A reference action spectrum
for ultraviolet induced erythema in human skin.
conversion factors that change erythemally weighted to previtamin [D.
In the following, we discuss common sources of error in UV radiation measurements, including out-of-band contributions to the signal, non-ideal geometric properties (non-ideal cosine response in the meters), and poor matching to a defined action spectrum
Moreover, the researchers found that the absorption spectrum of the smallest particles matched the action spectrum
of unsorted eumelanin.
Because knowledge about the action spectrum
for the induction of melanoma is limited, a risk analysis for this condition could not be conducted.
The action spectrum
for plankton death is similar to that for sunburning in humans, so the program can indicate the killing UV flux with and without the ozone hole.
Photopic detectors have a wide bandwidth and spectral response that closely follows the CIE photopic action spectrum
for melatonin regulation in humans: evidence for a novel arcadian photoreceptor.
The mechanism of skin injury has been closely co-related to the phenomenon that the action spectrum
for UVB erythema has been found to be close to the absorption spectrum for DNA after adjusting for the absorbance of incident energy by the stratum corneum.
So he and Van der Leun fine-tuned data on UV's skin carcinogenicity -- its action spectrum
-- in this mouse to account for the longer path UV rays must traverse through human skin.
