# 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 resulting action spectrum is 1 at 300 nm.

# Integration range: 256 - 370 nm

# 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.
