Power of emitted thermal radiation

Each body emits thermal radiation and its temperature decreases if it doesn’t absorb thermal radiation from another hot emitter. The following calculator determines  how much power can be emitted by a radiating body. The calculation depends on the body’s surface, temperature, emissivity and the surrounding temperature.
