Is there a radiometric term for the quantity (power emitted per unit volume per unit solid angle)?

Which volume are you referring to? That of the emitter?Khashishi said:Is there a radiometric term for the quantity (power emitted per unit volume per unit solid angle)?
How would one include the opacity of the medium, I wonder? The inner regions of a volume of gas would not necessarily have the same effect as the outer regions. Take the example of s Star, for instance. That's an extreme example but worth while thinking about.Khashishi said:emitter volume. For a gas or plasma.
Radiometric power emission refers to the amount of electromagnetic radiation, typically in the form of photons, that is emitted from a source. It is a measure of the total amount of energy radiated per unit time, and is typically measured in watts (W).
Radiometric power emission can be measured using a radiometer, which consists of a detector and a display unit. The detector captures the radiation emitted from a source and converts it into an electrical signal, which is then displayed on the unit in units of power.
The radiometric power emission of a source is dependent on its volume and the angle at which it is emitting radiation. Generally, the larger the volume of the source and the wider the angle of emission, the greater the radiometric power emission will be. This is because a larger volume and wider angle allow for more photons to be emitted.
Natural sources, such as the sun, are common sources of radiometric power emission. Artificial sources, such as light bulbs and lasers, also emit radiation and can be measured using radiometric techniques. Additionally, radioactive materials, such as those used in nuclear power plants, also emit radiation and have measurable radiometric power emissions.
Radiometric power emission is used in various scientific fields, such as astronomy, geology, and environmental science, to study and measure the properties of different sources. It can also be used to determine the composition and temperature of objects, as well as their distance from Earth. Additionally, radiometric power emission is used in medical imaging techniques, such as PET and CT scans, to detect and diagnose diseases.
