Hello, I am trying to figure out how much the human skin temperature would increase when the skin is illuminated by radiation of a certain intensity (W/m^2). We can assume that the skin has an emissivity and absorptivity both equal to 1. For instance, imagine the skin illuminated by the sun (I= 1000W/m^2) or by another radiation source.. We know the initial temperature of the skin and the intensity of the incident radiation. What equation would I use? Thanks!
