# 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 # Figure 1 in the paper by Setlow was parameterized as follows.: # A = 10 ^ (13.04679 + (W * -0.047012)) for 286 <= W <2 90 # A = 10 ^ (20.75595 + (W * -0.073595)) for 290 <= W < 295 # A = 10 ^ (30.12706 + (W * -0.105362)) for 295 <= W < 300 # A = 10 ^ (42.94028 + (W * -0.148073)) for 300 <= W < 305 # A = 10 ^ (45.24538 + (W * -0.15563)) for 305 <= W < 340 # Resulting action spectrum was normalized to 1 at 300 nm. # This action spectrum is identical with the action spectrum defined in # the file SetlowBSI.txt, except of the normalization. # Dose rates derived with this action spectrum multipied with 3.2990E-02 # are idedntical with values labeled "Setlow" in the NSF UV database 3. # Integration range: 286 - 340 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. 286 1.2105E+01 287 1.0863E+01 288 9.7489E+00 289 8.7487E+00 290 7.8527E+00 291 6.6286E+00 292 5.5954E+00 293 4.7232E+00 294 3.9869E+00 295 3.3643E+00 296 2.6395E+00 297 2.0709E+00 298 1.6248E+00 299 1.2748E+00 300 1.0000E+00 301 7.1109E-01 302 5.0565E-01 303 3.5957E-01 304 2.5569E-01 305 1.8191E-01 306 1.2712E-01 307 8.8836E-02 308 6.2081E-02 309 4.3384E-02 310 3.0318E-02 311 2.1187E-02 312 1.4806E-02 313 1.0347E-02 314 7.2307E-03 315 5.0530E-03 316 3.5312E-03 317 2.4677E-03 318 1.7245E-03 319 1.2051E-03 320 8.4217E-04 321 5.8853E-04 322 4.1128E-04 323 2.8742E-04 324 2.0085E-04 325 1.4036E-04 326 9.8089E-05 327 6.8547E-05 328 4.7903E-05 329 3.3476E-05 330 2.3394E-05 331 1.6348E-05 332 1.1425E-05 333 7.9838E-06 334 5.5793E-06 335 3.8990E-06 336 2.7247E-06 337 1.9041E-06 338 1.3306E-06 339 9.2989E-07 340 6.4983E-07 340.01 1e-50
