Actionspectrum 4: DNA Damage

Full Spectrum

Action spectrum for DNA damage

Spectrum suggested by:
R. B. Setlow,
"The wavelengths in sunlight effective in producing skin cancer: a theoretical analysis", Proc. Nat. Acad. Sci., USA, 71 , No. 9,
pp. 3363-3366, 1974

The parameterization used is that suggested by
G. Bernhard and G. Seckmeyer,
"Measurements of spectral solar UV irradiance in tropical Australia",
Journal of Geophysical Research, Vol 102, No. D7, 8719-8730, 1997.
A = 1 / 0.0326 * exp(13.82 * ( 1 / (1+exp(( W-310) / 9 ))-1))

The action spectrum suggested by Setlow describes the relative biological effect per quantum. For the parameterization given above and the values below it was assumed that the the action spectrum describes the effect per energy unit.
