WebNotes. Boundary Energy can be set at 5.0 J/cm 2 for bare skin or at the rating of any proposed PPE.; The limit of 5.0 J/cm 2 is that at which a person is likely to receive second degree burns.; To convert J/cm2 to cal/cm2 multiply by 0.239 The solar constant (GSC) is a flux density measuring mean solar electromagnetic radiation (total solar irradiance) per unit area. It is measured on a surface perpendicular to the rays, one astronomical unit (au) from the Sun (roughly the distance from the Sun to the Earth). The solar constant includes radiation over the entire electromagnetic spectrum. It is measured by satellite as being 1.361 kilowatts per square meter (kW/m ) at solar minimum (the time in the 11-y…
