What were the two difficulties associated with the extraction of uranium?
The problems are:- radioactivity and toxicity of uranium- release of radon- generally low concentration of uranium in rocks- possible contamination of the environment
Which element exhibit radioactivity?
Several examples are uranium, thorium, radon, actinium, protactinium, plutonium, americium, etc.
A noble gas that is produced when radium undergoes radioactivity decay?
Radon is the noble gas generated when radium decays through radioactivity. It is colorless, odorless, and tasteless, making it difficult to detect without proper equipment. Radon is radioactive and can accumulate in enclosed spaces, posing health risks if inhaled in large amounts.
What are some effects of using uranium on the environment?
Uranium is a chemical element, toxic and radioactive. 1. Uranium is a possible polluting agent of the natural environment, lands and waters. 2. Uranium release radium and radon. Radon is also dangerous by inhalation - being a cause of some lung cancers. 3. The radioactivity of the environment is increased. 4. The contamination of living organisms can be harmful above a certain limit.
How dangerous is uranium mining?
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.
