Radiometry is important in astronomy, especially radio astronomy, and plays a significant role in Earth remote sensing.
The measurement techniques categorized as radiometry in optics are called photometry in some astronomical applications, contrary to the optics usage of the term.
Learn about different types of radiometric dating, such as carbon dating.
Understand how decay and half life work to enable radiometric dating.
The use of radiometers to determine the temperature of objects and gasses by measuring radiation flux is called pyrometry.
Carbon-14 has two more neutrons than stable carbon, and thus has a mass that is greater by two.Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.Radiometry is a set of techniques for measuring electromagnetic radiation, including visible light.Radiometric techniques in optics characterize the distribution of the radiation's power in space, as opposed to photometric techniques, which characterize the light's interaction with the human eye.Radiometry is distinct from quantum techniques such as photon counting.
