Abstract The present paper proposed to use Gafchromic EBT3 films covered with 2, 4 and 6 polypropylene-film barriers for long-term monitoring of solar UV radiation. The usable range for the films with 2 barriers was from ∼4 to ∼40 Jcm −2 , that for the films with 4 barriers was from ∼20 to ∼200 Jcm −2 , and that for the films with 6 barriers was from ∼100 to ∼600 Jcm −2 . As such, using films with 4 and 6 barriers could extend the usable range up to 200 and 600 Jcm −2 , respectively, which would be useful for consecutive 4-d and 12-d UV exposure measurements, respectively (considering a possible maximum UV exposure of 50 Jcm −2 per day).
