Section 2
SECTION 2: Hazards identification
EMERGENCY OVERVIEW Thorium oxide filament coating is an irritant for eyes and skin. Thorium compounds are mildly radioactive: it is possible that long term cumulative effects of thorium compounds in the body may increase the risk of cancer. For short and long term exposure effects see Section 11 Toxicological data. Eye Effects: Toxic by contact if eye is cut or abraded. Thorium oxide is an irritant. Skin Effects: Toxic by skin contact if skin is cut or abraded. Thorium oxide is an irritant and can cause dermatitis after repeated contact. Ingestion/Oral Effects: Thorium nitrate and thorium oxide are very toxic if ingested. Once deposited in the body, thorium remains for a long period of time and may increase the risk of induced cancer in the tissues where it is deposited. Inhalation Effects: Thorium nitrate is very toxic if inhaled. May be a respiratory irritant. Inhaled thorium oxide tends to remain in the lungs and may increase the risk of cancer due to alpha and gamma radiation emission.
