  • Protect from physical damage.
  • Store in a 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: Use an approved dust respirator or self-contained breathing apparatus, goggles or face shields, and protective clothing.

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

Smalls spills and leaks:

  • Evacuate the 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.
  • Prevent further leakage or spillage if safe to do so.
  • Pick up and arrange disposal without creating dust.
  • Avoid breathing dust, vapors, mist, or gas.


  • 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.


  • Use appropriate media to suppress fire exposure.
  • Contain runoff.

Extinguishing Media

Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemicals, 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.


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. Serious systemic injury is certain if erythema is produced by penetrating radiation.

Exposure Controls

At any detectable concentration:  Any self-contained breathing apparatus with a full facepiece operated in a pressure-demand or other positive-pressure mode.

Any supplied-air respirator with a full facepiece operated in a pressure-demand or other positive-pressure mode or other positive-pressure mode with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure mode.

Escape – any air-purifying, full-facepiece respirator with a high-efficiency particulate filler.

Any appropriate escape-type, self-contained breathing apparatus.

Firefighting and Other Immediately Dangerous to Life or Health Conditions

Use any self-contained breathing apparatus with a full facepiece respirator and a high-efficiency particulate filter.

Use any supplied-air respirator with a full facepiece operated in a pressure-demand or other positive-pressure mode or other positive-pressure modes with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure modes.


General advice:

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


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


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



Uranium potassium carbonate

Systematic name: Uranium potassium carbonate

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

Proper Shipping Name:

Hazard Class:

UN/ID Number:                                          To be determined on a case-by-case basis.

Special Information:

Packing Group:

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


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


Like other actinides, Uranium 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 the soil. Uranium(VI) generally forms a pH-dependent suite of uranyl-carbonate complexes in groundwater 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 the buildup of the uranium complex on the resin, the uranium is eluted with a salt solution and the uranium is precipitated in another process.
