In measuring the output of light from the human skin, we estimated the total photon rates to be of the order of 170-600 photons/s/cm2, depending on anatomical location. The light was strongest at the red end of the spectrum, but fell below detectable levels in the ultraviolet. Significant variations were observed between individuals in both photon rate and spectral profile. The photon rate also varied significantly with time for a single individual. The possible source of this light and its significance are discussed.
This research output has an Altmetric Attention Score of 11. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 22 October 2026.
All research outputs
#4,296,312
of 34,638,994 outputs
Outputs from Acupuncture & Electro-Therapeutics Research
#13
of 183 outputs
Outputs of similar age
#3,633
of 83,452 outputs
Outputs of similar age from Acupuncture & Electro-Therapeutics Research
#2
of 5 outputs
Altmetric has tracked 34,638,994 research outputs across all sources so far. Compared to these this one has done well and is in the 87th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 183 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.7. This one has done particularly well, scoring higher than 92% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 83,452 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 95% of its contemporaries.
We're also able to compare this research output to 5 others from the same source and published within six weeks on either side of this one. This one has scored higher than 3 of them.
