|Uranium (as U), Insoluble compounds
Synonyms: Uranium metal: Uranium I; Synonyms of other insoluble uranium compounds vary depending upon the specific compound.

OSHA Permissible Exposure Limit (PEL) for General Industry: 29 CFR 1910.1000 Z-1 Table -- 0.25 mg/m3 TWA
OSHA Permissible Exposure Limit (PEL) for Maritime: 29 CFR 1915.1000 Table Z-Shipyards -- 0.2 mg/m3 TWA
American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 0.2 mg/m3 TWA; 0.6 mg/m3 STEL; Appendix A1 - Confirmed Human Carcinogen
National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 0.2 mg/m3 TWA; 0.6 mg/m3 STEL; Appendix A - NIOSH Potential Occupational Carcinogens
NIOSH Immediately Dangerous To Life or Health Concentration (IDLH): 10 mg U/m3
Monitoring Methods used by OSHA
Potential symptoms: Increased urinary excretion of uranium from shrapnel in tissues; elevated prolactin level (upper end of normal range); In animals: lung, lymph node damage, dermatitis (carcinogenic
Health Effects: Cumulative kidney damage/lung accumulation (HE3)
Affected organs: Skin, kidneys, bone marrow, lymphatic system.
Notes: 1) Lower performance on computerized tests assessing performance efficiency was associated with elevated urine uranium levels in Gulf War veterans with shrapnel from munitions or armor made from depleted uranium (DU) in one study, but not confirmed in subsequent follow-up. 2) Rats implanted with DU pellets show marked accumulation of uranium in kidneys, bone and teeth, with lesser accumulation in liver, spleen, and brain. 3) Possible radiation-related effects likely due to decay products, especially radon.
