?

"ʻO ka hapa nui o nā mīkini disinfection kukui UV home a mākou i nānā ai a hoʻāʻo ai [ma o kā mākou noiʻi ʻana ma ke Kulanui o New Hampshire] ʻaʻole e hoʻokō i nā pae o ka pepehi kanaka ʻana a lākou i koi ai i kā lākou mau hoʻolaha," wahi a Malley. "ʻO ka hapa nui o ka mana ma lalo o ka mana, hoʻolālā maikaʻi ʻole ʻia, a koi paha e pepehi i ka 99.9 pakeneka o nā g germ, akā ke hoʻāʻo mākou iā lākou e loaʻa pinepine lākou ma lalo o ka 50 pākēneka o ka luku ʻana i nā g germ." (E pili ana: 12 mau wahi e ulu ai nā maʻi e pono ai ʻoe e hoʻomaʻemaʻe RN)

ʻAe ʻo Barty, e ʻōlelo ana e hana maoli nā hāmeʻa i ka UVC, akā "ʻaʻole lawa e hana maoli i kekahi mea i ka nui o ka manawa i koi ʻia." E hoʻomanaʻo, no ka hoʻomālamalama maoli ʻana o ke kukui UV i nā ʻōpala, pono e hoʻomālamalama no kekahi manawa a me kahi lōʻihi o ka lōʻihi - a, i ka wā e luku pono ai i ka COVID-19, ʻo kēia mau ana ʻelua he TBD nō ia, e like me ka ʻO FDA.

ʻOiai ʻaʻole maopopo ka poʻe loea i ka hopena o nā pono disinfection UV e kūʻē i ka coronavirus, keu hoʻi no ka hoʻohana ʻana ma ka home, ʻaʻohe mea e hōʻole ana i ka hōʻike mua ʻana o ka pandemia, ua hōʻike ʻia ke kukui UVC (a hoʻohana ʻia hoʻi) e luku aku i nā meaola ʻē aʻe. No laila, inā makemake ʻoe e hāʻawi, e ʻōlelo, e hoʻāʻo ke kukui UV, hiki nō paha ia ke kōkua i ka hoʻolōʻihi ʻana i nā mikena ʻē aʻe e peʻe nei i kou home. Nā mea e noʻonoʻo ai ma mua o kou kūʻai ʻana:

ʻO Mercury kahi no-no. "Hoʻohana pinepine nā haukapila i nā kukui i hoʻokumu ʻia ma ka mercury no ka mea hiki iā lākou ke hana i nā kukui UVC a disinfect i kahi manawa pōkole," wahi a Barty. Akā, ICYDK, ʻawaʻawa ka mercury. No laila, koi kēia mau ʻano kukui UV i ke akahele i ka hoʻomaʻemaʻe a me ka hoʻolei ʻana, e like me ka FDA. Eia kekahi, hana nā kukui mercury i UVA a me UVB, kahi mea weliweli no kou ʻili. Nānā i nā hāmeʻa manuahi ʻole, e like me Casetify's UV sanitizer (Buy It, $120 $ 100, casetify.com) a i ʻole nā ​​mea i kapa ʻia ʻo "excimer-based," ʻo ia hoʻi hoʻohana lākou i kahi ʻano ʻokoʻa (sans-mercury) e hāʻawi i ke kukui UV.

E nānā i ka nalu lōʻihi.ʻAʻole like nā huahana UVC āpau - keu hoʻi i ka lōʻihi o ke kōā. E like me ka mea i ʻōlelo ʻia ma mua, hiki i ka nalu o UVC ke hoʻopili i ka pono o ka hāmeʻa i ka hoʻoulu ʻana i kahi maʻi (a pēlā e luku ai iā ia). Hiki paha iā ia ke hoʻopili i nā pilikia olakino a me nā palekana e pili ana me ka hoʻohana ʻana i ka hāmeʻa, e waiho ana iā ʻoe me ka hōʻaʻano o ka loaʻa ʻana o kahi uila disinfection light UV i lawa ka mana e hiki ai ke luku i nā maʻi maʻi me ka hōʻike ʻole ʻia o kahi pilikia olakino. No laila he aha ka helu kilokilo? Ma hea ma waena o 240-280 nm, e like me nā kikowaena no ka mālama ʻana i ka maʻi a me ka pale ʻana (CDC). ʻO ka mea i ʻōlelo ʻia, ua ʻike ʻia kahi noiʻi 2017 e hiki ana i nā nalu lōʻihi mai 207-222 nm ke kūpono a palekana hoʻi (ʻoiai, ʻaʻole maʻalahi e hele mai, e like me ka International Commission on Non-Ionizing Radiation Protection). TL; DR - inā hāʻawi ia iā ʻoe i ka maluhia o ka noʻonoʻo a i ʻole hōʻoluʻolu hoʻi e pepehi i kekahi mau mikena ma kāu kelepona, e hele no nā hāmeʻa e hoʻokuʻu aku, ma ka hapa nui, 280 nm.

E noʻonoʻo i kāu ʻili. ʻOi aku ka maikaʻi o ke kukui UVC ma nā mea paʻakikī, nā mea porous ʻole, e like me ka FDA. A maikaʻi ʻole ka maikaʻi ma luna o nā papa me nā puʻupuʻu a i ʻole nā ​​kualono, no ka mea paʻakikī kēia i ke kukui UV e hiki i nā wahi āpau e noho ai ka maʻi. No laila, ʻoi aku ka pono o ka disinfecting ʻana i kahi kelepona a i ʻole ka papakaukau ma mua o, e ʻōlelo, i kāu kapeta. A inā makemake ʻoe e nalu a puni kahi kukuna hoʻomaʻemaʻe kukui UV (Buy It, $ 119, amazon.com) me he mea lā he lightsaber ia, ʻo kāu koho maikaʻi loa e hana pēlā, no ka laʻana, kāu papa kīhini kīhini (manaʻo: ʻoluʻolu, nonporous , germy). 

Koho i nā huahana e pani. ʻO kahi mea uila e like me UV ʻaʻole ia kāu koho maikaʻi loa, wahi a Malley. "ʻAʻole pono e hōʻike pinepine nā kino ola (nā kānaka, nā holoholona, ​​nā mea kanu) i ke kukui UVC inā ʻaʻole ia i kahi hoʻonohonoho akahele me nā poʻe lapaʻau loea i hoʻomaʻamaʻa maikaʻi ʻia." ʻO ia no ka mea hiki i ka radiation UVC ke hōʻeha i nā maka o ka maka (e like me photophotokeratitis, kahi maka i hoʻomālamalama ʻia e ka lā) a me nā ʻā i kuni ʻia, e like me ka FDA. No laila ua hōʻike nā huahana māmā e like me ka wana a i ʻole ke kukui, koho i nā "hāmeʻa i hoʻopili ʻia" e hele mai me "nā hiʻohiʻona palekana (pani paʻa aunoa, a pēlā aku) ka hoʻopau ʻana i ka hiki ke hōʻike i nā mea ola e heʻe i ke kukui UVC," wahi a Malley. ʻO kahi koho maikaʻi: "He ipu no kāu kelepona, keu hoʻi inā waiho [kāu kelepona] ma laila no kahi manawa lōʻihi (ʻoiai e hiamoe ana)," e like me PhoneSoap's Smartphone UV Sanitizer (Buy It, $ 80, phoneoap.com).

Mai nānā i ka mālamalama. Ma muli o ka ʻike ʻole ʻia o ka hopena lōʻihi o UVC i nā kānaka, he mea nui e akahele loa i ka hoʻohana ʻana i kahi hāmeʻa. Hōʻalo i ka pili mau ʻana me ka ʻili a me ka hoʻokele i ka haka pono ʻana i ka mālamalama, ʻo ke kū pololei ʻana i ka radiation UVC e hōʻeha paha i nā ʻeha o ka maka a ʻeha hoʻi e like me ka ʻili, e like me ka FDA. Akā, ʻo ICYMI ma mua, nā polokalamu disinfection UV hiki iā ʻoe ke kūʻai mai i ka 'gram a ʻo Amazon paha, ma kā Malley mau huaʻōlelo, "underpowered" a hele mai me nā hiʻohiʻona pani pani ʻole, ka palena ʻana i nā pilikia. Eia nō naʻe, ʻoi aku ka makaʻala, e noʻonoʻo ana ʻaʻole maopopo iā mākou nā pilikia. (Pili: Hiki i ke kukui polū mai ka manawa pale ke hoʻopōʻino i kou ʻili?)

Laina lalo: "E ʻimi i kahi huahana me ka manual a ka mea hoʻohana i mākaukau pono, kikoʻī kikoʻī o ka mea a ka mea UV e hāʻawi ai no ka lāʻau, a me kekahi mau hōʻike o ka hoʻāʻo kūʻokoʻa ʻaoʻao ʻekolu e hōʻoia i nā kuleana hana i hana ʻia e ka huahana," ʻōlelo ʻo Malley.

A hiki i ka loaʻa ʻana o kahi noiʻi hou a me nā ʻike paʻa e hiki ai i ka kukui UVC ke pepehi maoli iā COVID-19, ʻoi aku paha ka maikaʻi o ka hoʻopili wale ʻana i ka hoʻomaʻemaʻe ma ka reg me nā huahana i ʻae ʻia e CDC, e hoʻomau i ka hana me ka mamao kaiāulu, a, e ʻoluʻolu e ʻaʻahu Mask 👏🏻.
