Uranyl Sodium Carbonate
|Description||An odorless to chalky smelling orange-yellow sand-like solid in its
pure crystalline form.
|Registry Numbers and Inventories.|
|NIH PubChem CID|
|Formula mass||542 MW|
|Hazards and Protection.|
|Storage||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.
|Handling||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
|Small spills/leaks||Evacuate area and ventilate. Wear protective equipment. If required,
use an inert absrobent. Sweep up and place in an appropriate container for
disposal. Wash contaminated surfaces.
|Incompatibilities||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.
|Fire fighting||Use appropriate media to suppress exposure fire. Contain
|Exposure limit(s)||OSHA: PEL (8 h TWA): 0.05 mg|
|Exposure effects||Supralethal 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
|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.
|Ingestion||Seek medical attention. If individual is drowsy or unconscious, do
not give anything by mouth; place individual 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
|Inhalation||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.
|Skin||Remove contaminated clothing. Wash exposed area with soap and water.
If symptoms persist, seek medical attention. Launder clothing before reuse.
|Eyes||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.

Rutherfordine is a mineral containing almost pure
uranium carbonate (UO2CO3). It was discovered in 1906 and
is named after Ernest Rutherford. It is found primarily in the Morogoro Region
of Tanzania in Africa. It has been reported in Zaire and the Northern Territory
of Australia. It appears as brownish, brownish yellow, white, light brown
orange, or light yellow fluorescent encrustations. It is a secondary alteration
product from uraninite. It crystallizes in the orthorhombic system in
translucent lathlike, elongated, commonly radiating in fibrous masses,
inpulverulent, earthy to very fine-grained dense masses. It has a specific
gravity of 5.7 and exhibits two directions of cleavage. It is also known as
Rutherfordine forms under acidic to neutral pH and is the
only known mineral that contains only uranyl and carbonate. It was discovered by
Marckwald (1906) and described as a mineral species by Frondel and Meyrowitz
(1956). The structure of rutherfordine was provided by Christ and Clark (1955)
and refined by Finch et al.(1999). As a carbonate, rutherfordine will react with
acids, liberating carbon dioxide.
