Abstract
During the Coronavirus pandemic, the world counted on conventional sanitizing products that involved unsafe toxic chemicals. Ultraviolet Germicidal Irradiation or ultraviolet disinfection is introduced in many sanitizing applications, as it splits the DNA/RNA, forcing microorganisms unable to spread. For that, ultraviolet disinfection technology is presented in this project to replace the old nonenvironmental practices. Far-ultraviolet type C is a small part of the ultraviolet spectrum, with wavelengths from 207 nm to 222 nm proven effective against micrograms. This project aims to apply far-ultraviolet technology to design an easily used, reliable, and optimized system to control and monitor the sanitizing operation. Moreover, this project design combines two different sanitizing modes intended to serve the need of a dental clinic's daily sanitizing technique. The first mode is intended to sanitize the dentist's tools connected to a monitoring system that shows the ultraviolet type C intensity and the received dosage. The second mode is for the surfaces and handlers in the clinic; the sanitizing handheld will be attached to a distance identification system that guides the user to apply the sanitizing operation at the proper distance. Furthermore, this project will determine the disinfection parameters (dosage, intensity, exposure time, wavelength, and distance) according to the used far-ultraviolet source and the prototype design.
