N'oge na-adịbeghị anya, n'ihi nnukwu ntiwapụ nke ọrịa coronavirus ọhụrụ (2019-nCoV) na China, a na-amata ìhè UV maka ịdị irè ya n'igbu nje, na-aghọ ụzọ dị mkpa maka ịchịkwa mgbasa nke ọrịa ahụ na ịhụ nchekwa ndụ.
Ụkpụrụ mgbochi UV: A na-ekewa ọkụ UV n'ime A-band (315 ruo 400 nm), B-band (280 ruo 315 nm), C-band (200 ruo 280 nm), na vacuum UV (100-200 nm) dịka ogologo ogologo ya.N'ozuzu, a na-eji ọkụ C-band UV maka igba ogwu.Mgbe ekpughere ya na ọkụ C-band UV, nucleic acid (RNA na DNA) dị na microorganisms na-enweta ike nke UV photons, na-eme ka ụzọ abụọ isi mee polymerize ma gbochie njikọ protein, nke na-eme ka microorganisms enweghị ike ịmụpụta, si otú ahụ nweta nzube nke sterilization.
Uru nke UV Sterilisation:
