Investigation of Ultraviolet Radiation (UVR) in Benue State University, Makurdi, Benue State
Abstract
The study investigated the level of ultraviolet (UV) radiation in Benue State University, Makurdi. Since the greatest source of UV radiation reaching the earth surface is from the sun, we have investigated in detail the solar UV intensity in Benue State University. This was done through measurement of UV indices with the use of a broad band UV checker which infers the intensity of UV radiation. Typical values of ultraviolet indices between 7 and 13 were observed during clear sky hours in the solar noon hours of the day, meaning the UV radiation intensity was high. However,it was observed to be low/moderate between UVI of 1 and 6 when overcast occurred in the sky. But the intensities of UV radiation were observed to be constantly low/moderate from 6:00am-10:00am and 4:00pm-5:00pm times of the day.
