The human body has a surface area of approximately 1.8 m2, a surface temperature of approximately 30°C, and a typical emissivity at infrared wavelengths of e = 0.97. If we make the approximation that all photons are emitted at the wavelength of peak intensity, how many photons per second does the body emit?
