Standard erythema dose
WebbThe UV dose is computed for three different action spectra, i.e. for three different health effects: erythema (same as UV index), vitamin-D production in the skin and DNA-damage. The following graph shows the three action spectra including in v2.x of the TEMIS UV data products; for references see the end if this page. As the graph shows, the ...
