Effects of some physico-chemical factors on antimicrobial efficiency of ultra violet radiation

Abstract

Ultraviolet radiation 254nm is highly inimical to microorganisms to the extent that substances which by themselves are mildly antagonistic offered no synergistic advantage when co jointly used with the radiation. The course of sterilization by radiation was markedly influenced by the bulk of material. UV radiation 350nm on the other hand showed two distinctly opposing elects: of a capacity to revitalize radiation-injured Organism, albeit to a small extent, and a distinctly lethal &led; of the two, the latter effect is predominant.
