I have found from various sources that the emissivity of human skin, irrespective of pigment, is close to unity. provide a biological explanation for the existence of a distinguishing pattern in human skin rejkctance. A monochromator was modified to measure the emissivity, ε(λ), of living tissue in the infrared region between 1 and 14 μm. I have been asked the following question; “What emissivity setting should I enter in my camera when carrying out a CM survey?”. emissivity in terms of the implied wavelength has to be taken into account, so a more precise method that explicitly takes into account wavelength is required.

Be aware, however, they are very specific to the material type, surface condition and, especially for metals, the temperature of the material. Human skin, with a value of 0.98, is 98% efficient at emitting thermal radiation while shiny aluminum, with a value of approximately 0.10, emits only 10% of the energy. Just be aware of reflections and you will usually be able to discern true thermal differences through comparison. When considering infrared radiation most shiny metals emit inefficiently.
