Noen sammenligninger av stråledata (mengde)...

Fra Wikipedia: (http://en.wikipedia.org/wiki/Sievert)

  • Living near a nuclear power station = less than 0.01 mSv/year[1]

  • Chest x-ray = 0.04 mSv[1]

  • Cosmic radiation (from sky) at sea level = 0.24 mSv/year[1]

  • Terrestrial radiation (from ground) = 0.28 mSv/year[1]

  • Mammogram = 0.30 mSv[1]

  • Natural radiation in the human body = 0.40 mSv/year[1]

  • Brain CT scan = 0.8–5 mSv[2]

  • Typical individual's natural background radiation: 2 mSv/year; 1.5 mSv/year for Australians, 3 mSv/year for Americans[3]

  • Radon in the average US home = 2 mSv/year[1]

  • Chest CT scan = 6–18 mSv[2]

  • Average American's total radiation exposure: 6.2 mSv/year[4]

  • New York-Tokyo flights for airline crew: 9mSv/year [3]

  • Smoking 1.5 packs/day = 13 mSv/year[5]

  • Gastrointestinal series X-ray investigation = 14 mSv[1]

  • Current average limit for nuclear workers: 20 mSv/year[3]

  • Background radiation in parts of Iran, India and Europe: 50 mSv/year[3]

  • Lowest clearly carcinogenic level: 100 mSv/year[3]

  • Criterion for relocation after Chernobyl disaster: 350 mSv/lifetime[3]

  • Highest recorded radiation outside Fukushima I Nuclear facility: 400 mSv per hour.
