Power flux density

In the area of high-frequency radiation the power flux density is the measure of the strength of the radiation in the far field. Its measuring unit is Watt per square metre (W/m²). It characterises the energy flowing per time unit through an area vertical to the distribution direction of the radiation. If the high-frequency radiation is emitted by an antenna, the following applies: The greater the distance from the antenna the less the power flux density.

On April 25th, 2017 the operating duties and responsibilities for the Konrad repository were transferred to the BGE, the Federal Company for Radioactive Waste Disposal. Therefore this archival page of the Federal Office for Radiation Protection has not been updated since April 24th, 2017.
