Radiometric Unit Symbol Definition Radiant flux Φ The total optical power emitted from a source. Irradiance E The flux per unit area striking a surface. Intensity I The flux per unit solid angle from ...

Measurements like this can also be used to gauge the luminous flux (in lumens) and associate with the response of the human eye. Spectral irradiance, spectral radiant intensity and spectral radiance ...

The maximum neutrino flux in the sample in their experiments was several times greater than the flux of neutrinos from the sun. The researchers followed the gamma-ray emission rate of each source ...

The primary uncertainty in lunar impact flux arises from the mismatch between radiometric ages and model ages predicted by crater chronology. This uncertainty mainly stems from the imperfect ...

That makes radioactive isotopes wonderful clocks. Today, radiometric dating spans the ages, from recent times to the birth of our solar system. Carbon-14 dating is most suited to something that ...

Radiometric calibration and optical analysis of in-flight satellite-based imagers is generally achieved using on-board systems and by vicarious observation of celestial objects and earth-based ...

By measuring the ratio of lead to uranium in a rock sample, its age can be determined. Using this technique, called radiometric dating, scientists are able to "see" back in time.
