ABSTRACT
UV exposure cabinet is usually used for aging samples in various scientific fields such as chemistry, biology, historical objects, and coating scopes. In our case study, these kinds of cabinets were prepared to be used in the disinfection field. To have such an appropriate effect, there should be - as possible - a uniform exposing dose along with the whole irradiated area inside the cabinet. The proposed exposing cabinet consists of ten parallel UVC fluorescent lamps at the top and bottom of the cabinet's internal surface (group (A)). To enhance the irradiance and uniformity, two additional UVC lamps supported the UV lamps set (group (B)). The average values of irradiance and uniformity for the two groups, (A) and (B), were recorded. The results showed that the uniformity over the irradiated area improved by approximately 16.6%. When applying two collections of covid19 scan samples (coll (a) and coll (b)), the results showed that in the case of coll (b) with a group (B), the annihilation of the virus was succeeded almost along the irradiated area, which is much better than that what noticed in case of coll (a). Depending on the results, this paper discusses how the proposed enhancement technique used inside the exposing cabinets may help in the COVID-19 epidemic in disinfection purposes.
