www.who.intPower densities indoors were substantially less than power densities outdoors. When RF radiation from all sources (mobile phone, FM radio, TV, etc.) was taken into account the maximum power density at any site was less than 0.2% of the ICNIRP public exposure guidelines. [12, 13]
THE CHARACTERISTICS OF SUNLIGHT
www.eng.uc.edutotal power density, integrated over the spectrum, is referred to as the solar constant, with a generally accepted value (ASTM, 2000, 2003; Gueymard, 2004) of 1.3661kW/m 2 (1.5) Figure 1.6. The spectral power density of sunlight, outside the atmosphere (AM0) and at the earth’s surface (AM1.5), showing absorption from various atmospheric ...
