· 1 Cal/cm2of incident energy will raise 1 gram of water 1 degree Celsius. This is important to us because the human adult body contains roughly 57-60% water. When we are exposed to incident energy the water in our tissues heats up and we can incur a burn even if our clothing is not ignited. The onset of second degree burn can occur at 1.2 Cal/cm2.
