    • Such sources usually attain brilliance by high current densities in small volumes. The total energy output may therefore be less than a greatly extended source of low steradiancy.1954, Alexander Hollaender, Radiation Biology: Ultraviolet and related radiations, page 123
    • The geometry of the cone θ and the irradiance at the image of the carbon block were used to determine the absolute steradiancy of the energy in the cone θ as a radiometer calibration value.1959, United States.
