  2. Solar irradiance - Wikipedia

    en.wikipedia.org/wiki/Solar_irradiance

    Global Map of Global Horizontal Radiation [5] Global Map of Direct Normal Radiation [5] There are several measured types of solar irradiance. Total solar irradiance (TSI) is a measure of the solar power over all wavelengths per unit area incident on the Earth's upper atmosphere. It is measured perpendicular to the incoming sunlight. [3]

  3. Radiometer - Wikipedia

    en.wikipedia.org/wiki/Radiometer

    A radiometer or roentgenometer is a device for measuring the radiant flux (power) of electromagnetic radiation. Generally, a radiometer is an infrared radiation detector or an ultraviolet detector. [1] Microwave radiometers operate in the microwave wavelengths. While the term radiometer can refer to any device that measures electromagnetic ...

  4. Irradiation - Wikipedia

    en.wikipedia.org/wiki/Irradiation

    Irradiation. Irradiation is the process by which an object is exposed to radiation. An irradiator is a device used to expose an object to radiation, notably gamma radiation, for a variety of purposes. [1] Irradiators may be used for sterilizing medical and pharmaceutical supplies, preserving foodstuffs, alteration of gemstone colors, studying ...

  5. Sunlight - Wikipedia

    en.wikipedia.org/wiki/Sunlight

    Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is scattered and filtered through Earth's atmosphere as daylight when the Sun is above the horizon.

    Then, two years later, the dog parents brought all those toys back into the rotation. " Three dogs had all 12, another had 11 toys, and one dog had only five toys as some had been misplaced," The ...

  7. Radiation damage - Wikipedia

    en.wikipedia.org/wiki/Radiation_damage

    Radiation damage is the effect of ionizing radiation on physical objects including non-living structural materials. It can be either detrimental or beneficial for materials. Radiobiology is the study of the action of ionizing radiation on living things, including the health effects of radiation in humans.

  8. Irradiance - Wikipedia

    en.wikipedia.org/wiki/Irradiance

    Irradiance. In radiometry, irradiance is the radiant flux received by a surface per unit area. The SI unit of irradiance is the watt per square metre (W⋅m −2). The CGS unit erg per square centimetre per second (erg⋅cm −2 ⋅s −1) is often used in astronomy. Irradiance is often called intensity, but this term is avoided in radiometry ...

  9. Photostationary state - Wikipedia

    en.wikipedia.org/wiki/Photostationary_state

    The position of the photostationary state is primarily a function of the irradiation parameters, the absorbance spectra of the chemical species, and the quantum yields of the reactions. The photostationary state can be very different from the composition of a mixture at thermodynamic equilibrium. As a consequence, photochemistry can be used to ...
