Ultraviolet Radiation Sterilization

ultraviolet-radiation-sterilization

Ultraviolet radiation disrupts the chemical bonds which hold bacteria and viruses together. Ultraviolet radiation is able to kill the cell and ensures whatever material is exposed afterwards becomes sterile. The longer an organism is exposed to ultraviolet radiation, the less likely it is to have any microbes alive upon it. Hospitals and various industries utilize this method of sterilization to ensure their equipment and environment is as free of microorganisms as possible

The Bubonic Plague

Black-Plague

The Bubonic Plague killed off approximately 66% of Europe during the 1350’s with the exception of Milan, Italy and Kraków, Poland. This was due to the people of Milan understanding that quarantining the city was a necessary requirement to help aide in the cessation of disease proliferation. Quarantining was performed despite physicians not properly and/or fully understanding the mechanics of viral and bacterial infection. The citizens of Milan also burned down the home of any person or family suspected of having recently contracted the Black Plague. Kraków was a prominent refuge for people of Jewish descent, as Jewish people were used as scapegoats as to the reason why the Black Plague occurred in Europe in the first place. Due to the fact that Jews frequently bathed as it was not in conflict with their religious beliefs, unlike most others in Europe, the Black Plague was barred from having as great of an effect as it did across the rest of Europe. Milan and Kraków were left virtually unscathed with most of their populations surviving the catastrophic epidemic
