J. Diaz et al., MEASUREMENT OF THE SOLAR UV-RADIATION AT THE EARTH SURFACE USING A DETECTOR TUNABLE IN THE 230 TO 430 NM RANGE, Physica status solidi. a, Applied research, 139(2), 1993, pp. 549-554
The solar ultraviolet radiation at the earth surface is measured by us
ing a detector based on Eu2+-doped NaCl. The device response, which ex
tends from 230 to 430 nm, matches the active excitation regions of ult
raviolet light in many environmental and biological phenomena. An appl
ication is presented, where the ultraviolet solar intensity at differe
nt latitudes is measured at wavelengths with a sizable (lambda = 312 n
m) or without (lambda = 365 nm) ozone absorption.
