  • Description: An odorless to chalky smelling orange-yellow sand-like solid in its pure crystalline form.
  • Molecular Weight: 436.02
  • Melting Point, ℃: Decomposes at 400℃
  • Density: 5.6


General advice:

  • Consult a physician.
  • Show this safety data sheet to the doctor in attendance.
  • Move out of dangerous area.


  • Protect from physical damage.
  • Store at in cool, dry place.
  • Protect personnel from radiation emanation if present.
  • Separate from other readily oxidizable or combustible materials.


  • All chemicals should be considered hazardous.
  • Avoid direct physical contact.
  • Use appropriate, approved safety equipment.
  • Untrained individuals should not handle this chemical or its container.
  • Handling should occur in a chemical fume hood.

Protection: Approved dust respirator self-contained breathing apparatus; goggles or face shield; protective clothing.

Respirators: Use NIOSH/MSHA approved respirator appropriate for exposure of concern.

Small spills and leaks:

  • Evacuate area and ventilate.
  • Wear protective equipment.
  • If required, use an inert absorbent.
  • Sweep up and place in an appropriate container for disposal.
  • Wash contaminated surfaces.


  • Can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers).
  • Can react violently with active metals, cyanides, esters, and thiocyanates.


Extinguishing Media

Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide.

Special hazards arising from the substance or mixture: Carbon oxides, Uranium oxides.

Advice for firefighters:

  • Wear self-contained breathing apparatus for firefighting if necessary.
  • Contain runoff.


Exposure Limits

OSHA: PEL (8 h TWA): 0.05 mg

Exposure Effects: Supra lethal radiation doses may result in headache, acute brain syndrome, alterations in mental status including coma, and (rarely) seizures within minutes of exposure. Prenatal ionizing radiation exposure may cause
congenital anomalies, mental retardation, and an increased incidence of seizures.

Ingestion: Gastrointestinal syndrome (nausea/vomiting) commonly occurs after doses of 9 to 20 gy and may occur following doses as low as 5 gy. Initial vomiting is followed by persistent diarrhea, which may be bloody.

Inhalation: Pulmonary radiation injury may result in radiation pneumonitis and radiation pulmonary fibrosis.

Skin: Thermonuclear burns may occur. If erythema is produced by a penetrating radiation, serious systemic injury is certain.

First Aid


  • Seek medical attention.
  • If the patient is drowsy or unconscious, do not give anything by mouth. Place the patient on the left side with the head down.
  • Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting.
  • If possible, do not leave patient unattended.


  • Monitoring exposed patients for contamination and decontamination procedures should be started.
  • All personnel involved in handling patients should wear disposable protective clothing.
  • The patient should be completely undressed and given a soap and water bath or shower (if the patient’s
    condition permits and if the facility exists).
  • Acute inhalation of radionuclides presents some difficult problems.


  • Remove contaminated clothing.
  • Wash exposed area with soap and water.
  • If symptoms persist, seek medical attention.
  • Launder clothing before reuse.


  • If symptoms develop, immediately move individual away from exposure and into fresh air.
  • Flush eyes gently with water for at least 15 minutes while holding eyelids apart.
  • Seek immediate medical attention.



The U.S. Department of Transportation (D.O.T.) Code of Federal Regulations (49 CFR Parts 100-185), the International Air Transportation Association (IATA), International Civil Aviation Organization (ICAO), and International Maritime Organization (IMDG) are all factored into the classification and transport of material.

Classification of substances with multiple hazards must be determined in accordance with the criteria presented in regulations mentioned above. Due to the various quantities/combinations of materials being shipped at one time, the information above must be determined based on the characteristics of the specific shipment.


Other Adverse Effects

  • An environmental hazard cannot be excluded in the event of unprofessional handling or disposal.
  • Toxic to aquatic life with long lasting effect


Uranium like other actinides readily forms a dioxide uranyl core (UO2). In the environment, this uranyl core readily
complexes with carbonate to form charged complexes. Although uranium forms insoluble solids or adsorbs to mineral surfaces at alkaline pH it is these soluble carbonate complexes that increase its solubility, availability, and mobility with low affinities to soil. Uranium(VI) generally forms a pH-dependent suite of uranyl-carbonate complexes in ground water solutions:

  • UO2(OH)2+1
  • UO2(CO3)2-2
  • UO2(CO3)3-4
  • UO2(CO3)(OH)3-1

A common method for concentrating uranium from a solution uses solutions of uranyl carbonates which are passed through a resin bed where the complex ions are transferred to the resin by ion exchange with a negative ion-like chloride. After buildup of the uranium complex on the resin, the uranium is eluted with a salt solution and the uranium is precipitated in another process.
