Processed or not uranium has some disadvantages:
1. Uranium is a possible polluting agent of the natural environment.
2. Uranium is a toxic and radioactive chemical element.
3. Uranium release radium and radon.
Uranium is extracted from mines and processed by chemical engineering techniques.
Actinium is more dangerous than uranium.
Before uranium is protactinium. After uranium is neptunium.
The radioactivity of natural uranium is not so important. The external irradiation is very low. But the internal irradiation is dangerous: alpha radiations from inhaled uranium, radium and radon (Ra and Rn released by decay from U) can destroy pulmonary alveoli and cause lung cancers. Also the ingestion is dangerous because soluble salts of uranium are toxic.
Nuclear fission of uranium-235 release fission energy.The fission energy is enormous compared to the energy obtained from fossil fuels.
As a metal uranium can by processed in any shape.
Uranium is extracted from mines and processed by chemical and metallurgical procedures.
Uranium is stored and processed in very strictly controlled area. The inventory of uranium is very severe.
Uranium is extracted from mines and processed by chemical engineering techniques.
Uranium is extracted from the earth by mining; after this it is processed by chemical/metallurgical procedures.
Processing of uranium can be dangerous only if the safety precautions are not observed or in the case of an unavoidable accident.
Actinium is more dangerous than uranium.
Disadvantages of uranium: 1. Uranium is a possible polluting agent of the natural environment. 2. Uranium is a toxic and a radioactive chemical element. 3. Uranium release radium and radon. 4. Radioactive wastes are dangerous and need to be isolated.
In the UK (Sellafield) and in France
Before uranium is protactinium. After uranium is neptunium.
See the link below for a MSDS of uranium tetrafluoride. Uranium tetrafluoride is dangerous: radioactive, toxic, corrosive; can affect eyes, skin and lungs (after inhalation).
The simple exposure to natural uranium is not so dangerous because the gamma radiation emitted is not so energetic and also it is auto-absorbed in the uranium material. The danger is to inhale or to ingest uranium compounds.
