AUTUNITE FACTS

&

 FREQUENTLY ASKED QUESTIONS


 

What causes a mineral to be Fluorescent when exposed to Uv light?

   Briefly, when an atom of a certain substance receives Uv light an electrons of the atom reacts to the energy by moving away from the nucleus. In doing so a gap is created in the electrons around the nucleus. To maintain balance within the atom another electron must give up some of it's energy and move in to occupy the empty orbit. It is this energy that the electron gives up that we see as visible light. Some minerals react to only long wave Uv, some to only short wave Uv and a few, such as Autunite will react to any type of Ultra Violet light.

   One of the best books describing Fluorescence, "The Story of Fluorescence", is produced by "RayTech Industries" who manufactures some of the best Ultra Violet lamps on the market. This $3.00 book describes with good detail the cause of fluorescence, the application & uses of fluorescence and 22 pages of fluorescent mineral identifications. 

 

 

Is Autunite dangerous?

   Autunite is a naturally occurring Uranium and is radioactive. The amount of radiation produced by a specimen will vary depending on how much actual Autunite is in/on a specimen. Usually Autunite will be found as crystals deposited on the exterior of a matrix rock which is usually Granite. The Autunite will be a very small amount compared to mass of the entire specimen. 

   Being radioactive it is wise to treat your specimen with the same respect you  would anything that has the potential to cause harm. By practicing the same precautions you would normally use  with paint or household chemicals you should have no trouble.  Please read our Autunite Safety Guidelines.

There is a lot of misleading information on the internet about Autunite and it's radioactivity.

 For the truth about radiation from Autunite please read what the Health Physics Society says about the safety of our Autunite.

 

 

Will Autunite change over time?

   Yes, Autunite contains water in it's chemistry and depending on humidity, temperature and time, some of this water will evaporate changing the  Autunite to Meta-Autunite. This process is very slow and takes many years. The fluorescent, radiation and visual properties are unchanged by this conversion. A few specimens will eventually loose enough water that they begin to crumble while other specimens will remain solid. 

 

There are two areas that this change pertains to:

1. Chemically the process is simple. The Autunite looses water and is converted to Meta-Autunite. Slowly introducing water to the Meta-Autunite will convert it back to the chemistry of Autunite. The conversion process is reversible, but keep reading.

 

2. When Autunite dehydrates and becomes meta-Autunite there may be shrinkage within the crystals. This causes  microscopic cracks in the individual crystals. These microscopic cracks can lead to the crystals chipping or splitting depending on their environment. Introducing water will re-establish the chemical formula but will not heal these microscopic cracks. In fact, if water is introduced to a very dry specimen the absorption of that water will cause the crystals to swell up and separate from the other crystals and the matrix. This will cause a specimen to crumble. 

 

The best way to preserve your specimen is through proper storage. Storage is best in a constant cool temperature. Avoid direct sun light. If the specimen is dry keep it that way. If the specimen is wet keep it that way. It is not recommended to re-hydrate a dry specimen. Store all radioactive specimens in a container so that any particles that chip off will be contained.

 

Two very good sources of information about Autunite/Meta-Autunite, and reversing the process can be found at these sites Mineral Galleries and Uranium Minerals. 

 

      Another method to preserve a specimen is to coat it with a clear, no luster, acrylic spray. This does not effect the looks of the specimen but will effect the Alpha radiation and the reaction Short Wave Uv.

   Just remember, the process of going from Autunite to Meta-Autunite simply involves the loss of water. Evaporation can be slowed, and even stopped, by controlling temperature, humidity and free contact with air.

    

 

 

Will Autunite dissolve in water.

Yes, but it takes hundreds to thousands of years depending on the properties of the water. Water with a high acidity will dissolve Autunite much faster than pure water.

 

 

Autunite is used to make nuclear fuel/bombs, will Autunite heat up or explode.

No, The radiation in natural Uranium/Autunite is very low. To be able to be reactor material or bomb 

material takes super refining using very expensive equipment and tons of Uranium/Autunite ore.

 

 

Will items close to my specimen become radioactive?

No. The radiation from the specimen will not cause any other substance to become radioactive. 

The same as your microwave oven only heats your food and doesn't cause your food  to be a microwave producer.

 

 

What are the properties of our Autunite?

Autunite has the chemical formula "Ca(UO2)2(PO4)2-10H2O" and is known as Hydrated Calcium Uranyl Phosphate.

Our Autunite produces 35% Alpha, 62% Beta and 3% Gamma radiation.

XRD shows it contains PB-214, PB-211, BI-214, BI-211, BI-206, RN-219, RA-223, TH-227, TH-231, TH-234, U-235, U-238, TL-208, NP-237 and other minor elements.

 

 

What are the Legal issues concerning the possession of Autunite?

All radioactive material is governed by Federal Law. Natural Uranium is exempt from the Federal restrictions. You may posses it, transfer it to other people and sell it PROVIDED you do not attempt to process it. The law governing possession of Uranium ore can be found at  10 CFR 40.13 (b)

There are other laws that govern the transportation of radioactive material including Uranium. These laws vary from one shipping company to another. The United States Post Office rules may be found in their Publication 52.
