Ultraviolet radiation albedo of natural surfaces

This article presents measurement results of intensity of solar UVA and UVB radiation, as well as UV radiation albedo from various surflaces. The intensity of albedo was measured from natural surfaces, such as: sand, grass., water., and snow. The paper also presents measurements of solar emitted UVA and UVB radiation intensity in the shadow. Ultraviolet radiation intensity and Surface albedo was measured using a handy UVA radiation radiometer UVA - 365HA, with spectral response of 320-390 nm and a handy UVB radiation radiometer PMA220 I with spectral response of 280-320 nm. The results Of measurements show that snow has the maximum albedo - from 50 to 60 per cent, sand - 10 per cent, and the minimum albedo is for grass - 2 or 3 per cent. The data of experimental measurements of UVA and UVB radiation in the shadow show that maximum reduction of intensity of UVA radiation tip to 80%, was at 1 p.m. in comparison with reduction of intensity of UVB radiation to 70% at 2 p.m.
