I-Lutetium oxide, obeye aziwe njengoI-Lutetium(III) oxide, iyinhlanganisela eyakhiwe yi-insimbi yomhlaba engavamilei-lutetiumkanye nomoya-mpilo. Inezinhlobonhlobo zezinhlelo zokusebenza zezimboni, okuhlanganisa ukukhiqizwa kwengilazi yokubona, ama-catalysts kanye nezinto zokwakha ze-nuclear reactor. Nokho, kuphakanyiswe ukukhathazeka mayelana nobuthi obungaba khona bei-lutetium oxideuma kukhulunywa ngomthelela ongaba khona empilweni yomuntu.
Ucwaningo ngemiphumela yezempilo yei-lutetium oxidekunqunyelwe ngoba kungokwesigaba seizinsimbi zomhlaba ezingavamile,ezithole ukunakwa okuncane uma kuqhathaniswa nezinye izinsimbi ezinobuthi njengomthofu noma i-mercury. Nokho, ngokusekelwe idatha etholakalayo, kungase kuphakanyiswe ukuthi ngenkathii-lutetium oxideingase ibe nezingozi ezithile zempilo ezingaba khona, izingozi ngokuvamile zibhekwa njengeziphansi.
I-Lutetiumakwenzeki ngokwemvelo emzimbeni womuntu futhi akubalulekile empilweni yomuntu. Ngakho-ke, njengabanyeizinsimbi zomhlaba ezingavamile, ukuchayeka ku-lutetium oxide kwenzeka ngokuyinhloko ezilungiselelweni zomsebenzi, njengendawo yokukhiqiza noma yokucubungula. Amathuba okuchayeka kubantu abaningi aphansi uma kuqhathaniswa.
Ukuhogela umoya nokuwungenisa kuyizindlela ezivame kakhulu zokuchayeka ku-lutetium oxide. Ucwaningo olwenziwe ezilwaneni ezihlolwayo lubonise ukuthi inhlanganisela inganqwabelana emaphashini, esibindini nasemathanjeni ngemva kokuhogela. Kodwa-ke, izinga lezi zithole ezingadluliselwa kubantu aliqiniseki.
Nakuba idatha ubuthi womuntui-lutetium oxidezilinganiselwe, izifundo zokuhlola ziphakamisa ukuthi ukuchayeka ekugxiliseni okuphezulu kungase kubangele eminye imiphumela emibi. Le miphumela ikakhulukazi ihlanganisa ukulimala kwamaphaphu nesibindi, kanye nezinguquko ekusebenzeni kokuzivikela komzimba. Kodwa-ke, kubalulekile ukuqaphela ukuthi lezi zifundo zivame ukubandakanya amazinga okuchayeka aphezulu kakhulu kunalawo atholakala ezimeni zomhlaba wangempela.
I-US Occupational Safety and Health Administration (OSHA) ibeka umkhawulo ovunyelwe wokuchayeka (i-PEL) we-lutetium oxide ku-1 mg kuyi-cubic meter yomoya ngosuku phakathi nosuku lomsebenzi lwamahora angu-8. Le PEL imele ukugcwala okuphezulu okuvumelekile kwe-lutetium oxide endaweni yokusebenza. Ukuchayeka emsebenzini kui-lutetium oxideingalawulwa ngempumelelo futhi incishiswe ngokusebenzisa izinhlelo ezifanele zokungenisa umoya kanye nemishini yokuzivikela yomuntu siqu.
Kubalulekile ukuqaphela ukuthi izingozi zempilo ezingaba khona ezihlobenei-lutetium oxideingancishiswa ngokuqhubekayo ngokulandela izindlela zokuphepha ezifanele kanye nemihlahlandlela. Lokhu kufaka phakathi izinyathelo ezinjengokusebenzisa izilawuli zobunjiniyela, ukugqoka izingubo ezivikelayo kanye nokuzilolongela ukuhlanzeka, njengokugeza izandla kahle ngemva kokubamba.i-lutetium oxide.
Kafushane, ngenkathii-lutetium oxideingase idale izingozi ezithile zempilo ezingaba khona, izingozi ngokuvamile zibhekwa njengeziphansi. Ukuchayeka emsebenzini kui-lutetium oxideingalawulwa ngempumelelo ngokusebenzisa izinyathelo zokuphepha kanye nokuthobela isiqondiso esinikezwa ama-ejensi alawulayo. Nokho, ngoba ucwaningo ngemiphumela yezempilo yei-lutetium oxideilinganiselwe, ucwaningo olwengeziwe luyadingeka ukuze kuqondwe kangcono ubuthi obungase bube khona futhi kusungulwe imihlahlandlela yokuphepha enembe kakhudlwana.
