  • The Solar Backscatter Ultraviolet Radiometer, or SBUV/2, is a series of operational remote sensors on NOAA weather satellites in Sun-synchronous orbits which have been providing global measurements of stratospheric total ozone, as well as ozone profiles, since March 1985. (wikipedia.org)
  • protection
  • Moreover, there are people who benevolently expose their skin to the powerful sun rays without any protection, thus damaging their skin willingly. (paulussantoso.com)
  • It was founded in 1928 by at the second International Congress of Radiology in Stockholm, Sweden and was then called the International X-ray and Radium Protection Committee (IXRPC). (wikipedia.org)
  • A year after Röntgen's discovery of X-rays, the American engineer Wolfram Fuchs (1896) gave what is probably the first protection advice, but many early users of X-rays were initially unaware of the hazards and protection was rudimentary or non-existent. (wikipedia.org)
  • and the 'International X-ray and Radium Protection Committee' (IXRPC) was formed. (wikipedia.org)
  • present
  • Ultraviolet rays are present 24hrs a day, rain snow or shine, has anyone come up with a way to use this abundent energy. (madsci.org)
  • The present invention relates to a glass composition which has a high ultraviolet ray absorbing ability and a relatively high luminous transmittance and which has the same brown color as current colored plate and float glass for buildings and vehicles. (google.com)
  • burns
  • Thus, people with darker skin have more melanin in the composition of the skin, thus are less prone to skin lesions or burns caused by the sun rays. (paulussantoso.com)
  • On the other hand, people with lighter skin lack the necessary amount of melanin which can effectively combat the sun rays, thus are more susceptible to burns and skin damages cause by sun. (paulussantoso.com)
  • A report by Dr. H.D. Hawks, a graduate of Columbia College, of his suffering severe hand and chest burns in an x-ray demonstration, was the first of many other reports in Electrical Review. (wikipedia.org)
  • glass
  • Ultraviolet ray absorbent colored glass for buildings and vehicles, which consists essentially of from 65 to 75 wt % of SiO2, from 0.1 to 5.0 wt % of Al2 O3 , from 10 to 18 wt % of Na2 O, from 0 to 5 wt % of K2 O, from 5 to 15 wt % of CaO, from 1 to 6 wt % of MgO, from 0.05 to 1.0 wt % of SO3, from 0.08. (google.com)

  • Further, brown-colored glass has had a problem that it is likely to be discolored by ultraviolet rays. (google.com)
  • form
  • Photoretinitis is another form that can occur due to infra-red rays (eclipse burn of retina). (wikipedia.org)
  • star
  • Its companion would be a low-mass star of spectral classification K or M that would complete an orbit around the Wolf-Rayet star each 5.13 days, being the progenitor of a low-mass X-ray binary system. (wikipedia.org)
  • Year
  • In February of that year, Professor Daniel and Dr. Dudley of Vanderbilt University performed an experiment involving x-raying Dudley's head that resulted in his hair loss. (wikipedia.org)
