Ultraviolet (UV) radiation is ionizing but it is not penetrating, so it can be shielded by thin opaque layers such as sunscreen, clothing, and protective eyewear.
Voters had their fingers marked with an invisible ink that showed up under Ultraviolet light to detect attempts to vote twice.
Also, most of the score that Klaus Badelt composed for the film were used as the score of the show.
Artificial UVB/UVA light and vitamin supplements must be balanced with proper food and nutrition, UVB light is required for calcium absorption from the gut.

The rust fungus Puccinia monoica infects the plant leading to pseudoflowers, which mimic those of yellow, early spring wildflowers (e.g. buttercups), not only in visible light but also in ultraviolet.
Even if the product can not be isolated, other analytical techniques can be performed on the solution including NMR, EPR, UV-Vis, FTIR, among others techniques depending on the specific situation.
Mechanisms which break polymer chains are familiar to biologists because of their effect on DNA: ionizing radiation (most commonly ultraviolet light), free radicals, and oxidizers such as oxygen, ozone, and chlorine.
In 1904, Moritz von Rohr and August Köhler at Carl Zeiss constructed the first ultraviolet microscope.
During the mission the crew successfully deployed the Galileo spacecraft, starting its journey to explore Jupiter, operated the Shuttle Solar Backscatter Ultraviolet Instrument (SSBUV) to map atmospheric ozone, and performed numerous secondary experiments involving radiation measurements, polymer morphology, lightning research, microgravity effects on plants, and a student experiment on ice crystal growth in space.
It was also not as common as the earlier Steenbock process, in which milk was exposed directly to ultraviolet light, which converts milk's natural 7-dehydrocholesterol content to vitamin D3.
-- Excimer laser light is typically absorbed within under a millionth of a meter (nanometer) of tissue. * * *a millionth of a meter is a micrometer, a billionth of a meter is a nanometer. Which one is it?* * *-->In 1980–1983, Rangaswamy Srinivasan, Samuel Blum and James Wynne at IBM’s T. J. Watson Research Center observed the effect of the ultraviolet excimer laser on biological materials.
The principal investigator and chief engineer of the Far Ultraviolet Camera/Spectrograph was Dr. George Robert Carruthers, who was working at the US Naval Research Lab.

Later on in 1986, one of Carruthers' inventions captured an ultraviolet image of Halley's Comet.
His invention of an Ultraviolet "Vitamin D" lamp for irradiating milk was sold to General Foods for $300,000.
UV-Vis Spectrometer (UVS), that will measure both the dust and exosphere.
Markarian 231 (UGC 8058) is a Type-1 Seyfert galaxy that was discovered in 1969 as part of a search of galaxies with strong ultraviolet radiation.
During the mission crew members successfully deployed the Galileo spacecraft on its journey to explore Jupiter, operated the Shuttle Solar Backscatter Ultraviolet Instrument (SSBUV) to map atmospheric ozone, and performed numerous secondary experiments involving radiation measurements, polymer morphology, lightning research, microgravity effects on plants, and a student experiment on ice crystal growth in space.
Recent years, ZnO nanorods have been intensely used to fabricate nano-scale electronic devices, including field effect transistor, ultraviolet photodetector, Schottky diode, and ultra-bright light-emitting diode (LED).
The Nike laser at the United States Naval Research Laboratory in Washington, DC is a 56 beam, 4-5 kJ per pulse electron beam pumped krypton fluoride excimer laser which operates in the ultraviolet at 248 nm with pulsewidths of a few nanoseconds.
His thesis focused on the ultraviolet (UV) emissions from the Sun observed with instruments on sounding rockets and the space shuttle Challenger.
The term refers to various techniques, depending on whether the ionization energy is provided by an X-ray photon, an EUV photon, or an ultraviolet photon.
The skin condition is a cutaneous phototoxic inflammatory eruption resulting from contact with light-sensitizing botanical substances—particularly from the plant families Umbelliferae, Rutaceae, Moraceae, and Leguminosae—and ultraviolet light, typically from sun exposure.
It was proposed the instruments would be a visible camera, an infrared spectrometer, an ultraviolet spectrometer, and a radio transmitter to send its findings back to Earth.
Polarization spectroscopy comprises a set of spectroscopic techniques based on polarization properties of light (not necessarily visible one; UV, X-ray, infrared, or in any other frequency range of the electromagnetic radiation).
The town has been certified as a climate resort by government decree (H.G. 226/1992) due to the strongly ionized air rich in ultraviolet radiation and the low atmospheric pressure.
Both the aluminum-based quantum clock and the mercury-based atomic clock keep track of time from the ion vibration at an optical frequency by using a UV laser, that is 100,000 times higher than the microwave frequencies used in NIST-F1 and other similar time standards around the world.
The United States Naval Research Laboratory (NRL) has built five of these ultraviolet spectrographs for the United States Air Force (USAF) Defense Meteorological Satellite Program (DMSP) block of 5D3 satellites.
In 1998, The Chemical Brothers released a DJ mix CD called Brothers Gonna Work It Out, which featured a song by a San Francisco techno / breakbeat band named The Ultraviolet Catastrophe.

The term "ultraviolet catastrophe" was first used in 1911 by Paul Ehrenfest, although the concept goes back to 1900 with the first derivation of the dependence of the Rayleigh–Jeans law; the word "ultraviolet" refers to the fact that the problem appears in the short wavelength region of the electromagnetic spectrum.
The concept is based on the ability of ultraviolet light to kill infectious agents by disrupting their DNA.
In the early 19th century, the concept of the visible spectrum became more definite, as light outside the visible range was discovered and characterized by William Herschel (infrared) and Johann Wilhelm Ritter (ultraviolet), Thomas Young, Thomas Johann Seebeck, and others.
The "sky lanterns" are made of ultraviolet-resistant PTFE fiber nets, supported by painted galvanized steel rings.
He contributed to the Mariner 5 flyby of Venus in 1967, and the Mariner 6 and 7 flybys of Mars in 1969, as well as heading the ultraviolet spectrometer experiment on Apollo 17 in 1972 - the missions using ultraviolet spectrometers designed by Fastie in 1952.
Woodward's rules, named after Robert Burns Woodward and also known as Woodward–Fieser rules (for Louis Fieser) are several sets of empirically derived rules which attempt to predict the wavelength of the absorption maximum (λmax) in an ultraviolet–visible spectrum of a given compound.
