Article: A person can be exposed to uranium (or its radioactive daughters, such as radon) by inhaling dust in air or by ingesting contaminated water and food. The amount of uranium in air is usually very small; however, people who work in factories that process phosphate fertilizers, live near government facilities that made or tested nuclear weapons, live or work near a modern battlefield where depleted uranium weapons have been used, or live or work near a coal-fired power plant, facilities that mine or process uranium ore, or enrich uranium for reactor fuel, may have increased exposure to uranium. Houses or structures that are over uranium deposits (either natural or man-made slag deposits) may have an increased incidence of exposure to radon gas. The Occupational Safety and Health Administration (OSHA) has set the permissible exposure limit for uranium exposure in the workplace as 0.25 mg/m3 over an 8-hour workday. The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) of 0.2 mg/m3 over an 8-hour workday and a short-term limit of 0.6 mg/m3. At levels of 10 mg/m3, uranium is immediately dangerous to life and health.

Artikel: En person kan utsättas för uran (eller dess radioaktiva döttrar, till exempel radon) genom att inandas damm i luft eller genom att inta förorenat vatten och mat. Mängden uran i luften är dock oftast mycket liten; människor som arbetar i fabriker som bearbetar fosfatgödsel, bor nära statliga anläggningar som tillverkat eller testat kärnvapen, bor eller arbetar nära ett modernt slagfält där vapen med utarmat uran har använts, eller bor eller arbetar nära ett koleldat kraftverk, anläggningar som bryter eller bearbetar uranmalm, eller anrikar uran för reaktorbränsle, kan ha ökat exponeringen för uran. Hus eller strukturer som är över uranfyndigheter (antingen naturliga eller konstgjorda slaggfyndigheter) kan ha en ökad förekomst av exponering för radongas. Arbetarskyddsverket (OSHA) har fastställt den tillåtna exponeringsgränsen för uranexponering på arbetsplatsen till 0,25 mg/m3 under en 8-timmars arbetsdag. Institutet för arbetarskydd (NIOSH) har fastställt en rekommenderad exponeringsgräns (REL) på 0,2 mg/m3 under en 8-timmars arbetsdag och en korttidsgräns på 0,6 mg/m3. Vid nivåer på 10 mg/m3 är uran omedelbart farligt för liv och hälsa. Svara nu på den här frågan: Vad är OSHA?
