Abstract | Ultraviolet (UV) radiation significantly influences many biological entities in the terrestrial biosphere. However, the amount of UV exposure can be affected by surfaces that reflect UV radiation. Knowledge about reflected UV radiation from surfaces in the built environment is limited, especially from vertical or other non-horizontal surfaces and the resulting effects of UV radiation reflection from these surfaces. The main aims of this research is comprised of (1) characterisation of UV radiation reflection from a variety of urban building materials in vertical positions, (2) quantification of the biological effect of UV reflection from simulated structures on a human and (3) establishing relationships between UV radiation measurement indicators and resulting biological effects. UV radiation reflection was investigated using spectral measurements made with portable spectrometers, and took into consideration factors that could influence the measurements including orientation, direction, solar zenith and azimuth angles and surface type. The biological effects due to reflection from vertical urban structures were investigated using dosimetry which enabled body site UV exposure analysis. Relationships from UV radiation reflection between different surface orientations (vertical, horizontal and inclined) were quantified. The UV Index was used to predict changes to UV exposure from certain vertical UV radiation reflective surfaces. |
