**Mercury-quartz lamps in medicine: history, types, operating principle and application**
*It is known from the physiology of humans and living organisms that a lack of ultraviolet radiation contributes to diseases and other pathophysiological processes in the body. In order to overcome the problem of bacterial load, which poses a threat to human health and life, a new type of lamp was created that uses various disinfecting gases. In our article we will look at the mercury-quartz lamp, its history, varieties, components and principle of operation. We will also pay attention to the use of a quartz lamp for the treatment, prevention of diseases and disinfection of various surfaces.*
History of development
In the 19th century, German scientist Robert Bunge discovered the spectacular impact of quartz molecules under the influence of light pressure. A couple of years later, the German chemist Johann Wolfram Himerling announced the discovery of this phenomenon. Mercury taken in a pinch of a substance heated to a certain level of mercury type
